BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT  
       [0001]     The present invention relates to a holding tool for an elongated member, and in particular, it relates to a holding tool for temporarily fastening onto a rod-shaped body or cord-shaped body when conveying in a subassembly state.  
         [0002]     For example, in an electric sliding door of an automobile, the electric motor and the door are linked by a drive transmission cable in order to drive the door to open and close by the rotary force of the electric motor. Also, a holding tool having a ring-shaped part for running the cable therethrough is used in order to hold the cable against the door or vehicle body with a prescribed space therebetween.  
         [0003]     Meanwhile, in order to simplify parts management on the automobile assembly line, a drive device subassembly including the electric motor and the cable is conveyed in a state that a holding tool is pre-attached to the cable. At this time, it is necessary to temporarily fasten the holding tool so that the tool does not move greatly from a prescribed position of the cable, and conventionally, adhesive tape has been used as this temporary fastening means.  
         [0004]     However, with this temporary fastening means of the prior art, the operation of affixing adhesive tape cut to a suitable length and the operation of discarding the peeled-off tape are necessary. Because these operations are wasted operations that do not contribute at all to automobile manufacturing, improvement has been anticipated.  
         [0005]     This invention has been made to solve such inconvenience of the prior art, and it is an object of the invention to provide a holding tool for rod-shaped body or cord-shaped body that can easily perform temporary holding on a held member and moving and holding to a proper position during assembly.  
         [0006]     Further objects and advantages of the invention will be apparent from the following description of the invention.  
       SUMMARY OF THE INVENTION  
       [0007]     In order to solve such problem, in a first aspect of the present invention, the holding tool for rod-shaped member or cord-shaped member (for example cable) comprises a part for coupling (clip) on an attachment receiving body (for example vehicle body), a first holding part for holding a rod-shaped or cord-shaped member comparatively tightly, and a second holding part for holding the held member with a prescribed space therebetween, and a gap in which the held member is capable of moving is opened between the first holding part and the second holding part. By this, after the held member is temporarily fastened by the first holding part and is conveyed, and is assembled into the target object, the held member can be moved in the second holding part with a space therebetween and can be held in the proper position.  
         [0008]     Also, in a second aspect of the present invention, the first and second holding parts are formed between a movable part and a fixed part in which each one end is connected by means of a hinge and the other end has an interlocking means (protruding piece, hook ). In a third aspect of the invention, the first holding part has a restraining piece which is elastically deformed toward a direction widening the gap when a prescribed force is applied, and in a fourth aspect of the invention, the first holding part has a raised line in a direction orthogonal to the axial line of the held member.  
         [0009]     By the present invention as such, because temporary fastening of the holding tool onto the held member and moving to the proper position during assembly can be performed easily, wasted operations are eliminated, and a contribution can be made to the improvement of productivity. In particular, the attachment of the holding tool onto the held member can be easily made by making the first and second holding parts capable of opening and closing as a construction formed of a fixed part and a movable part with the respective ends connected by a hinge. Thus, temporary fixing and holding in a state when external force is not applied are increased by providing a restraining piece that is elastically deformed when a prescribed force is applied, and prevention of shifting on the axial line of the held member can be assured by the raised line in the direction orthogonal to the axial line of the held member.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0013]     The present invention is explained in detail below based on the attached drawings.  
         [0014]      FIG. 1  is a perspective view showing the entirety of a holding tool for a cable according to the present invention. This holding tool  1  is integrally formed with a synthetic resin material having elasticity. The holding tool  1  includes a movable part  3  having a protruding piece  2  which is roughly arrowhead-shaped in cross-sectional shape formed on one end, a fixed part  5  having a hook  4  which elastically couples with the protruding piece  2  formed on one end, and a thin hinge  6  for connecting the movable part  3  and the fixed part  5 . Also, a clip  7  which elastically couples onto an attachment receiving body, for example an automobile body, is integrally formed on the fixed part  5 . Also, when the movable part  3  is joined to the fixed part  5  by interlocking the protruding piece  2  and the hook  4 , as shown in  FIG. 2 , the first holding part  10  which can hold the cable  9  covered by an outer tube  8  comparatively tightly, and the second holding part  11  which can hold the cable  9  covered by the outer tube  8  with a prescribed space therebetween (comparatively loosely), are defined between the movable part  3  and the fixed part  5 .  
         [0015]     A semicircular restraining piece  12  which corresponds to the external contour of the outer tube  8  is formed on a part of the movable part  3  forming a part of the first holding part  10 . This restraining piece  12  is formed by forming a square bracket-shaped cut  13  near the hinge  6  of the movable part  3 , and it is made to have an elastic deformation. Also, a raised line  14  in the direction orthogonal to the axial line of the cable  9  is formed on a part of the fixed part  5  forming a part of the first holding part  10 .  
         [0016]     The clip  7 , which is integrally formed on the fixed part  5 , comprises a leg part  15  which projects out from the fixed part  5 , and a pair of elastic locking pieces  16  which extends to widen in a V shape from the free end of that leg part  15 , and has an arrowhead shape. The space between the free ends of the pair of elastic locking pieces  16  is made capable of contracting elastically. Also, a plate spring part  17  is formed on the base of the leg part  15 .  
         [0017]     As shown in  FIG. 1 , the cable  9  is laid near the hinge  6  in a state that the movable part  3  is opened, and next the movable part  3  is closed and the protruding piece  2  is coupled to the hook  4 . Here, because a semicircular restraining piece  12  is formed in a part of the first holding part  10  on the side of the movable part  3 , the cable  9  is held comparatively tightly in the first holding part  10  in conjunction with the raised part  14  formed on the side of the fixed part  5  biting into the outer tube  8  (see  FIG. 2 ). Accordingly, the cable  9  is temporarily fastened securely in the first holding part  10  as long as external force is not applied, and shifting during conveying is prevented.  
         [0018]     In this state temporarily fastened to the cable  9 , after the holding tool  1  is coupled to the vehicle body  18  by inserting the clip  7  into a hole  19  formed on the vehicle body  18 , when a prescribed force is applied to the cable  9 , the cable  9  is shifted from the temporarily fastened position to the actual use position inside the second holding part  11 , because the restraining piece  12  is elastically deformed outward and the gap G between the first holding part  10  and the second holding part  11  becomes wider. The cable  9  can be moved easily in the direction orthogonal to the axial line of the cable  9 , that is, toward the large-diameter second holding part  11  (see  FIG. 3 ).  
         [0019]     According, the holding tool  1  which is temporarily fastened to the cable  9  does not shift during conveying of the drive device subassembly, and after attaching the drive device to the vehicle body, the cable  9  is moved to the second holding part  11 , i.e. the proper holding position. The cable  9  can be held with a prescribed space loosely.  
         [0020]     The holding tool pertaining to the present invention has a temporary fastening function that can be removed comparatively easily, and it is useful for holding a flexible cable, as well as rods and electric wire.  
         [0021]     The disclosure of Japanese Patent Application No. 2004-243967 filed on Aug. 24, 2004 is incorporated in the application.  
         [0022]     While the invention has been explained with reference to the specific embodiments, the explanation is illustrative and the invention is limited only by the appended claims.
