BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a slider for a slide fastener having an automatic stop function and more particularly to a slider for a slide fastener with an automatic stopper which enables to simplify a structure of a slider body and also enables a pull to be easily installed on the slider body.  
         [0003]     2. Description of Related Art  
         [0004]     Conventionally, there has been often used a slider for a slide fastener having an automatic stop function in which by operating a pull to a slider body which couples/uncouples a zip teeth row of a fastener chain, a stop pawl of a stop pawl body is engaged with a part of the zip teeth row of the fastener chain so as to stop the slider body from moving (see for example, Japanese Utility Model Publication No. 4-32974).  
         [0005]     In a slider  100  described in Japanese Utility Model Publication No. 4-32974, as shown in  FIGS. 17 and 18 , a downward concave pull holding body  102  is fixed firmly on a slider body  101  from a shoulder side of an upper blade piece to a rear opening side. The base end portion of a stop pawl body  103  is mounted near the shoulder side of the same pull holding body  102  such that it is capable of moving vertically.  
         [0006]     An engaging pawl  105  projecting to a zip teeth row position on a fastener chain through an engagement window  104  formed in the upper blade piece of the slider body  101  such that it goes through vertically and an operation concave portion  107  which is opened to a rear opening side of the upper blade piece for accommodating the mounting shaft portion of a pull  106  are formed at a front end of the stop pawl body  103 . A bottom face of the base end portion of the stop pawl body  103  is always urged by a spring force of a compression coil spring placed in a small hole formed in the upper blade piece as shown in  FIG. 18  so as to project the engaging pawl  105  of the stop pawl body  103  to the zip teeth row position on the fastener chain through the engagement window  104 .  
         [0007]     As shown in  FIG. 18 , a gap portion  108  formed between an end portion on the side of the rear opening of the pull holding body  102  and the upper blade piece of the slider body  101  serves as a gap used for inserting the mounting shaft portion of the pull  106 . A closing member  109  for closing an insertion gap is disposed in this gap portion  108  so that it is capable of sliding between a gap closing position near the rear opening side and a gap opening position near a shoulder side. The closing member  109  is always urged toward the gap closing position.  
         [0008]     The closing member  109  is formed in a substantially U shape as seen in its plan view as shown in  FIG. 17 . At its two-branched arm portion, there are formed a first closing portion  110  for closing the gap portion  108  for a mounting shaft portion of the pull  106  not to be able to pass through the gap position and a second closing portion  114  for closing a continuous edge portion  113  which is continuous between a clearance  111  formed near the rear opening in right and left wall portions of the pull holding body  102  and an accommodating space  112  formed near a shoulder for the mounting shaft portion of the pull  106  not to be able to pass through. Both first and second closing portions  110 ,  114  project upwardly.  
         [0009]     For the slider  100  having the above-described structure, as shown in FIGS.  18  to  20 , the stop pawl body  103 , the closing member  109  and the pull holding body  102  are assembled on the slider body  101  except the pull  106  as a slider assembly product and then, the pull  106  is installed on the slider assembly product.  
         [0010]     Upon installation of the pull  106  onto the slider body  101 , as shown in  FIGS. 18 and 19 , the mounting shaft portion of the pull  106  is pressed into the gap portion  108  in the slider body  101  as a first step. If an outside end of the first closing portion  110  of the closing member  109  is pressed with the mounting shaft portion of the pull  106 , the first closing portion  110  leaves an end on the rear opening side of the pull holding body  102  as shown in  FIG. 19  so that the gap portion  108  is opened widely for the mounting shaft portion of the pull  106  to be able to pass through. After the mounting shaft portion is moved from the gap portion  108  into the clearance  111  in the pull holding body  102 , the closing member  109  returns to its original gap closing position by a restoration force of the spring as shown in  FIG. 20 .  
         [0011]     Next, as shown in  FIG. 20 , the mounting shaft portion of the pull  106  is moved from the clearance  111  in the pull holding body  102  into a concave portion formed between the first and second closing portions  110  and  114  of the closing member  109  as a second step. If the mounting shaft portion of the pull  106  is pressed into the gap portion  108  again as a third step, the second closing portion  114  looses out of a position of the continuous edge portion  113  in the pull holding body  102  as shown in  FIG. 19 . The mounting shaft portion of the pull  106  passes the bottom end of the continuous edge portion  113  in a condition in which it is accommodated in the concave portion and moves to the bottom end of the accommodating space  112  in the pull holding body  102 . At the same time, the mounting shaft portion of the pull  106  moves into an operation concave portion  107  in the stop pawl body  103  as indicated with a broken line in  FIG. 19 .  
         [0012]     As a fourth step, if the pull  106  is moved upward so as to move the mounting shaft portion of the pull  106  into the accommodating space  112  in the pull holding body  102 , an interference between the mounting shaft portion and the second closing portion  114  of the closing member  109  is eliminated. Consequently, the closing member  109  returns to the gap closing position due to a spring force and then, the installation of the pull  106  is completed. Then, if the closing member  109  returns to the gap closing position, the pull  106  is prevented from escaping out.  
         [0013]     After the installation of the pull  106 , if it is intended to remove the pull  106  out from the slider body  101 , the closing member  109  is moved to the gap opening position against an elastic force and with the closing member  109  held at the gap opening position, a reverse operation for the pull  106  to the above-mentioned operation is carried out. Consequently, the existing pull  106  can be removed out from the slider body  101  and a new pull can be installed instead of the existing pull  106 .  
         [0014]     As for an operation with the pull  106  installed in this way, if the pull  106  is pulled obliquely upward or in a sliding direction of the slider, the stop pawl body  103  is brought up against an elastic force through the operation concave portion  107  in the stop pawl body  103  by the mounting shaft portion of the pull  106 , so that the engaging pawl  105  of the stop pawl body  103  leaves the zip teeth row on the fastener chain. In this condition, the slider body  101  can be moved freely so as to mesh the zip teeth row on the fastener chain with each other. When the pull  106  is released from a hand, the stop pawl body  103  is urged by a spring so that the engaging pawl  105  is automatically inserted into the zip teeth row on the fastener chain through the engagement window  104  in the upper blade piece, thereby stopping the motion of the slider. Meanwhile the technology on the slider for the slide fastener with the automatic stopper disclosed in Japanese Utility Model Publication No. 4-32974 was previously proposed by the present inventor.  
         [0015]     Manufacturers of clothing, bags and the like have been demanded to prepare slider bodies and various types of pulls separately so as to install the diversified types of pulls each having a different color and shape onto the slider body corresponding to a request and desire of a customer.  
         [0016]     As a result, after an order on a slider corresponding to a request or desire of customer is received, the necessity of requesting a part manufacturer, who manufactures and sells fixing devices such as fasteners for, for example, bags, sport wears and other clothes to develop and manufacture a slider which fits to the request or desire of the customers again is eliminated, so that the manufacturers of clothing, bags and the like can meet such request or desire of the customer quickly.  
         [0017]     According to the related art described in Japanese Utility Model Publication No. 4-32974, the pull  106  can be installed on a slider assembly product detachably in the above-described manner. However, upon installing the stop pawl body  103  and the pull holding body  102  on the slider body  101  of the conventional slider  100 , it is necessary to form a shaft hole in each of a pair of mounting pieces, right and left, erected on the side of the shoulder of the slider body  101  and support the front end of the stop pawl body  103  between the respective mounting pieces so as to be vertically rotatable via a pin inserted into each shaft hole. Next, exposed end portions on both sides of the aforementioned pin are inserted into the shaft holes formed in the right and left side wall portions of the pull holding body  102  and the pull holding body  102  should be fixed on each mounting piece so that it is immobile by crimping each exposed end of the pin with respect to the right and left side wall portions of the pull holding body  102 .  
         [0018]     For the reason, the mounting structures of the stop pawl body  103  and the pull holding body  102  onto the slider body  101  become complicated. In case where the stop pawl body  103  and the pull holding body  102  are assembled on the slider body  101  using an automatic assembly machine, diversified apparatuses accompanied by that automatic assembly work are required thereby boosting its equipment cost and accompanied by an increase in the equipment cost, management cost and the like possibly increase. Further, because the mounting structures of the stop pawl body  103  and the pull holding body  102  to the slider body  101  become complicated, manufacturing cost of the slider increases, thereby making it impossible to produce at a low cost.  
         [0019]     According to the related art described in Japanese Utility Model Publication No. 4-32974, when the closing member  109  is pressed to the gap closing position of the slider body  101  as described above, the gap portion  108  formed between an end portion on the rear opening side of the pull holding body  102  and the upper blade piece of the slider body  101  is opened. Then, the mounting shaft portion of the pull  106  is inserted through the opening portion of this gap portion  108  to below the rear face of the pull holding body  102  and further inserted into the operation concave portion  107  in the stop pawl body  103 . Then, the installation of the pull  106  is completed.  
