     Moreover, the discharge lid  3  is installed on the front end of the main body tube  51  and serves to expel liquid type cosmetic material pressed out by the piston  2  in accordance with the movement of the movable body  13 , from the front end of the main body tube  51  (see FIG.  1  and FIG.  2 ). Of course, the invention is not limited to this, and provided that it can be installed on the front end of the main body tube  51 , it is possible to use a brush, or the like, for example. 
     Moreover, the cap  4  is installed detachably on the front end tube section  51 a of the main body tube  51 , and serves to cover the coating member  6 , or the like (see FIG.  1 ).

     Below, more detailed descriptions of the respective constituent elements are given. 
     (1) Main Body  11   
     The main body  11  is formed with a female screw thread  11 a in the intermediate portion of the inner circumference thereof, which screws together with a male screw thread  13 a of a screw thread section of the movable body  13  inserted from the rear side of the main body  11 , and a collar section  11 b comprising a step section between the inner circumference of the intermediate portion and the inner circumference of the portions other than the intermediate portion is formed inside the main body  11  (see FIG.  1  and FIG.  2 ). 
     Specifically, the main body  11  comprises a main body tube  51  and a cylindrical member  52 , as illustrated in FIG.  1  and FIG.  2 . 
     The main body tube  51  is constituted by a circular cylindrical shaped member (see FIG.  1  and FIG.  2 ). 
     As described in  FIG. 1 , the main body tube  51  comprises a front end tube section  51 a having a smaller external diameter on the front side thereof, and a rear end tube section  51 b having a larger internal diameter on the rear end side thereof. 
     As this diagram shows, a ring-shaped projection  51 c is formed on the inner circumference of the main body tube  51  at a position of a prescribed length from the front end thereof, and a plurality of projecting ribs  51 e extending for a prescribed length in the axial direction are formed at equidistant intervals in the circumferential direction, at a position in the vicinity of a step section  51 d of the rear end tube section  51 b, and furthermore, a ring-shaped depression  51 f is formed in a position towards the rear end of the main body tube  51 . 
     On the other hand, as shown in  FIG. 1 , the cylindrical member  52  is inserted and disposed in a position towards is the step section  51 d inside the rear end tube section  51 b of the main body tube  51 . 
     As shown in  FIG. 3 , the cylindrical member  52  comprises a circular tube section  52 a forming a circular tube shape, and a collar section  11 b forming a step section formed integrally with the external circumference of the circular tube section  52 a. 
     As  FIG. 3  also shows, a female screw thread  11 a forming a tube side screw thread section is provided on the inner circumference of the circular tube section  52 a, centrally about the axis thereof. Moreover, as the diagram also shows, the rear end of the collar section  11 b is formed with a depressed ring-shaped groove  52 b formed in a ring shape, and a plurality of ratchet teeth  14 a facing towards the rear end and projecting in an inclined manner in one of the circumferential directions are provided at equidistant intervals in the circumferential direction on the bottom face of this ring-shaped groove  52 b. 
     Furthermore, as  FIG. 3  also shows, a plurality of projecting ribs  52 c extending in the axial direction are formed at equidistant intervals in the circumferential direction on the outer circumference of the collar section  11 b. 
     As illustrated in FIG.  1  and  FIG. 2 , this cylindrical member  52  is urged by a ratchet spring section  81 , described hereinafter, provided further to the rear end side thereof, and is coupled with the main body tube  51  in a non-rotatable fashion by means of the front end edge portion of the collar section  11 b abutting against the step section  51 d of the rear end tube section  51 b, whilst the respective projecting ribs  52 c of the collar section  11 b are positioned in between the respective plurality of projecting ribs  51 e formed in an longitudinal direction on the inner circumference of the main body tube  51 . 
     (2). Operating Member  12   
     As shown in  FIG. 1 , FIG.  2  and  FIG. 4 , the operating member  12  has a base  12 a on the rear end thereof, and is coupled to the rear end section of the main body  11  rotatably about the axis of the female screw thread  11 a. A spring presser  12 b forming a projecting section which projects further to the inner side than the front side of the inner circumference is provided intermittently in the circumferential direction on the rear side of the inner circumference of the operating member  12 . 
     As illustrated by the diagrams, the operating member  12  is constituted by an operating tube  61  and a shaft member  62 . 
