In addition, the sheet winding device 10 may be used as a component part of a tonneau cover device that divides a vehicle space and a luggage compartment.

<Sheet take-up device>
First, an outline of the sheet winding device 10 will be described. The sheet winding device 10 includes a sheet-like member 12, a winding shaft 20, terminal members 25 and 30, a casing 40, and a rotation urging unit 50 (see FIG. 3).

  The sheet-like member 12 is a flexible sheet-like member formed by cutting, sewing or the like of a cloth material, a mesh-like cloth material, a resin sheet or the like (see FIG. 1). The sheet-like member 12 is formed in a shape and size according to the application, and in this case, a shape and size capable of partially or entirely shielding the window 11. Further, here, the sheet-like member 12 is formed in a shape in which the width dimension gradually decreases from the storage-side end portion toward the drawer-side end portion. Further, a rod-like drawing member 29 for drawing operation may be provided at the drawing side end of the sheet-like member 12.

  The winding shaft 20 is a portion that winds up the sheet-like member 12, and is formed in a long cylindrical shape (here, a cylindrical shape) (see FIG. 3). As for this winding shaft 20, the edge part of the sheet-like member 12 is attached to the outer peripheral part along the center axis direction. Further, the inner peripheral portion of the winding shaft 20 is formed in a shape in which concave portions and convex portions extending along the central axis direction are alternately arranged in the circumferential direction.

  Terminal members 30 and 25 are fixed to the longitudinal end of the winding shaft 20 (see FIG. 4). The terminal members 30 and 25 are fitted into both end portions of the winding shaft 20. Here, the terminal members 30 and 25 are formed in a bearing shape including a cylindrical inner peripheral surface. The terminal members 30 and 25 have a main body 31 or 26 and an overhang 38 or 28 (see FIGS. 4 and 5).

  The main body portions 31 and 26 are portions that are fitted inside the winding shaft 20. The outer peripheral portion of the main body portion 31 is formed in a shape corresponding to the inner peripheral portion of the winding shaft 20 in which parallel convex portions and concave portions extending linearly are alternately arranged in the circumferential direction. ing. Thereby, the terminal members 30 and 25 fitted in the winding shaft 20 are fixed to the winding shaft 20 so as not to be relatively rotatable around the central axis.

  In addition, the overhang portions 38 and 28 are formed in a hook-like shape that protrudes to the outer peripheral side at the proximal ends in the central axis direction of the main body portions 31 and 26. The overhang portions 38 and 28 come into contact with the end of the take-up shaft 20 from the central axis direction in a state where the main body portions 31 and 26 are fitted inside the take-up shaft 20 (see FIG. 5).

  In addition, about the terminal members 30 and 25, a more detailed shape is explained in full detail later.

  The casing 40 includes a casing body 42 and side covers 44a and 44b (see FIG. 3). The casing main body 42 has an internal space in which the winding shaft 20 around which the sheet-like member 12 is wound can be accommodated, and the sheet-like member wound around the winding shaft 20 with the internal space communicating with the outside. A slit is formed so that 12 can be pulled out. The side covers 44 a and 44 b are portions that block the openings at both ends of the casing body 42. The side covers 44a and 44b have rotation support portions 45a and 45b, respectively.

  The rotation support portions 45a and 45b respectively support the end members 30 and 25 so as to be relatively rotatable around the central axis of the winding shaft 20 from one side in the inner and outer directions of the winding shaft 20 (FIGS. 4 and 5). reference). Here, the rotation support portions 45 a and 45 b are formed in a shaft shape including a columnar outer peripheral surface, and are inserted inside the terminal members 30 and 25. Here, the diameters of the rotation support portions 45a and 45b are set smaller (in this case, slightly smaller) than the inner diameters of the terminal members 30 and 25.

  The rotation urging unit 50 urges the winding shaft 20 to rotate in the direction in which the sheet-like member 12 is wound around the casing 40. Here, the rotation urging unit 50 is a coil spring. The rotation urging portion 50 is disposed along the central axis direction inside the winding shaft 20. Further, one end of the rotation urging portion 50 is fixed to the tip of the rotation support portion 45 b of the side cover 44 b, and the other end is fixed to the inner peripheral portion of the winding shaft 20. In FIG. 3, the other end of the rotation urging portion 50 is fixed to a fixing portion 24 that is fixed so as not to rotate relative to the inner peripheral portion of the winding shaft 20.