         [0020]     However, when engaging the pull  106  with the operation concave portion  107  in the stop pawl body  103 , it is necessary to move the pull  106  by amounts that allow it to go beyond top ends of sliding faces of the first and second closing portions  110 ,  114  of the closing member  109  while moving the closing member  109  by the pull  106  with resisting an elastic force.  
         [0021]     As a result, if the pull holding body  102  is set large, necessarily, the size of the closing member  109  increases, so that an excessive pressing force for that closing member  109  is necessary. Because such a strong pressing force is applied directly to the first and second closing members  110 ,  114  of the closing member  109  and the stop pawl body  103 , damage, deformation and the like are likely to occur in the closing member  109 , the stop pawl body  103  and the pull  106 , thereby worsening the assembly performance for the pull  106  and the slider body  101 .  
         [0022]     On the other hand, when removing an existing pull  106  from the slider assembly product, it is necessary to move the closing member  109  to a gap opening position resisting an elastic force so as to release an engagement between the pull  106  and the operation concave portion  107  in the stop pawl body  103 . By executing a reverse operation to the operation for engaging the pull  106  with the operation concave portion  107  in the stop pawl body  103  with the closing member  109  held at the gap opening position resisting an elastic force of the closing member  109 , it is necessary to pull out the pull  106  while moving it by the amounts which allows it to go beyond the top faces of the respective sliding faces of the first and second closing portions  110 ,  114 . For the reason, the mounting work for the pull  106  becomes complicated like a case where the pull  106  is engaged with the operation concave portion  107  in the stop pawl body  103 .  
         [0023]     The slider for the slide fastener with the automatic stopper described in Japanese Utility Model Publication No. 4-32974 is so constructed that its pull  106  can be replaced with a new pull different in color or shape by pulling out the pull  106  from the slider assembly product. Thus, the slider structure is complicated as described above and there is a limit in installing the pull on the slider assembly product accurately and thus, the installation work of the pull has been demanded to be facilitated. If such a demand can be satisfied, the pull can be installed on the slider body reasonably.  
       SUMMARY OF THE INVENTION  
       [0024]     Accordingly, the present invention has been achieved to solve the conventional problems and an object of the present invention is to provide a slider for a slide fastener with an automatic stop function, which enables a structure of its slider body to be simplified, its manufacturing cost to be reduced, and further a pull to be installed easily while securing such a stable and excellent automatic stop function.  
         [0025]     To achieve the above-described object, according to a main aspect of the present invention, there is provided a slider for a slide fastener with an automatic stopper comprising: a slider body for engaging/disengaging a zip teeth row of a fastener chain; mounting pillars provided on a top face of the slider body; a pawl body which is mounted on the top face of the slider body such that it is capable of swinging vertically and engages and disengages a part of the zip teeth row in the fastener chain through the inside of the slider body; a concave portion which is formed in the pawl body and opened to one of the mounting pillars for accommodating a shaft portion of a pull; a pull holding body which engages with the mounting pillars, engaging portions provided on the mounting pillars; and engaged portions to be engaged with the engaging portions provided on the pull holding body, wherein a gap portion which allows a shaft portion of the pull to pass through is formed between an opening end of the concave portion and the mounting pillar, the mounting pillars or the pull holding body has closing means for closing a part of the gap portion and preventing the pull from escaping from the opening end of the concave portion.  
         [0026]     Preferably, the mounting pillars and the pull holding body have lateral moving preventing means for preventing the pull holding body from moving in right and left directions relative to the slider body, and the lateral moving preventing means comprises supporting walls erected on right and left edges of the mounting pillars and wall portions of the pull holding body fit and supported between the right and left supporting walls.  
         [0027]     Further preferably, the mounting pillars comprise a front mounting pillar provided on a front portion of the slider body and a rear mounting pillar on a rear portion of the slider body, the pull holding body comprises the wall portions constituted of a top wall portion, front and rear wall portions extending from front and rear ends of the top wall portion, and the front and rear wall portions comprise the engaged portions.  
         [0028]     Preferably, the closing means comprises right and left wall portions projecting downward from right and left sides of the top wall portion of the pull holding body and when the pull holding body is engaged with the mounting pillars, the right and left wall portions cover and close the gap portion.  
         [0029]     Preferably, pull guide faces for guiding a shaft portion of the pull are formed in the right and left wall portions respectively.  
         [0030]     Preferably, the closing means comprises the mounting pillar and the mounting pillar is disposed slidably to an opening end of the concave portion and closes the gap portion at a position close to the opening end of the concave portion while a positioning portion for positioning the mounting pillar at the position close to the opening end is formed on the slider body.  
         [0031]     Further Preferably, a fitting guide groove for guiding the mounting pillar in its fitting condition are formed in the top face of the slider body while fitting portions which are fit to the fitting guide groove are formed on the mounting pillar.  
         [0032]     The slider for the slide fastener with the automatic stopper of the present invention has a first prominent feature in that the engaging portions are formed in the mounting pillars of the slider body and that the engaged portions capable of being engaged with the engaging portions on the mounting pillars can be formed on the pull holding body.  
         [0033]     The slider of the present invention has a second prominent feature in that during an assembly process before the pull holding body is mounted on the slider body over the pawl body after the pawl body which is engaged with and disengaged from a part of the zip teeth row on the fastener chain through the inside of the slider body is installed on the slider body such that it is capable of swinging vertically, the gap portion which allows the shaft portion of the pull to pass through can be formed between the mounting pillar and the concave portion in the pawl body.  
         [0034]     Further the slider of the present invention has a third prominent feature in that after the shaft portion of the pull is inserted into the concave portion in the pawl body through the gap portion, the closing means for closing at least a part of the gap portion and preventing the pull from escaping from the opening end of the concave portion in the pawl body can be formed in the mounting pillars or the pull holding body. “Closing a part of the gap portion” mentioned in the description about the first aspect of the present invention and this specification means narrowing the interval in the gap portion to a very small one.  
         [0035]     According to the present invention, the pull holding body can be held in an immobile condition and firmly to the mounting pillars of the slider body. Thus, after the pawl body is installed on the top face of the slider body and then the shaft portion of the pull is mounted in the concave portion in the pawl body movably through the gap portion, the pull holding body can be engaged with the mounting pillars from above the pawl body and the pull. Consequently, the shaft portion of the pull can be blocked from escaping out from the opening end of the concave portion in the pawl body through the gap portion securely.  
         [0036]     Further, with a simple structure, the gap portion can be formed between the opening end of the concave portion in the pawl body and the mounting pillar and at least a part of the gap portion can be closed by the pull holding body. Further, the shaft portion of the pull and the pawl body can be actuated smoothly and securely in a space portion formed between a rear face of the pull holding body and the top face of the slider body. As a consequence, damage, improper deformation and trouble of the pawl body can be prevented thereby improving its durability.  
         [0037]     The slider can be manufactured with a simple structure without a necessity of providing the slider body with any special closing member or complicated structure as described in Japanese Utility Model Publication No. 4-32974. Upon installation of the pull on the top face of the slider body, the pawl body, the pull and the pull holding body can be assembled in order on the top face of the slider body. Consequently, the assembly performance and reliability can be improved considerably and tractability is high.  
         [0038]     Further, the pull and the pull holding body can be assembled appropriately onto the slider body loaded with the pawl body as a complete slider product. The assembly can be carried out not only with an automatic assembly machine but also easily and securely with man power. Upon installation of the pull on the top face of the slider body, a simple processing apparatus may be employed without a necessity of any special accessory equipment or peripheral machine. As a consequence, processing cost is reduced and productivity can be improved, thereby manufacturing cost of the slider being reduced.  
         [0039]     Because the pull holding body can be fit to the mounting pillars and installed firmly and securely, the pull holding body does not have to be formed in any complicated configuration, but a simple rectangular plate-like structure, for example, may be adopted for the pull holding body. As a consequence, reductions in size and thickness of the slider can be achieved. Further, an installation positions of the engaging portions of the mounting pillars are not restricted to any special position, and the engaging portions may be formed on a front face of the front mounting pillar and a rear face of the rear mounting pillar, for example.  
         [0040]     As the engaging portions on the mounting pillars, which are applied to the present invention, it is permissible to use for example, engaging concave portions, cutouts, hole portions, protrusions or the like. As the engaged portions of the pull holding body, it is permissible to adopt elastic pieces, pawls or the like which are engaged with the engaging portions in the mounting pillars. If the engaging portions of the mounting pillars themselves have elastic structures, the engaged portions of the pull holding body may be formed in a structure or configuration such as a simple protrusions having stiffness.  