     As shown in  FIG. 4 , the operating tube  61  is formed in a circular cylindrical shape. This operating tube  61  has a front end tube section  61 a having a smaller external diameter on the front end thereof, and a ring-shaped projecting section  61 b is provided on the outer circumference of this front end tube section  61 a. Moreover, as illustrated by the diagram, a plurality of projecting ribs  61 c extending for a prescribed length in the axial direction from the front end side are provided at equidistant intervals in the circumferential direction on the inner circumference of the operating tube  61 , and spring pressers  12 b are installed consecutively with the projecting ribs  61 c, extending until the base  12 a and projecting beyond the projecting ribs  61 c towards the central axis. 
     As shown in  FIG. 1 , FIG.  2  and  FIG. 4 , the front end tube section  61 a of the operating tube  61  is inserted inside the rear end tube section  51 b of the main body tube  51 , the step section  61 d of the front end tube section  61 a abuts with the rear end face of the main body tube  51 , and the ring-shaped projection section  61 b fits into the ring-shaped depression  51 f on the main body tube  51 , thereby coupling the operating tube  61  to the main body tube  51  in a mutually rotatable fashion. 
     On the other hand, as shown in FIG.  1  and  FIG. 2 , the shaft member  62  is provided so as to project to the front side from the base  12 a, and it is inserted inside the movable body  13  from the rear side of the movable body, slidably in the longitudinal direction and in a non-rotatable fashion. 
     As shown in FIG.  4  and  FIG. 5 , the shaft member  62  is installed in a standing position in such a manner that it faces towards the front end side from the middle of the base  12 a, and it has an approximately cross-shaped form. The shaft member  62  is formed integrally with the operating tube  61 , from the viewpoint of reducing the number of components and facilitating the assembly process, but it may also be formed as a separate member which is coupled by insertion fitting, screw fitting, or the like. 
     In other words, by means of a shaft member  62  of this kind, it is possible to transmit the rotational force of the operating member  12  to the movable body  13  by means of a composition wherein it is inserted into the movable body  13  from the rear side of the movable body, and hence it is possible to maintain the same dispensing amount whilst shortening the overall length, compared to a conventional movable body dispensing device. 
     Here, as illustrated in  FIG. 5 , the shaft member  62  comprises a tube side rotation stopping (preventing) section on the outer circumference thereof. In other words, the shaft member  62  is formed with a plurality of depression sections (in the present embodiment, four depression sections)  62 c having a recess shaped cross-section, by excavating respective positions at 90° intervals in the circumferential direction, in a recess shaped cross section, in addition to which, a plurality of projecting ribs (in the present embodiment, four projecting ribs)  62 a respectively projecting towards the outer side and extending in the longitudinal direction are formed on either side of the depression sections  62 c in the circumferential direction. Moreover, as  FIG. 5  also shows, the movable body  13  is provided with a movable body rotation halting (preventing) section on the inner circumference thereof. In other words, a plurality of grooves  13 b which fit together with the projecting ribs  62 a are formed on the inner circumference of the movable body  13 , and projecting ribs  72  are formed on either side of these grooves  13 b. The front end edges of the projecting ribs  72  of the movable body  13  form supported edges  13 c, constituting supported sections which are supported by the shaft member  62 . 
     Moreover, as also shown in  FIG. 5 , the projecting ribs  62 a of the shaft member  62  are constituted by projecting ribs which are slightly larger than the size of the grooves  13 b of the movable body  13 , in the region from the intermediate portion of the projecting ribs  62 a until the base end side thereof, in such a manner that the projecting ribs  62 a can be inserted inside the grooves  13 b of the movable body  13 , from the front end side until the intermediate portion of the projecting ribs  62 a, whilst further insertion thereof beyond this is prevented and the movable body  13  and the shaft member  62  are maintained in a prescribed relative position in the radial direction (thereby preventing divergence between the central axles of same). Step sections in the intermediate portion of the projecting ribs  62 a form supporting edges  62 b which constitute supporting sections for supporting the supported edges  13 c of the movable body  13 . The composition for preventing further insertion of the projecting ribs  62 a of the shaft member  62  inside the grooves  13 b is not limited to the step-shaped step sections according to the present embodiment, it also being possible to adopt projecting ribs having oblique faces, or the like, or to adopt projecting ribs having a collar section, or the like, and in short, the intermediate regions of the projecting ribs  62 a should be formed to a larger size than the front end sections thereof which are inserted inside the grooves  13 b, and they should also be formed to a larger size than the grooves  13 b. 