  A sound insulation tube 55 for sound insulation may be disposed between the rotation urging portion 50 and the winding shaft 20.

<Terminal member>
Here, the description will be given focusing on one terminal member 30 (see FIG. 6). The terminal member 30 is provided with a configuration that suppresses rattling between the terminal member 30 and the rotation support portion 45a. That is, the rotation support portion 45a is manufactured to have a diameter smaller than the inner diameter of the terminal member 30 in order to support the terminal member 30 so as to be relatively rotatable around the central axis in a state where the rotation support portion 45a is fitted into the terminal member 30. . For this reason, depending on the combination of the terminal member 30 and the rotation support portion 45a, there may be a gap between the two within the error range set at the time of design. Therefore, a pressing portion that presses the other in the inner and outer directions of the winding shaft 20 is partially provided in one of the terminal member 30 and the rotation support portion 45 a in the circumferential direction of the winding shaft 20. Note that the terminal member 30 may be integrally formed by injection molding or the like of a synthetic resin material or the like.

  Here, a pressing portion 34 that presses the rotation support portion 45 a in the inner and outer directions of the winding shaft 20 is formed on the terminal member 30. The pressing portion 34 is partially provided in the circumferential direction of the terminal member 30. The pressing portion 34 includes an elastic deformation portion 36 that can be elastically deformed in the inner and outer directions of the terminal member 30 and a protrusion portion 35 that protrudes from the outer peripheral portion of the elastic deformation portion 36 toward the outer peripheral side. And the protrusion part 35 elastically deforms the elastic deformation part 36 to an inner peripheral side by contact | abutting to the inner peripheral part of the winding shaft 20, in the state in which the terminal member 30 was inserted in the winding shaft 20. FIG. In other words, the elastic deformation portion 36 protrudes from the cylindrical inner peripheral surface of the main body portion 31 toward the inner peripheral side. Thereby, the pressing part 34 presses the rotation support part 45a inserted inside the terminal member 30. In addition, it is preferable that three or more pressing portions 34 are formed at equal intervals in the circumferential direction of the terminal member 30, and here three are formed (see FIG. 8).

  The elastic deformation portion 36 occupies a part in the circumferential direction of the main body portion 31. Here, the elastic deformation part 36 is provided in the position of the convex part of the main-body part 31, and is formed in the shape which has the outer surface and inner surface of the main-body part 31, and the same outer surface and inner surface. The elastic deformation portion 36 is formed so as to be elastically deformable in the inner and outer directions of the terminal member 30 by setting the material (material of the terminal member 30), the thickness, and the like.

  The protruding portion 35 is formed in a shape that protrudes from the outer peripheral portion of the elastically deforming portion 36 to the outer peripheral side. A portion of the protrusion 35 on the distal end side in the central axis direction of the main body 31 is formed in a shape in which the protrusion dimension toward the outer peripheral side gradually increases as it approaches the proximal end from the distal end. The virtual circle connecting the outer peripheral side ends of the plurality of protrusions 35 is set larger (slightly larger here) than the inner diameter of the winding shaft 20 (the diameter of the virtual circle connecting the plurality of recesses).

  The main body 31 is provided with a retaining portion 32 for retaining the terminal member 30 from the winding shaft 20 in addition to the protruding portion 35 (see FIGS. 6 and 7). The retaining portion 32 is formed in a shape protruding from the outer peripheral end of the convex portion toward the outer peripheral side. More specifically, the retaining portion 32 is formed from the proximal end portion of the main body portion 31 along the central axis direction of the main body portion 31 to the middle portion in the central axis direction. Here, the retaining portions 32 are formed at intervals of a plurality of convex portions in the circumferential direction (see FIG. 8). An imaginary circle connecting the outer peripheral side ends of the plurality of retaining portions 32 is set larger (here, slightly larger) than the inner diameter of the winding shaft 20.

  With respect to the relationship between the protrusion 35 and the retaining portion 32, the protrusion 35 may have a larger protrusion dimension toward the outer periphery than the retaining portion 32. Here, every three protrusions 35 are provided on the same protrusion in the circumferential direction with respect to the plurality of protrusions and every other protrusion 32 with respect to the plurality of retaining portions 32. Here, the protrusion 35 is provided at a position closer to the tip than the retaining portion 32 in the central axis direction of the main body 31.