         [0041]     According to the present invention, the mounting pillars and the pull holding body can be provided with lateral moving preventing means for preventing themselves from moving relatively to the right or left side. As a typical structure of the lateral moving preventing means, the lateral moving preventing means can be constructed with the supporting walls erected on the right and left edges of the mounting pillars, and the wall portions of the pull holding body. The top wall portion and front and rear wall portions at the front and rear ends of the pull holding body can be fit to and supported between the right and left supporting walls of the mounting pillars.  
         [0042]     The pull holding body can be prevented from moving in back and forth directions and further, the mounting pillars and pull holding body can be maintained in an immobile state with the lateral moving preventing means. As a consequence, even if a strong force intending to release an engagement between the engaging portions of the mounting pillars and the engaged portions of the pull holding body is applied according to the operation of the pull, a holding force to the pull holding body can be increased without distorting the pull holding body in the back and forth directions, right and left directions, obliquely or in a vertical direction.  
         [0043]     The lateral moving preventing means may be formed on the top faces of the mounting pillars and an opposing face of the pull holding body to the mounting pillars and may be a protrusion or a concave portion which if fitted to each other. In this case, the lateral moving preventing means can be constructed of the protrusions formed on the top faces of the mounting pillars or the opposing face of the pull holding body to the mounting pillars and the concave portions formed on the other one of the top faces of the mounting pillars and the opposing face of the pull holding body to the mounting pillars.  
         [0044]     Fixing areas of the slider body and the pull holding body can be secured without exposing any special fixing structure outside the slider body and the pull holding body. Further, by setting the protrusion and the concave portion which are the lateral moving preventing means appropriately at positions on which a pulling force of the pull is likely to act, a strong holding force for the pull holding body can be obtained, and the gap portion and the closing means can be set reasonably.  
         [0045]     When the engaged portions of the pull holding body is engaged with the engaging portions of the mounting pillars, the supporting walls of the mounting pillars are fit to the wall portions of the pull holding body, so as to support and fix the pull holding body firmly and securely. Despite such a simple structure in which the supporting walls are fit to the wall portions of the pull holding body, both of the pull holding body and the respective pillars are integrated with each other so that they are not separable, thereby improving the assembly performance and reliability or the like remarkably. Therefore, the pull holding body does not have to be constructed in any complicated structure, and it is permissible to adopt a simple horizontal C shape for the pull holding body. Consequently, reductions in size and thickness of the slider can be achieved and tractability is high.  
         [0046]     Further, at least the wall portions of the pull holding body are fit between the opposing faces of the right and left supporting walls of the mounting pillars, so that the pull holding body can be disposed flush with the top face of the respective mounting pillars. At the same time, the thickness thereof can be reduced, thereby reductions in weight and size of the slider being achieved. Consequently, a slider excellent in appearance design and having a high value as a product is produced effectively.  
         [0047]     As a typical structure of the closing means of the present invention, the right and left wall portions projecting downward from right and left sides of the top wall portion of the pull holding body can be constructed as the closing means, like the embodiment of the third aspect. The right and left wall portions of the pull holding body project into a space formed between a rear face of the pull holding body and the top face of the slider body when the pull holding body is engaged with the mounting pillars. Consequently, the right and left wall portions cover and close the gap portion between the opening end of the concave portion in the pawl body and the mounting pillars.  
         [0048]     According to the above-described structure, if the pull is raised upward, the shaft portion of the pull makes contact with the right and left wall portions, thereby limiting a distance of an upward movement of the shaft portion of the pull. Thus, the pull can be prevented from escaping out from the opening end of the concave portion in the pawl body. Further, it is possible to secure a function which allows the pawl portion of the pawl body to engage with and disengage from a part of the zip teeth row on the fastener chain without generating an excessive deformation in the pawl body.  
         [0049]     The right and left wall portions can be provided with a pull guide face for guiding the shaft portion of the pull as mentioned in the fourth aspect of the invention. When the pull holding body is engaged with the mounting pillars, the shaft portion of the pull can be positioned securely and a swing of the pawl body can be carried out smoothly and easily by operating the pull. Because no excessive deformation is caused in the pawl body, the pawl body can be restored to its original state smoothly and securely and the function of the pawl body can be secured for a long time.  
         [0050]     As another typical structure example of the closing means of the present invention, the closing means can be constructed with a mounting pillar, like the fifth aspect of the invention. This mounting pillar can be constructed to be fit to the top face of the slider body and capable of sliding thereon between a position where the gap portion which allows the shaft portion of the pull to pass through is closed and a position where the gap portion is formed. Thus, when mounting the pull over the top face of the slider, the gap portion can be formed as a required gap.  
         [0051]     With the above-described structure, the gap portion can be closed with the mounting pillar at a position where the mounting pillar is approached with a predetermined gap with respect to the opening end of the concave portion when the mounting pillar is slid on the top face of the slider body and then, the mounting pillar can be positioned by the positioning portion. Consequently, the shaft portion of the pull can be inserted into the concave portion in the pawl body accurately and stably, thereby achieving a highly stabilized and excellent assembly performance. After the shaft portion of the pull is mounted in the concave portion in the pawl body, the pull holding body can be engaged with the mounting pillars at the position of which the mounting pillar approaches.  
         [0052]     As a structure for sliding the mounting pillar with respect to the top face of the slider body, a fitting guide groove for guiding the mounting pillar in the fitting condition can be formed in the top face of the slider body, like the sixth aspect of the invention, and the fitting portion which is fitted to the fitting guide groove can be formed on the mounting pillar.  
         [0053]     With the above-described structure, the fitting guide groove can be formed along the top face of the slider body toward the opening end of the concave portion in the pawl body. Thus, the mounting pillar can be guided accurately and stably toward the pawl body and further, mounted simply and accurately.  
         [0054]     A sufficient attachment strength of the slider body and the mounting pillar can be secured without exposing any special attachment structure outside of the slider body and the mounting pillar. Further, by setting the protrusion and concave portion appropriately at positions which allow the mounting pillar to slide easily, a strong holding force of the mounting pillar to the slider body can be obtained. In the meantime, the fitting guide groove in the slider body and the fitting portion on the mounting pillar may be a protrusion or a concave portion which is fitted to each other, for example, a protrusion formed in the fitting guide groove and a concave portion formed in the fitting portion.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0075]     Hereinafter the preferred embodiments of the present invention will be described with reference to the accompanying drawings.  
         [0076]     FIGS.  1  to  9  show a typical first embodiment of the present invention.  FIG. 1  is a perspective view showing a state in which components constituting a slider for a slide fastener with an automatic stopper are disassembled, FIGS.  2  to  8  are longitudinal sectional views of major portions showing assembly steps of the same slider, and  FIG. 9  is a perspective view of the same slider. In this embodiment, a side of a shoulder (left side in  FIG. 1 ) of the slider is called as a front portion while a side of a rear opening (right side in  FIG. 1 ) of the slider is called as a rear portion.  
       First Embodiment  
       [0077]     Referring to  FIG. 1 , the slider for the slide fastener with the automatic stopper  10  comprises a slider body  20 , a front mounting pillar  25 , a rear mounting pillar  26 , a pawl body  30 , a pull holding body (cover body)  40 , a pull  50  and the like. The pawl body  30  and the pull holding body  40  can be manufactured by press molding using metallic material such as stainless and/or copper alloy. On the other hand, the slider body  20 , the front mounting pillar  25 , the rear mounting pillar  26  and the pull  50  can be manufactured by die-cast molding using metallic material such as aluminum alloy and zinc alloy. In the meantime, these members can be manufactured by injection molding using thermoplastic resin such as polyamide, polypropylene, polyacetal, polybutylene terphthalate and the like or thermoplastic resin material added with wear resistant reinforcing material, instead of metal materials.  
         [0078]     As shown in  FIG. 2 , the slider body  20  comprises an upper blade piece  21 , a lower blade piece  22  and a connecting pillar  23  for connecting front end portions of the upper and lower blade pieces  21 ,  22 . The upper and lower blade pieces  21 ,  22  have upper and lower flanges  21   a ,  22   a  respectively on the right and left sides from a rear end to substantially a central portion. A Y-shaped engaging element guide path  24  is formed between the upper and lower blade pieces  21  and  22 .  