     Here, it is also possible to envisage a comparative composition wherein the shaft member is formed with a circular cross section, projecting ribs being provided at prescribed positions on the outer circumference of the circular, and slightly larger holes and grooves are formed on the movable body in a corresponding pattern to the shaft member provided with the projecting ribs, thereby maintaining the movable body and the shaft member in a prescribed relative position in the radial direction, but in the composition of this comparative example, there would be a large difference between the material thickness of the regions of the shaft member other than the projecting ribs (the shaft core portion) and the material thickness of the projecting ribs, and consequently, the surface of the moulded component is liable to have sink mark and in order to prevent such the sink mark, it is necessary to increase the moulding time, in addition to which, deformations, such as warping, bending, fracturing, or the like, become liable to occur due to the residual stress, in accordance with the non-uniform hardness caused by the non-uniform material thickness. 
     However, in the present embodiment, the composition of the projecting ribs  62 a of the shaft member  62  formed by excavating same in a recess shaped cross section in a plurality of locations involves inserting the region from the front end to the intermediate portion thereof inside the grooves  13 b of the movable body  13 , the portion from the intermediate portion to the base end side being formed to a larger size than the intermediate portion inserted into the grooves  13 b, but since the composition involves the formation of projecting ribs, the form of the shaft member  62  including the projecting ribs  62 a can be approximated to a composition wherein projecting ribs extend radially from the central axis of the shaft, as in a cross-shaped cross-section, for example, in such a manner that the material thickness of the shaft member  62  can be homogenized throughout the whole shaft member  62 , in comparison to the aforementioned comparative example. 
     (3) Movable Body  13   
     As shown in  FIG. 5 , the movable body  13  is formed in a cylindrical shape and a male screw thread  13 a is formed on the external circumference thereof. 
     More specifically, as this diagram also shows, the movable body  13  comprises two planar face sections  71  formed at mutually opposing positions on the external circumference of a cylindrical member and extending along the full length thereof, and a male screw thread  13 a formed extending in the axial direction on the curved surface except for the two planar face sections  71 . 
     Furthermore, as shown in  FIG. 5 , the internal diameter of the rear end side of the movable body  13  is a reduced diameter and a plurality of projecting ribs  72  extending in the axial direction are formed approximately equidistantly in the circumferential direction on the inner circumference of this rear end of reduced diameter. 
     As shown in  FIG. 1 , the movable body  13  is engaged slidably in the axial direction and in a non-rotatable fashion, with respect to the shaft member  62 , by means of the front end section of the male screw thread  13 a screwing together with the female screw thread  11 a on the inner circumference of the cylindrical member  52 , whilst the projecting ribs  62 a of the shaft member  62  forming a approximate cross shape are positioned between the projecting ribs  72 ,  72 , and in this state, the rear end faces of the projecting ribs  72  are disposed in the vicinity of the base end section of the shaft member  62 . 
     More specifically, as shown in the diagram, in this state, the shaft member  62  and the female screw thread  11 a on the cylindrical member  52  and ratchet teeth  14 a,  14 b are disposed in mutually overlapping positions in the same plane orthogonal to the axial direction. 
     (4) Ratchet  14   
     As illustrated in FIG.  3  and  FIG. 6 , the ratchet  14  comprises a set of ratchet teeth, in other words, the ratchet teeth  14 a on the cylindrical member  52 , and ratchet teeth  14 b and ratchet spring  14 c on the ratchet spring section  81 , described hereinafter, and it is used in order to restrict the movement of the movable body  13  in the forward direction or rearward direction. 
     More specifically, as these diagrams illustrate, the ratchet  14  comprises a cylindrical ratchet spring section  81  in which either one of the sets of ratchet teeth  14 a,  14 b, and the ratchet spring  14 c are formed in an integral fashion. As shown in FIG.  1  and  FIG. 2 , the ratchet spring section  81  is sandwiched between the collar section  11 b of the cylindrical member  52  forming a step section and the spring pressers  12 b of the operating tube  61  forming a projecting section, in such a manner that the shaft member  62  is able to penetrate through the inner side of the ratchet spring section  81  and thereby pass inside the movable body  13 . 
     In other words, according to the ratchet spring section  81  of this kind, it is possible for the shaft member  62  to penetrate through the inner side thereof and thereby pass inside the movable body  13 , and hence it is possible to maintain the same dispensing amount whilst shortening the overall length, in comparison with a conventional movable body dispensing device. 
     Of course, the ratchet spring section  81  is not limited to this and it is also possible for it to be provided sandwiched between the collar section  11 b of the cylindrical member  52  forming the step section and the inner portion of the operating member  12 , in such a manner that the shaft member  62  is able to penetrate through the inner side thereof and thereby pass inside the movable body  13 . In other words, it is also possible to use a ratchet spring section  81  which is sandwiched, for example, between the collar section  11 b of the cylindrical member  52  and the base  12 a of the operating member  12 , or the like. 