  In the circumferential direction of the terminal member 30, a slit 33 extending along the central axis direction of the terminal member 30 is formed in at least one side portion of the pressing portion 34 of the main body portion 31. Here, the slits 33 are formed on both sides of the pressing portion 34 in the circumferential direction of the terminal member 30. That is, the protrusion 35 is formed in the extending range of the slit 33 in the central axis direction of the terminal member 30 and is positioned between the pair of slits 33 in the circumferential direction. The slit 33 is formed in the recess of the main body 31.

  Further, in the relationship between the protrusion 35 and the slit 33, the protrusion 35 is formed at a position nearer to one end side from the center of the slit 33 in the central axis direction of the terminal member 30. Here, the protrusion 35 is provided at a position on the front end side in the central axis direction of the main body 31 from the center of the slit 33 in the central axis direction of the main body 31. When the terminal member 30 is fitted into the winding shaft 20, the base end side portion (the central portion in the extending direction of the slit 33) of the elastic deformation portion 36 is more elastically deformed to the inner peripheral side. Since the protrusion 35 is possible, the inclined portion contacts in a posture along the inner peripheral portion of the winding shaft 20. That is, the protrusion 35 is interposed between the elastic deformation portion 36 and the winding shaft 20 in a wedge shape. The elastic deformation portion 36 that has been elastically deformed to the inner peripheral side receives a force for elastic return to the original shape over almost the entire inclined portion.

<Assembly>
Next, assembly of the terminal member 30 will be described. As for the terminal member 30, when the main-body part 31 is inserted inside the winding shaft 20, the inclination part of each projection part 35 contact | abuts to the inner peripheral part of the edge part of the winding shaft 20 (refer FIG. 10). When the terminal member 30 is further inserted, the inclined portion of the protrusion 35 is pushed into the inner peripheral side while being in sliding contact with the inner peripheral portion of the winding shaft 20, and the elastic deforming portion 36 is elastically deformed, whereby each pressing portion 34. Projects to the inner peripheral side (see FIGS. 11 to 13). At this time, since the protrusion 35 is formed at a position on the tip side from the center of the slit 33 in the central axis direction of the main body 31, when the protrusion 35 is pushed into the inner peripheral side, A portion near the center in the extending direction of the slit 33 that is more easily elastically deformed is elastically deformed to the inner peripheral side larger than the protrusion size of the protrusion 35. As described above, the pressing portion 34 projects from the cylindrical inner peripheral surface of the main body portion 31 toward the inner peripheral side.

  When the terminal member 30 is inserted to a position where the overhang portion 38 contacts the end portion of the take-up shaft 20, the retaining portion 32 is pushed inside the end portion of the take-up shaft 20. Thereby, the terminal member 30 is prevented from coming off from the winding shaft 20. Further, the protrusion 35 is pressed against the inner peripheral portion of the winding shaft 20 by the force with which the pressing portion 34 attempts to return to its original shape. Thereby, the state in which the terminal member 30 is fitted in the winding shaft 20 can be more reliably maintained.

  Next, the rotation support portion 45 a is inserted inside the terminal member 30 fitted into the end portion of the winding shaft 20. When the rotation support portion 45 a is inserted inside the terminal member 30, the rotation support portion 45 a comes into contact with each pressing portion 34 (elastic deformation portion 36) projecting to the inner peripheral side of the main body portion 31. When the rotation support portion 45a is further inserted, the pressing portion 34 is bent outward by the rotation support portion 45a (see FIG. 14). In other words, the rotation support part 45a pushes the pressing part 34 bent toward the inner peripheral side back to the outer peripheral side. In this state, each pressing portion 34 presses the rotation support portion 45a toward the inner peripheral side by a force that maintains the shape bent toward the inner peripheral side.

  As described above, since the central portion of the slit 33 in the central axis direction of the main body portion 31 is bent larger than the protrusion size of the protrusion portion 35 toward the inner peripheral side, the pressing portion 34 bends toward the outer peripheral side at this central portion. easy. That is, the pressing part 34 presses the rotation support part 45a with a weaker force than when the rotation support part 45a is inserted into the terminal member 30 by being elastically deformed so as to crush the protruding part 35. For this reason, the rotation operation around the central axis of the terminal member 30 with respect to the rotation support portion 45a becomes smoother. Further, even if there is an error in the diameter of the rotation support part 45a, the pressing part 34 bends by absorbing the error.