         [0079]     As shown in  FIG. 1 , the front mounting pillar  25  having a typical structure of the present invention is formed integrally with a top face of the front portion of the upper blade piece  21  of the slider body  20  such that it stands upright therefrom. This front mounting pillar  25  comprises a pair of front supporting walls  25   a ,  25   a  separated with an interval corresponding to an outer shape of the pull holding body  40 . As shown in  FIGS. 1 and 2 , a step portion  25   c , is formed in each of the opposing faces of the front supporting walls  25   a  so that the step portion is lowered only by a predetermined depth from a top edge while a projecting portion  25   b  is left at a rear end corner. A step face of the step portion  25   c  is formed as a contact face for the pull holding body  40  in order to prevent it from invading further when the pull holding body  40  is fitted between the front supporting walls  25   a . A top face of the projecting portion  25   b  is disposed at substantially the same height as a top face of the pull holding body  40  when the pull holding body is fitted.  
         [0080]     A linear engaging portion  25   d , which extends between right and left side faces as shown in  FIG. 2 , is formed integrally with front opposing faces of the front supporting walls  25   a . This engaging portion  25   d  is formed in a step-like shape comprising a guide slope face which is inclined downward smoothly along the step face of each of right and left step portions  25   c  and an edge engaging face which engages with/disengages from the pull holding body  40 .  
         [0081]     As shown in  FIGS. 1 and 2 , a pawl accommodating concave portion  21   b  extended longitudinally is formed in the central portion of the top face of the upper blade piece  21  between the opposing faces of the front supporting walls  25   a  as a mounting face for the pawl body  30 . As shown in  FIG. 2 , a spring accommodating hole  21   c  is made in a central portion at a front end of a bottom face of this pawl accommodating concave portion  21   b . A compression coil spring  11  for urging the pawl portion  31  of the pawl body  30  to make the pawl portion  31  project into the engaging element guide path  24  after an installation of the pawl body  30  is accommodated within the spring accommodating hole  21   c.    
         [0082]     A pair of right and left pawl mounting portions  21   d ,  21   d  are integrally formed on the top face of the upper blade piece  21  between rear opposing faces of the front supporting walls  25   a  such that they project upward adjacent both side edges of the pawl accommodating concave portion  21   b . A top face of each of the pawl mounting portions  21   d  is divided into two branches. A gap in the pawl mounting portion  21   d  is constructed as a pin supporting hole for a pin  12  for supporting the pawl body  30  so that it is capable of swinging vertically. The pin  12  is fixed on the top face of the upper blade piece  21  by crimping the two branches of the pawl mounting portion  21   d  after the pawl body  30  is mounted as shown in  FIG. 3 .  
         [0083]     As shown in  FIGS. 1 and 2 , a short base piece and a long piece of flat plate materials are formed integrally at front and rear end portions of the pawl body  30 . As shown in  FIG. 3 , a supporting concave portion  33  for supporting the pawl body  30  by the pin  12  supported and fixed by the pawl mounting portion  21   d  is formed between the base piece and the long piece. This supporting concave portion  33  is formed into a desired depth and shape which enable the pin  12  to support the pawl body  30 . A bottom face of a base end of the pawl body  30  is constructed to act as a mounting face which is mounted on the compression spring  11 . A concave portion  32 , which is open to the rear mounting pillar  26  for accommodating a shaft portion  51  of the pull  50 , is formed at a front end of the pawl body  30 . The pawl portion  31 , which engages with engaging elements of a slide fastener (not shown) so as to stop the slider body  20  from moving, is formed integrally on the bottom face at the front end of the pawl body  30  such that it is bent downward.  
         [0084]     A first prominent feature of the slider  10  of the present invention exists in that as shown in  FIG. 8 , engaging portions  25   d ,  26   d  are formed on the paired mounting pillars  25 ,  26  and that engaged portions  41   a ,  42   a  which is engaged with the engaging portions  25   d ,  26   d , can be formed on the pull holding body  40 .  
         [0085]     A second prominent feature of the present invention exists in that a gap portion  60  for the shaft portion  51  of the pull  50  to pass through is formed between the rear mounting pillar  26  and the pawl body  30  during an assembly step before the pull holding body  40  is mounted on the top face of the upper blade piece  21  after the pawl body  30  is mounted on the top face of the upper blade piece  21  so that it is capable of swinging vertically as shown in  FIG. 3 .  
         [0086]     Further a third prominent feature of the present invention exists in that when the pull holding body  40  is engaged with the respective mounting pillars  25 ,  26  as shown in FIG.  8 , it is possible to form closing means which partially closes the gap portion  60  ( FIG. 3 ) and prevents the pull  50  from escaping from an opening end of the concave portion  32  in the pawl body  30 . “Partially closing the gap portion  60 ” mentioned here means narrowing an interval of the gap portion  60  to a very small extent.  
         [0087]     According to the first embodiment, an initial object of the present invention can be achieved by constructing the rear mounting pillar  26 , which is fitted to a rear top face of the upper blade piece  21 , so that it is capable of sliding. The rear mounting pillar  26  indicating a typical structure example of the present invention has a pair of right and left rear supporting walls  26   a ,  26   a  set to a same width as the front mounting pillar  25  as shown in  FIGS. 1 and 2 . A step portion  26   c  which is lowered by a predetermined depth from a top edge while a projecting portion  26   b  is left at a front end corner is formed on each of opposing faces of the supporting walls  26   a . A step face of the step portion  26   c  is formed as a contact face for the pull holding body  40 . A concave portion, which forms a part of an operating space of the pawl body  30 , is formed at a front face of the rear mounting pillar  26 .  
         [0088]     A linear engaging portion  26   d  is formed integrally such that it extends between right and left side faces on opposing faces near rear ends of the rear supporting walls  26   a . The engaging portion  26   d  is constructed in a step-like shape comprising a guide slope face which is inclined downward smoothly along a surface of the step portion  26   c  and an edge engaging face which engages with/disengages from the pull holding body  40 . The structure of the rear mounting pillar  26  is not substantially different from that of the front mounting pillar  25  except that it is constructed so as to be capable of sliding with respect to the upper blade piece  21 .  
         [0089]     A fitting guide groove  27 , in which a bottom end portion of the rear mounting pillar  26  is inserted and fitted, can be formed in a top face of a rear portion of the upper blade piece  21 . This fitting guide groove  27  is formed to have grooves having a substantially U shaped section on its right and left sides while it extends from the rear end to substantially the central portion of the upper blade piece  21  as shown in  FIGS. 1 and 2 . As shown in  FIGS. 1 and 4 , rectangular protrusions which are fitting portions  26   e ,  26   e , fitted to the fitting guide groove  27 , are formed so as to project from parts of the rear supporting walls  26   a ,  26   a  of the rear mounting pillar  26 . (Hereinafter each of the fitting portions  26   e  are referred to as a protrusion  26   e .) In the meantime, the fitting guide groove  27  in the upper blade piece  21  and the protrusion  26   e  of the rear mounting pillar  26  may be formed to a protrusion or a concave portion which is fitted to each other and it is needless to say that, for example, a protrusion formed in the fitting guide groove  27  and a concave portion formed in the rear mounting pillar  26  can be used and the present invention is not restricted to the example represented here.  
         [0090]     Front end faces intersecting the pawl body accommodating portion  21   b  in the fitting guide groove  27  can be constructed as positioning portions  21   g  for the rear mounting pillar  26  that prevent the rear mounting pillar  26  from invading further when it is fitted into the fitting guide groove  27  as shown in  FIGS. 1 and 2 . In the meantime, the requirement condition for a positioning portion  21   g  is to position the rear mounting pillar  26  at such a position that after the shaft portion  51  of the pull  50  is mounted in the concave portion  32  of the pawl body  30 , enables the respective mounting pillars  25 ,  26  and the pull holding body  40  to be engaged with each other while closing the gap portion  60 . It is needless to say that, for example, the positioning portion  21   g  can be formed within the fitting guide groove  27  or at a predetermined position on the top face of the upper blade piece  21 .  
         [0091]     As shown in  FIGS. 4 and 5 , a concave cutout portion having a concave step is formed inward from an end face of an upper holding piece of the fitting guide groove  27  and slip-out preventing portions  27   a ,  27   a  are formed through the concave cutout portions. After the protrusions  26   e  of the rear mounting pillar  26  are fit to the fitting guide groove  27 , the slip-out preventing portions  27   a  can be deformed elastically by crimping with respect to the top face of the upper blade piece  21  according to a normal method. Consequently, a stopper portion which prevents the rear mounting pillar  26  form escaping out can be formed. In the meantime, the slip-out preventing portion  27   a  can be formed at a predetermined position of the top face of the upper blade piece  21  instead of being formed within the fitting guide groove  27 .  