     More specifically, the ratchet spring section  81  is formed from synthetic resin, as illustrated in  FIG. 7 , and comprises a circular tube section  14 d formed in a circular tube shape, and a ratchet spring  14 c formed a circular tube shape provided consecutively to the rear end of the this circular tube section  14 d. 
     As the diagram shows, the circular tube section  14 d comprises a plurality of ratchet teeth  14 b, provided at equidistant intervals in the circumferential direction on the front end face thereof, which project in an inclined fashion in such a manner that face towards to the front end side and mesh with the ratchet teeth  14 a. Moreover, as shown in the diagram, a plurality of projecting ribs  14 e extending for a prescribed length in the axial direction are formed on the outer circumference of the circular tube section  14 d at equidistant intervals in the circumferential direction. Furthermore, as shown in this diagram, the ratchet spring  14 c comprises a slit  14 f cut out in a spiral fashion on the outer circumference thereof, in such a manner that the ratchet spring  14 c can be extended or compressed by means of this slit  14 f, thereby generating a force of impulsion. 
     As shown in  FIG. 1 , this ratchet spring section  81  is coupled in a non-rotatable manner to the operating tube  61 , by means of the ratchet spring  14 c being compressed between the collar section  11 b of the cylindrical member  52  and the spring pressers  12 b of the operating tube  61  and generating a force of impulsion in the longitudinal direction, the ratchet teeth  14 a,  14 b meshing together (the ratchet teeth  14 a,  14 a being positioned mutually between ratchet teeth  14 b,  14 b), and furthermore, the front end edge section of the collar section  11 b of the cylindrical member  52  abutting the step section  51 d of the rear end tube section  51 b, in which state, the respective projecting ribs  14 e of the circular tube section  14 d are positioned between the respective projecting ribs  61 c,  61 c of the operating tube  61 . 
     As described above, in the movable body dispensing device  1  of this kind, it is possible to transmit the rotational force generated by the operating member  12 , to the movable body  13 , by means of a shaft member  62  inserted slidably in the longitudinal direction in a non-rotatable manner inside the cylindrical shaped movable body  13 , and moreover, the shaft member  62  penetrates the inside of the ratchet spring section  81  to enable the movable body  13  to pass through. Further, the shaft member  62  penetrates through the female screw thread  11 a of the main body  11  which screws together with the male screw thread  13 a of the movable body  13 . 
     Consequently, according to the movable body dispensing device  1  of this kind, the shaft member  62  forming the tube side rotation preventing section and the female screw thread  11 a of the main body  11  forming the tube side screw thread section overlap mutually in the same plane orthogonal to the axial direction, and furthermore, the shaft member  62  and the ratchet teeth  14 a,  14 b overlap mutually in the same plane orthogonal to the axial direction, thereby making it possible to shorten the overall length compared to the prior art, whilst maintaining the same dispensing amount, and hence allowing satisfactory downsizing of the eventual product. 
     Moreover, according to the movable body dispensing device  1 , since the shaft member  62 , the female screw thread  11 a and the ratchet teeth  14 a,  14 b overlap mutually in the same plane orthogonal to the axial direction, further downsizing can be achieved. 
     Furthermore, according to the movable body dispensing device  1 , since the intermediate portions of the projecting ribs  62 a (the region from the intermediate portion to the base end in the present embodiment) are constituted by projecting ribs which are larger than the size of the grooves  13 b, in such a manner that the region of the projecting ribs  62 a from the front end side to the intermediate portion thereof can be introduced inside the grooves  13 b of the movable body  13 , and further insertion beyond this is prevented, the movable body  13  and the shaft member  62  being maintained in prescribed relative positions in the radial direction, then the projecting ribs does not need to be made longer than necessary, thereby making it possible to avoid unnecessary forming processes. 
     In addition, in a movable body dispensing device  1  of this kind, since the aforementioned projecting ribs  62 a of the shaft member  62  are formed by excavating a plurality of locations in a recess shaped cross section, it is possible to approximate the shape of the shaft member  62  including the projecting ribs  62 a to a composition wherein the projecting ribs extend radially from the central axis of the shaft, thereby making it possible to homogenize the material thickness throughout the whole shaft member  62 . 
     As a result, the sink mark of the surface of the moulded components can be prevented, without lengthening the moulding time, and furthermore, an even hardness is achieved and hence deformations, such as warping, bending, fracturing, or the like, are not liable to occur. 
     In this way, according to the movable body dispensing device relating to the present invention, it is possible to shorten the overall length of the device in comparison to the prior art, whilst maintaining the same dispensing amount, thereby making it possible to compactify manufactured products satisfactorily.