  Further, in this state, the rotation support portion 45a is pressed toward the inner peripheral side by a plurality of pressing portions 34 provided at equal intervals in the circumferential direction, so that the central axis approaches the central axis of the winding shaft 20. The winding shaft 20 is supported in a state (see FIG. 15).

  The terminal member 30 has been described so far, but the terminal member 25 also has a configuration in which a pressing portion is formed from the viewpoint of suppressing rattling with the rotation support portion 45b. preferable. But the press part may be formed only in any one of the terminal members 30 and 25. FIG.

  The tip end of the rotation support portion 45a is formed in a substantially hemispherical shape. Correspondingly, the terminal member 30 is formed in a non-penetrating type having a dome-shaped (substantially hemispherical) tip end in the central axis direction. Yes. The rotation support portion 45 a is inserted inside the cylindrical inner peripheral surface of the terminal member 30. On the other hand, since one end portion of the rotation urging portion 50 fixed to the inner peripheral portion of the winding shaft 20 is fixed to the rotation support portion 45b, the terminal member 25 can be inserted through the rotation support portion 45b. It is formed in a penetration type that penetrates in the central axis direction. The rotation support portion 45 b is inserted inside the cylindrical inner peripheral surface of the terminal member 25.

<Effect>
According to the sheet winding device 10 and the terminal member 30 according to the above embodiment, the terminal member 30 fixed to the end of the winding shaft 20 by the rotation support portion 45a is relatively rotated around the central axis of the winding shaft 20. Since it is supported as possible, when the take-up shaft 20 is rotated, the sheet-like member 12 attached to the outer periphery thereof can be taken up. In addition, since the rotation support portion 45a is pressed in the inner and outer directions of the winding shaft 20 by the pressing portion 34 formed on a part of the terminal member 30 formed with the cylindrical inner peripheral surface, the terminal member 30 and the rotation support portion Shaking between 45a can be suppressed.

  Moreover, since the press part 34 is formed in the terminal member 30, the rattling between the terminal member 30 and the rotation support part 45a can be suppressed by the change of a smaller structure.

  Further, the pressing portion 34 partially provided in the circumferential direction of the terminal member 30 is elastically deformable portion 36 that can be elastically deformed in the inner and outer directions of the terminal member 30, and projects from the elastically deformable portion 36 to the outer peripheral side to be wound up A protrusion 35 is formed that elastically deforms the elastic deformation portion 36 toward the inner peripheral side by contacting the inner peripheral portion of the shaft 20. For this reason, the pressing portion 34 in which the projection 35 abuts on the inner peripheral portion of the winding shaft 20 is bent toward the inner peripheral side and presses the rotation support portion 45 a inserted in the terminal member 30. Thereby, shakiness between the terminal member 30 and the rotation support part 45a can be suppressed with a simpler configuration.

  Moreover, since the slit 33 extended along the center axis direction of the terminal member 30 is formed in the at least one side of the press part 34, the press part 34 is easy to bend to an inner peripheral side.

  Moreover, since the slit 33 is formed in the both sides of the press part 34 in the circumferential direction of the terminal member 30, the press part 34 can be easily bent by the rotation support part 45a side. In addition, since only the pressing portion 34 can be bent intensively, a larger amount of bending can be secured, and the winding shaft 20 of the terminal member 30 can be minimized while minimizing bending toward the inner peripheral side of other portions. The insertion state with respect to can be more reliably maintained.

  In addition, since the protruding portion 35 is formed with an inclined portion in which the protruding dimension gradually increases from the distal end side toward the proximal end side at the distal end side portion of the main body portion 31, the terminal member 30 with respect to the winding shaft 20. Insertion work can be performed more smoothly.

  In addition, since the protrusion 35 is formed at a position that is closer to one end side from the center in the extending direction of the slit 33, a margin that can be pushed back to the outer peripheral side can be provided in the central portion that is most likely to bend. At the same time, even with a small projection size, the central portion can be deflected more than the projection size. Thereby, the terminal member 30 can be supported by the rotation support part 45a corresponding to the clearance gap between the winding shaft 20 and the main-body part 31 of the terminal member 30 flexibly.