         [0092]     As shown in  FIG. 3 , the fitting guide groove  27  extends from the rear end of the upper blade piece  21  toward the concave portion  32  in the pawl body  30  in a condition in which the pawl body  30  is mounted on the upper blade piece  21 . Consequently, the rear mounting pillar  26  can be introduced and guided accurately and stably toward the opening end of the concave portion  32  in the pawl body  30  after the pawl body  30  is mounted on the top face of the upper blade piece  21 , thereby realizing an excellent assembly performance ensuring a high stability.  
         [0093]     As a result, due to the fitting guide groove  27  and the protrusions  26   e , fixing areas of the slider body  20  and the rear mounting pillar  26  can be secured without exposing any special fixing structure outside the slider body  20  and the rear mounting pillar  26 . Consequently, the fitting guide groove  27  and the protrusions  26   e  can be set up appropriately at a portion which allows the rear mounting pillar  26  to slide easily and a firm holding force for the rear mounting pillar  26  with respect to the slide body  20  can be obtained.  
         [0094]     When the rear mounting pillar  26  is mounted on the top face at the rear portion of the upper blade piece  21 , the rear mounting pillar  26  can be set at positions where the gap portion  60  allowing the shaft portion  51  of the pull  50  to pass between the rear mounting pillar  26  and the pawl body  30  is closed as shown in  FIG. 7  and where the gap portion  60  is formed as shown in  FIG. 3 . At the position where a rear end portion of the rear mounting pillar  26  makes contact with the slip-out preventing portion  27   a , a maximum gap which allows the shaft portion  51  of the pull  50  to pass through can be secured sufficiently in the gap portion  60 . On the other hand, the pull holding body  40  can be engaged with the respective mounting pillars  25 ,  26  at a position where the gap portion  60  is closed.  
         [0095]     When mounting the rear mounting pillar  26  onto the top face of the rear end of the upper blade piece  21 , it is possible to employ an automatic machine thereby improving the assembly work of the slider  10  efficiency. A predetermined gap is provided between the front mounting pillar  25  and the rear mounting pillar  26 , so that the pawl body  30  and a part of the pull  50  are accommodated and a sufficient space for accommodating the pull holding body  40  can be formed.  
         [0096]     As shown in  FIGS. 1 and 2 , a pair of sheet-like right and left pull guide pieces  21   e ,  21   e  are formed integrally at corners in which the fitting guide groove  27  and the pawl body accommodating concave portion  21   b  intersect each other substantially in the central portion of the upper blade piece  21  such that they project upward substantially in triangular shapes as seen in a side view. Each pull guide piece  21   e  is disposed on the upper blade piece  21  which transverses the concave portion  32  in the pawl body  30  in a condition in which the pawl body  30  is mounted on the upper blade piece  21  as shown in  FIG. 3 . Further, a rectangular pawl hole portion  21   f , through which the pawl portion  31  of the pawl body  30  is inserted and removed, is formed adjacent a rear base end of the pull guide piece  21   e  such that it pierces the upper blade piece  21  vertically within the fitting guide groove  27 . The pawl hole portion  21   f  communicates with the engaging element guide path  24 .  
         [0097]     As shown in  FIG. 3 , the concave portion  32  in the pawl body  30  mounted in the pawl accommodating concave portion  21   b  in the upper blade piece  21  is always urged downward by a spring force of the compression coil spring  11  in a condition in which it strides between the pull guide pieces  21   e . Thus, the pull guide piece  21   e  can be constructed as a stopper portion for preventing the shaft portion  51  of the pull  50  from escaping from the concave portion  32  in the pawl body  30  in cooperation with a downward urging force of the pawl body  30  in a condition in which the shaft portion  51  of the pull  50  is mounted in the concave portion  32  of the pawl body  30  before the gap portion  60  is closed by the rear mounting pillar  26 .  
         [0098]     A rear end face of the pull guide piece  21   e  can be constructed as a pull guide face  21   e - 2  for guiding the shaft portion  51  of the pull  50  toward an opening end of the concave portion  32  along its tapered face which is inclined upward gradually in a forward direction when mounting the shaft portion  51  of the pull  50  in the concave portion  32  of the pawl body  30  before an operation for closing the gap portion  60  with the rear mounting pillar  26  as shown in  FIG. 6 . A front end face of the pull guide piece  21   e  is also constructed as a pull guide face  21   e - 1  for guiding the shaft portion  51  of the pull  50  toward the concave portion  32  along its tapered face which is inclined upward gradually in a backward direction when mounting the shaft portion  51  of the pull  50  in the concave portion  32  of the pawl body  30  as shown in  FIG. 2 . Further, the front end face of the pull guide piece  21   e  can be made to function as the pull guide face  21   e - 1  for guiding the pull  50  from a front base end of the pull guide piece  21   e  toward a moving limit position of the pawl body  30  when operating the pull  50  after the slider  10  is assembled as shown in  FIG. 8 .  
         [0099]     Further according to the present invention, it is permissible to provide the respective mounting pillars  25 ,  26  and the pull holding body  40  with lateral moving preventing means in order to prevent the respective mounting pillars  25 ,  26  and the pull holding body  40  from moving relatively in the lateral direction. The lateral moving preventing means can be constructed with the supporting walls  25   a ,  26   a  erected on the right and left ends of the respective mounting pillars  25 ,  26  and a top wall portion  45  and front and rear wall portions  41 ,  42  at front and rear ends of the pull holding body  40 . By fitting the respective wall portions  41 ,  42  among the respective supporting walls  25   a ,  25   a  and  26   a ,  26   a , the pull holding body  40  can be maintained in an immobile condition with respect to the respective mounting pillars  25 ,  26 .  
         [0100]     As shown in  FIG. 1 , the pull holding body  40  is composed of a thin long plate material. The pull holding body  40  is constructed of a substantially horizontal C shaped cover body having front and rear wall portions  41 ,  42  projecting downward from a flat top wall portion  45  so as to be curved smoothly with the same curvature before and after the top wall portion  45 . Engaged portions  41   a ,  42   a  which are elastically engaged with/disengaged from edge engaging faces of the engaging portions  25   d ,  26   d  of the respective mounting pillars  25 ,  26  project from inner faces at front ends of the wall portions  41 ,  42 .  
         [0101]     Right and left wing pieces, which are right and left wall portions  43 ,  43  partially covering a space portion between the front mounting pillar  25  and the rear mounting pillar  26  for shielding, project to right and left sides of the upper wall portion of the pull holding body  40 . (Hereinafter each of the right and left wall portions  43  is called as a wing piece  43 .) Upper faces of the right and left wing pieces  43  are curved downward with the same curvature so as to form a convex curved face. Lacking portions  44 , which fit and engage with each pair of projecting portions  25   b ,  26   b  of the front mounting pillar  25  and the rear mounting pillar  26 , are formed at ridge line portions (corners) between the right and left wing pieces  43  and the upper wall portion. The lacking portions  44  are formed in a stepped shape which is concave inward from both linear side end faces of the right and left wing pieces  43 .  
         [0102]     The right and left wing pieces  43  can be formed in a substantially same length as an interval between the front mounting pillar  25  and the rear mounting pillar  26  and shorter than a vertical length of each of the front and rear wall portions  41 ,  42 . Thus, when the pull holding body  40  is mounted on the slider body  20 , bottom end faces of the right and left wing pieces  43  keep apart from the top face of the upper blade piece  21 , thereby forming a space portion which allows the shaft portion  51  of the pull  50  to move.  
         [0103]     A space surrounded by a rear face of the pull holding body  40  and the top face of the upper blade piece  21  acts as an operation space portion which allows the shaft portion  51  of the pull  50  and the pawl body  30  to be operated when the pull holding body  40  is engaged with the slider body  20 . In this operation space portion, the shaft portion  51  of the pull  50  and the pawl body  30  can be operated smoothly and securely. Further, the pawl body  30  can be protected from a damage, improper deformation, a trouble and the like, thereby improving its durability.  
         [0104]     With the above-described structure, the top wall portion  45  and the front and rear wall portions  41 ,  42  of the pull holding body  40  is fitted and supported between the opposing faces of the supporting walls  25   a ,  26   a  of the front and rear mounting pillars  25 ,  26 , so that a top face of the top wall portion  45  and top faces of the front and rear wall portions  41 ,  42  can be made flush with top faces of the supporting walls  25   a ,  26   a . For the reason, the pull holding body  40  can be formed in a minimum thickness of necessary level and reduction in size and thinning in the structure of the slider  10  can be achieved. Further it is possible to obtain a slider highly valuable as a product and excellent in its appearance design.  
         [0105]     The engaged portions  41   a ,  42   a  of the pull holding body  40  is engaged with the engaging portions  25   d ,  26   d  of the front and rear mounting pillars  25 ,  26  elastically and the pull holding body  40  is accommodated between the pairs of supporting walls  25   a ,  26   a  of the front and rear mounting pillars  25 ,  26  while the lacking portions  44  in the pull holding body  40  fit the paired projecting portions  25   b ,  26   b  on the front mounting pillar  25  and the rear mounting pillar  26 .  
         [0106]     Because the pull holding body  40  is fitted between the supporting walls  25   a ,  26   a  of the respective mounting pillars  25 ,  26  while the lacking portions  44  in the pull holding body  40  are fit to the projecting portion  25   b ,  26   b  on the mounting pillars  25 ,  26 , the pull holding body  40  is installed firmly and securely without oscillating with respect to any force in back and forth directions and width direction. As a result, after the pawl body  30  is mounted on the top face of the slider body  20  and the shaft portion  51  of the pull  50  is mounted movably within the concave portion  32  in the pawl body  30  through the gap portion  60 , the pull holding body  40  can be engaged with the respective mounting pillars  25 ,  26  over the pawl body  30  and the pull  50 . Consequently, the shaft portion  51  of the pull  50  can be prevented from escaping from the opening end of the concave portion  32  in the pawl body  30  through the gap portion  60  securely, so that the pawl body  30  can be held smoothly and securely thereby securing the quality of the slider  10  for a long term.  
         [0107]     The lateral moving preventing means which can be applied to the present invention may be formed on a top face of each of the mounting pillars  25 ,  26  and an opposing face of the pull holding body  40  to the respective mounting pillars  25 ,  26  and needless to say, it may be a protrusion or a dented portion which is fitted to each other. By setting a protrusion or a dented portion (not shown) at a portion on which a pulling force of the pull  50  acts easily, a holding force of the pull holding body  40  can be obtained strongly, so that the gap portion  60  and the closing means can be set up appropriately. As an example, it is possible to construct the lateral moving preventing means with a protrusion formed either on the top faces of the respective mounting pillars  25 ,  26  or opposing faces of the pull holding body  40  to the mounting pillars  25 ,  26 , and a dented portion formed on the other one of the top faces of the mounting pillars  25 ,  26  and the opposing faces of the pull holding body  40  to the mounting pillars  25 ,  26 .  
         [0108]     As the engaging portions  25   d ,  26   d  of the respective mounting pillars  25 ,  26  which are applied to the present invention, for example, an engagement concave portion, a cutout portion, a hole portion, a protrusion and the like can be used. As the engaged portions  41   a ,  42   a  of the pull holding body  40 , it is possible to adopt an elastic piece, a pawl and the like which is engaged with the engaging portions. If the engaging portions themselves have an elastic structure, the engaged portions may be formed into a structure or configuration of mere protrusions having stiffness.  
         [0109]     Although the pull holding body  40  shown here is structured with a cover body made of a thin long sheet material, the present invention is not restricted to this example. It is permissible to employ, for example, a rectangular box comprising a top wall, front and rear wall portions, and right and left wall portions with a cutout at a center. Further, installation positions of the engaging portions  25   d ,  26   d  on the mounting pillars  25 ,  26  are not restricted to any particular one, however, if for example, a pull holding body  40  is constructed with a rectangular box, engaging portions can be formed on right and left side faces of front and rear mounting pillars.  
         [0110]     The pull  50  is constructed with a short sheet material as shown in  FIG. 1 . This pull  50  has a ring-like grip portion at an end thereof and a ring-like holding portion  52  having a substantially square hole portion to which the rear mounting pillar  26  can be fit at the other end side. A front end portion of the ring-like holding portion  52  is formed in a shape of a bridge as the shaft portion  51  having a circular section. A length of the shaft portion  51  is set to be larger than a width of the rear mounting pillar  26  and when the pull is mounted, the shaft portion  51  is guided by the pull guide piece  21   e  of the upper blade piece  21  while striding over the rear mounting pillar  26 , thereby being inserted.  
         [0111]     Next, an example of assembly procedure of the slider  10  of the present invention will be described with reference to FIGS.  2  to  9 .  
         [0112]     To assemble the slider  10  constructed as mentioned above, as shown in  FIG. 2 , first of all, the compression coil spring  11  is accommodated in the spring accommodating hole  21   c  in the upper blade piece  21 . Next, the pawl body  30  is placed on the pawl body accommodating concave portion  21   b  in the upper blade piece  21  in a substantially vertical posture while pressing the compression coil spring  11  with the base end of the pawl body  30  to deform it elastically. Next, the pin  12  is inserted so as to stride over the pin supporting hole in each pawl body mounting portion  21   d  of the upper blade piece  21  and the supporting concave portion  33  in the pawl body  30  and then, the two branch portions of the pawl body mounting portion  21   d  is crimped so as to fix the pin  12 .  
         [0113]     At this time, the pawl portion  31  of the pawl body  30  is inserted into the pawl hole portion  21   f  in the upper blade piece  21  and the pawl body  30  is disposed on the top face of the upper blade piece  21  in a condition in which it is entirely inclined upward from the pawl hole portion  21   f  toward the front mounting pillar  25 . The base end portion of the pawl body  30  is disposed between the opposing faces of the supporting walls  25   a  of the front mounting pillars  25  in a condition in which it is always urged by the compression spring  11 .  
         [0114]     After the pawl body  30  is mounted on the top face of the upper blade piece  21  such that it is capable of swinging vertically, the protrusions  26   e  of the rear mounting pillar  26  are inserted into the fitting guide groove  27  in the upper blade piece  21 . At this time, the gap portion  60 , which allows the shaft portion  51  of the pull  50  to pass, can be formed between the rear mounting pillar  26  and the pawl body  30  as shown in  FIG. 3 . By deforming the slip-out preventing portions  27   a  of the fitting guide groove  27  plastically, the rear mounting pillar  26  can be prevented from escaping out from the rear end of the upper blade piece  21 .  
         [0115]     The gap portion  60  at a position where the rear end portion of the rear mounting pillar  26  makes contact with the slip-out preventing portion  27   a  has a maximum interval which allows the shaft portion  51  of the pull  50  to pass through between the rear mounting pillar  26  and the pawl body  30  as described above. Therefore, the rear mounting pillar  26  can be slid along the fitting guide groove  27 , so that it can be located at a position where the gap portion  60  is closed and at a position where the gap portion  60  is opened and whereby the gap portion  60  can be closed with the rear mounting pillar  26 .  
         [0116]     Now, the shaft portion  51  of the pull  50  is placed in the gap portion  60  as shown in  FIG. 3 . Then, when the shaft portion  51  of the pull  50  is slid from a bottom end of the pull guide face  21   e - 2  of the pull guide piece  21   e  on a side of the rear mounting pillar  26  to a top end thereof as shown in  FIG. 6 , the concave portion  32  of the pawl body  30  is lifted. At this time, the base end of the pawl body  30  presses and elastically deforms the compression coil spring  11  with the pin  12  in the pawl mounting portion  21   d  as a swinging center and then, the concave portion  32  of the pawl body  30  swings upward against an elastic force of the compression coil spring  11 . If the shaft portion  51  of the pull  50  surpasses a top end of the pull guide piece  21   e  against the elastic force of the compression coil spring  11 , it is inserted into the opening end of the concave portion  32  in the pawl body  30 .  
         [0117]     If the shaft portion  51  of the pull  50  is inserted into the opening end of the concave portion  32  in the pawl body  30 , the shaft portion  51  of the pull  50  is slid downwardly along the pull guide face  21   e - 1  of the pull guiding piece  21   e  at a side of the front mounting pillar  25 . When the pull  50  is slid, the base end of the pawl body  30  swings upward by the elastic force of the compression coil spring  11  with the pin  12  as the swinging center, and the concave portion  32  of the pawl body  30  swings downward with the pin  12  as the swinging center.  
         [0118]     At the same time when the shaft portion  51  of the pull  50  passes the front base end of the pull guide piece  21   e , the compression coil spring  11  is returned elastically to its original state with the pin  12  as a swing center. At this time, the pawl portion  31  of the pawl body  30  is automatically inserted into the pawl hole portion  21   f  in the upper blade piece  21  and the shaft portion  51  of the pull  50  is accommodated in the concave portion  32  of the pawl body  30  as shown in  FIG. 7 . Consequently, the shaft portion  51  of the pull  50  can be prevented from escaping out of the concave portion  32  of the pawl body  30  even before the gap portion  60  is closed by the rear mounting pillar  26 , because the pull guide piece  21   e  exists on a forward side of the slider with respect to the opening end of the concave portion  32  in the pawl body  30 .  
         [0119]     Next, the rear mounting pillar  26  is moved toward the front mounting pillar  25  along the fitting guide groove  27  in the upper blade piece  21  and brought into a contact with the positioning portions  21   g . With this condition, the ring-like holding portion  52  of the pull  50  is inserted striding the rear mounting pillar  26  so as to place the pull  50  entirely in a substantially horizontal state. By bringing the rear mounting pillar  26  into a contact with the positioning portion  21   g , the gap portion  60  is partially narrowed and then closed. At this gap closing position, the shaft portion  51  of the pull  50  can be prevented from escaping from the opening end of the concave portion  32  in the pawl body  30 .  
         [0120]     Next, as shown in  FIG. 8 , the pull holding body  40  is fitted into the front and rear mounting pillars  25 ,  26  over the pawl body  30  and the pull  50 . When the pull holding body  40  is fitted into the front and rear mounting pillars  25 ,  26 , the engaged portions  41   a ,  42   a  of the pull holding body  40  slide along the guide slope face of the engaging portions  25   d ,  26   d  of the front and rear mounting pillars  25 ,  26  while deforming elastically in an expanding direction and the engaged portions  41   a ,  42   a  pass a front end slop faces of the guide slope faces. At the same time, the engaged portions  41   a ,  42   a  of the pull holding body  40  are restored elastically in a contraction direction, so that the engaged portions  41   a ,  42   a  are engaged with the edge engaging faces of the engaging portions  25   d ,  26   d.    
         [0121]     At an insertion limit position of the pull holding body  40 , the lacking portions  44  in the pull holding body  40  fit and engage with the respective projecting portions  25   b ,  26   b  on the front and rear mounting pillars  25 ,  26  as shown in  FIG. 9 . When the top wall portion of the pull holding body  40  is accommodated in the front and rear mounting pillars  25 ,  26 , the top wall portion of the pull holding body  40  is kept flush with the top end faces of the front and rear mounting pillars  25 ,  26 . The bottom end faces of the right and left wing pieces  43 ,  43  of the pull holding body  40  shield and close a part of the operation space portion for operating a part of the pull  50  and the pawl body  30  in a state in which they are apart from the top face of the upper blade piece  21 . Consequently, the assembly of the slider  10  is completed.  
         [0122]     Despite such a simple structure in which the engaged portions  41   a ,  42   a  of the pull holding body  40  are caught by the engaging portions  25   d ,  26   d  of the front and rear mounting pillars  25 ,  26 , the gap portion  60  can be partially narrowed and closed when the pull holding body  40  is engaged with the slider body  20 . Further, this structure can be constructed as closing means for preventing the shaft portion  51  of the pull  50  from escaping out from the opening end of the concave portion  32  in the pawl body  30 .  
         [0123]     When the pull holding body  40  is fixed by engagement, the pawl body  30  and the pull  50  are integrated with each other so that they are not separable, thereby considerably improving the assembly performance and reliability and ensuring tractability. When mounting the pull  50  on the top face of the slider body  20 , the pull  50  and the pull holding body  40  can be assembled in order after the pawl body  30  is mounted on the top face of the slider body  20 . Thus, the pull  50  can be assembled on the top face of the slider body  20  after the pawl body  30  is mounted thereon by combinations of various kinds of shapes and colors and this assembly can be performed easily and stably by man power or with an automatic assembly machine. It is not necessary to provide the slider body  20  with any special structure member or associate complicated structure. Consequently, the slider  10  can be manufactured with a simple structure and manufacturing cost of the slider  10  can be reduced.  
         [0124]     For example, it is possible to prepare a slider body  20  loaded with a pawl body  30  and various types of pulls  50  and pull holding bodies  40  having different shapes or colors suitable for the slider body  20  separately. Consequently, after an order according to a request or a desire of a customer is received, various types of the pulls  50  can be installed on the slider body  20  mounting the pawl body  30 . As a result, components of the slider can be used effectively and the slider  10  having highly versatility is obtained so as to intensify the value of the slider  10  as a product.  
         [0125]     When releasing an engagement between the pawl portion  31  of the pawl body  30  and the engaging elements (not shown), first of all, the pull  50  assembled in parallel to the slider body  20  as shown in  FIG. 9  is lifted up with a hand. Then the shaft portion  51  of the pull  50  rises along the pull guide face  21   e - 1  on the side of the front mounting pillar  25  of the pull guide piece  21   e . As the pull  50  rises, the pawl body  30  swings forward with the shaft portion  51  of the pull  50  as a swinging center. When the pawl body  30  swings, the base end portion of the pawl body  30  presses and elastically deforms the compression coil spring  11  in a direction for releasing the engagement of the pawl portion  31  with an engaging element (not shown). When the shaft portion  51  of the pull  50  moves to the moving limit position of the pawl body  30 , the pawl portion  31  departs from the engaging element through the pawl hole portion  21   f  in the upper blade piece  21  as shown in  FIG. 8 , thereby releasing the engagement.  
         [0126]     Upon a releasing operation, the slider  10  can move freely to the side of the shoulder or the rear opening of the slider  10 . By moving the slider  10  freely, a zip teeth row (not shown) of a fastener chain can be engaged with each other or released to the right and left. If the pull  50  is released from the hand after this desired operation is completed, the pawl body  30  swings backward due to an elastic force of the compression coil spring  11 . When the pawl body  30  swings, the shaft portion  51  of the pull  50  descends along the pull guide face  21   e - 1  of the pull guide piece  21   e  and is restored to its original state elastically. At this time, the pawl portion  31  of the pawl body  30  is automatically inserted between the zip teeth row of the fastener chain through the pawl hole portion  21   f  in the upper blade piece  21 . Consequently, the pawl portion  31  of the pawl body  30  engages with the engaging element. With this engagement condition, the slider  10  is prevented from moving further and kept stopped.  
       Second Embodiment  
       [0127]     Next, another structure example of the slider  10  mounting the pawl body  30  will be described with reference to FIGS.  10  to  15 . FIGS.  10  to  15  show a second embodiment of the slider for the slide fastener with the automatic stopper of the present invention.  FIG. 10  is a perspective view showing a state in which components constituting the slider are disassembled. FIGS.  11  to  14  are longitudinal sectional views showing assembly steps of the slider and  FIG. 15  is a perspective view of the slider.  
         [0128]     In these Figures, points largely different from the first embodiment is that, as shown in  FIG. 12 , a gap portion  60  for allowing the shaft portion  51  of the pull  50  to pass through is formed between the rear mounting pillar  26  formed integrally with the top face at the rear portion of the upper blade piece  21  of the slider body  20  so as to stand upright and the pawl body  30  mounted on the front portion of the top face of the upper blade piece  21  so as to swing vertically and that closing means for preventing the pull  50  from escaping out from the opening end of the concave portion  32  in the pawl body  30  by narrowing and closing a part of the gap portion  60  when the pull holding body  40  is engaged with the front and rear mounting pillars  25 ,  26  is constructed on each of the right and left wall portions (wing pieces)  43 ,  43  of the pull holding body  40 .  
         [0129]     Such components as the front mounting pillar  25 , the pawl body  30 , the pull  50 , and the compression coil spring  11  are not different from the first embodiment except a part of structure of the slider body  20  shown in the drawings and the second embodiment is constructed of a similar structure. Thus, for the second embodiment, an upper blade piece  21  of the slider body  20 , the rear mounting pillar  26  on a single side and a pull holding body  40  will be described specifically. In the meantime, identical member names and reference numerals are given to members substantially same as those of the first embodiment. Therefore, detailed description of these members is omitted.  
         [0130]     A pair of front and rear mounting pillars  25 ,  26  are formed integrally on the top face of the upper blade piece  21  such that they stand upright for mounting the pull holding body  40  acting as a narrow transverse C shaped cover body, as shown in  FIG. 10 . This rear mounting pillar  26  comprises the rear supporting wall  26   a , the projecting portion  26   b , the step portion  26   c  and the engaging portions  26   d  like the first embodiment as shown in  FIG. 11 .  
         [0131]     What is different from the rear mounting pillar  26  of the first embodiment is that the rear mounting pillar  26  is fixed integrally in a immobile condition on the top face at the rear portion of the upper blade piece  21 . Further what is different from the rear mounting pillar  26  of the first embodiment is that a gap between the front face of the rear mounting pillar  26  and the pawl body  30  when mounting the pawl body  30  is expanded as shown in  FIG. 12  by forming a front wall of the rear mounting pillar  26  into a substantially flat plane as shown in  FIG. 11  without setting a length of the slider body  20  in back and forth directions unnecessarily longer. Therefore, an insertion of the shaft portion  51  of the pull  50  can be facilitated. Additionally, structures of the upper blade piece  21  of the slider body  20  and the rear mounting pillar  26  are simplified more than the first embodiment thereby leading to a further reduction in material cost, manufacturing cost and assembly cost.  
         [0132]     As shown in  FIG. 11 , the pawl body accommodating concave portion  21   b  extending from a rear base end of the front mounting pillar  25  to the rear mounting pillar  26  is formed as a placing face for the pawl body  30  in a central portion of the top face of the upper blade piece  21  without providing the pull guide pieces  21   e . The spring accommodating hole  21   c  for the compression coil spring  11  is made in a center of a front end of a bottom face of the pawl body accommodating concave portion  21   b . The rectangular pawl hole portion  21   f  which engages with/disengages from the pawl portion  31  of the pawl body  30  after the pawl body  30  is mounted is formed in a pierced manner adjacent to a front base end of the rear mounting pillar  26 . This pawl hole portion  21   f  communicates with the engaging element guide path  24 .  
         [0133]     According to the second embodiment, a specified interval is set between the respective mounting pillars  25  and  26  as shown in  FIG. 12  so as to form a sufficient space portion for accommodating a part of the shaft portion  51  of the pull  50  and the pawl body  30 . Therefore, during an assembly process before the pull holding body  40  is engaged with the respective mounting pillars  25 ,  26  after the pawl body  30  is accommodated in the pawl body accommodating concave portion  21   b  in the upper blade piece  21 , the gap portion  60  which allows the shaft portion  51  of the pull  50  to pass through can be secured sufficiently between the front face of the rear mounting pillar  26  and the opening end of the concave portion  32  in the pawl body  30 .  
         [0134]     As shown in  FIGS. 10 and 14 , the pull holding body  40  has the right and left wing pieces  43 ,  43  for covering and shielding a part of the space portion between the front mounting pillar  25  and the rear mounting pillar  26 . In the right and left wing pieces  43 ,  43 , right and left side walls  43   a ,  43   a  extend downward as shown in  FIGS. 10 and 13 . A front end face of each of the right and left side walls  43   a  is formed as a pull guide face  43   b  for guiding the shaft portion  51  of the pull  50  by its smooth circular curve as shown in  FIG. 13 .  
         [0135]     Existence of the pull guide face  43   b  enables the pull  50  to be guided from a front base end of the pull guide face  43   b  to the moving limit position of the pawl body  30  when the pull  50  is actuated. Thus, it is possible to exclude the pull guide pieces  21   e  projecting from the top face of the upper blade piece  21  as seen in the first embodiment. Because the pull guide pieces  21   e  on the upper blade piece  21  can be excluded, simplification in the slider structure and reductions in size and thickness thereof can be achieved.  
         [0136]     As shown in  FIG. 14 , the right and left side walls  43   a  of the right and left wing pieces  43  can be constructed so as to cover and close the gap portion  60 . The right and left wing pieces  43  can be formed in a substantially identical length to a distance between the front mounting pillar  25  and the rear mounting pillar  26  and further, front end portions of each of the right and left wing pieces  43  can be formed shorter than a vertical length of the wall portions  41 ,  42 .  
         [0137]     When the pull holding body  40  is engaged with the respective mounting pillars  25 ,  26 , bottom end faces of the right and left wing pieces  43  are apart from the top face of the upper blade piece  21 , forming a space portion which allows the shaft portion  51  of the pull  50  to move. The space surrounded by the rear face of the pull holding body  40  and the top face of the upper blade piece  21  turns to an operation space portion for operating the shaft portion  51  of the pull  50  and the pawl body  30  when the pull holding body  40  is engaged with the slider body  20 .  
         [0138]     According to the second embodiment, with the above-described structure, when the pull holding body  40  is engaged with the respective mounting pillars  25 ,  26  as shown in  FIG. 14 , the gap portion  60  can be covered and closed. Further, it is possible to construct the right and left wing pieces  43 ,  43  of the pull holding body  40  as the closing means which prevents the pull  50  from escaping from the opening end of the concave portion  32  in the pawl body  30 .  
         [0139]     Upon assembly of the slider  10  having the above-described structure, as shown in FIGS.  11  to  15 , the assembly procedure for the compression coil spring  11 , the pawl body  30  and the pull holding body  40  is not substantially different from that of the first embodiment. According to the structure of the slider  10  of the second embodiment, after the pawl body  30  is mounted on the top face of the upper blade piece  21  such that it is capable of swinging vertically, the shaft portion  51  of the pull  50  can be inserted into the gap portion  60  formed between the rear mounting pillar  26  and the pawl body  30  as shown in  FIGS. 12 and 13 . Consequently, the shaft portion  51  of the pull  50  can be inserted into the concave portion  32  in the pawl body  30  with the pawl body  30  placed and kept in a substantially vertical posture on the pawl body accommodating concave portion  21   b  of the upper blade piece  21 . Next, the ring-like holding portion  52  of the pull  50  is inserted transversing the front mounting pillar  25  and the pull  50  is entirely placed in a substantially horizontal posture.  
         [0140]     At this time, the gap portion  60  and the concave  32  in the pawl body  30  can secure a sufficient insertion space for the shaft portion  51  of the pull  50  without any interference by surrounding members as shown in  FIGS. 12 and 13 . For the reason, it is not necessary to move the pawl body  30  against an elastic force of the compression coil spring  11 . Therefore, not only an assembly with an automatic assembly machine can be carried out, but also the assembly with man power can be achieved easily and securely as the first embodiment. Further, productivity can be increased, thereby reducing manufacturing cost.  
         [0141]     Next, by a same operation as the first embodiment, the top wall portion of the pull holding body  40  is fitted to the front and rear mounting pillars  25 ,  26  such that it is accommodated inside the front and rear mounting pillars  25 ,  26  and the bottom end faces of the right and left wing pieces  43 ,  43  shield a part of the operation space portion for operating a part of the pull  50  and the pawl body  30  in a condition in which the bottom end faces thereof depart from the top face of the upper blade piece  21 . Then, the right and left side walls  43   a  of the right and left wing pieces  43  cover and close the gap portion  60 . Consequently, the assembly of the slider  10  is completed as shown in  FIG. 15 . In the meantime, operations for moving and stopping the slider  10  can be carried out by same operations as the first embodiment.  
       Third Embodiment  
       [0142]      FIG. 16  shows a third embodiment of the slider for the slide fastener with the automatic stopper of the present invention. Identical member names and reference numerals are given to substantially same members as the above-described embodiments. Therefore, a detailed description thereof is omitted.  
         [0143]     In  FIG. 16 , the reference numeral  13  denotes a modification of a urging means for the pawl body  30  applied to the present invention. In the slider shown here, the spring accommodating hole  21   c  and the compression coil spring  11  accommodated in the spring accommodating hole  21   c  are excluded and an end portion of a leaf spring  13  is supported by a top portion of a front face of the front mounting pillar  25  in a cantilevered state while the bottom end of the same leaf spring  13  presses a top face of the pawl body  30 . Consequently, the pawl portion  31  of the pawl body  30  can be always urged so as to project into the engaging element guide path  24  through the pawl hole portion  21   f  in the upper blade piece  21 . If comparing with the above-described respective embodiments, although the third embodiment has same operations and effects as those of the respective embodiments, simplification of the slider structure and reductions in size and thickness can be achieved easily.  
         [0144]     Although the pin  12  which supports the pawl body  30  rotatably is mounted in the pin supporting hole formed in the pawl body mounting portions  21   d ,  21   d  of the upper blade piece  21  and fixed on the top face of the upper blade piece  21  by crimping the pawl mounting portions  21   d  according to the respective embodiments, the present invention is not restricted to this example, and it can be fixed with conventionally known appropriate fixing means. For example, it is permissible to mount the pawl body  30  such that it is capable of swinging vertically by inserting the pin into a shaft hole provided in the front mounting pillar  26  and then fix the pin to the front mounting pillar  26  by crimping an exposed end portion of the pin.  
         [0145]     The above description has exemplified preferred embodiments and modifications and the present invention is accomplished if the rear mounting pillar  26  and/or the pull holding body  40  has the gap portion  60  and the closing means. Thus, needless to say, the object of the present invention can be achieved sufficiently by setting a shape and a size of the rear mounting pillar  26  or the pull holding body  40  appropriately in relation with other factors such as shapes and sizes of other components. Thus, naturally, the present invention is not restricted to the above-described embodiments and modifications and may be modified in various ways within a scope of a protection of the present invention.