  Further, here, the protrusion 35 is formed at a position closer to the distal end side than the center of the slit 33 in the central axis direction of the terminal member 30, so that the protrusion dimension gradually increases from the distal end side toward the proximal end side. The inclined portion of the portion 35 contacts the inner peripheral portion of the winding shaft 20 as a whole. As a result, the entire inclined portion of the protrusion 35 receives the force to elastically return to the original shape of the elastic deformation portion 36 that has been elastically deformed toward the inner peripheral side, and the state where the pressing portion 34 is bent is stabilized. Can be maintained.

  Further, since three or more pressing portions 34 are formed at equal intervals in the circumferential direction of the terminal member 30, the winding shaft 20 to which the terminal member 30 supported by the rotation support portion 45a is fixed is smoothly rotated. be able to. Moreover, since the three press parts 34 are formed here, the stable axial support state can be maintained with fewer press parts 34, and the manufacturing process of the terminal member 30 can be simplified.

<Modification>
Up to now, the example in which three pressing portions 34 are provided at equal intervals in the circumferential direction of the terminal member 30 has been described, but the pressing portions 34 may be provided in a plurality of four or more, and are different from each other. It may be provided at intervals. However, from the viewpoint of smoothly supporting the terminal member 30 by the rotation support portion 45a, the central axes of the rotation support portion 45a and the terminal member 30 should be as close as possible (more preferably coincident). That is, it is preferable that at least one pressing portion 34 is provided in each of three regions obtained by dividing the terminal member 30 into three equal parts in the circumferential direction. Even if only one or two pressing portions 34 are provided, the effect of suppressing rattling between the terminal member 30 and the rotation support portion 45a can be obtained.

  Moreover, although the projection part 35 has been described in the example where it is formed at a position closer to the distal end side than the center of the slit 33 in the central axis direction of the terminal member 30, the projection part 35 has a base end from the center of the slit 33. It may be formed at a position close to the side.

  In the above description, the slits 33 are formed on both sides of the pressing part 34. However, the slits 33 may be formed only on one side of the pressing part 34 or may be omitted. Also good. However, from the viewpoint of ease of bending of the pressing portion 34, the slit 33 is preferably formed. Further, when the slit 33 is formed on one side of the pressing portion 34 or when the slit 33 is omitted, the material, thickness, etc. are set so that the elastic deformation portion 36 continuous with the main body portion 31 can be elastically deformed. Good.

  Moreover, although the elastic deformation part 36 has been described so far in the example extending along the central axis direction of the terminal member, the elastic deformation part is formed so as to extend along the circumferential direction. Also good. In this case, the slit may be formed to extend along at least one side (preferably both sides) of the pressing portion along the circumferential direction of the terminal member in the central axis direction of the terminal member.

  According to this structure, the elastic deformation part which contacts the outer peripheral surface of the rotation support part 45a. Since it extends in the circumferential direction of the main body 31 in the same direction as the relative rotation direction between the terminal member 30 and the rotation support portion 45a, the rotation of the winding shaft 20 relative to the rotation support portion 45a can be made smoother. .

  Further, like the terminal member 130 shown in FIGS. 16 to 20, the slit 133 may extend to the base end portion of the main body portion 131 and may be formed in a shape penetrating the protruding portion 138. And the base end part in the central-axis direction of the terminal member 130 is connected by the overhang | projection part 138. FIG. In other words, the pressing portion 134 has an elastic deformation portion 136 that is formed longer in the central axis direction of the main body portion 131 and is easily elastically deformed in the inner and outer directions.

  When the terminal member 130 is inserted into the end portion of the winding shaft 20, the elastic deforming portion 136 is elastically deformed to the inner peripheral side by the protrusion 35 coming into contact with the inner peripheral portion of the winding shaft 20. . Here, in particular, a portion of the elastic deformation portion 136 near the center in the central axis direction of the main body 131 is largely elastically deformed to the inner peripheral side. When the rotation support portion 45a is inserted into the terminal member 130, the pressing portion 134 protruding to the inner peripheral side is pushed back to the outer peripheral side. In this state, the pressing part 134 presses the rotation support part 45a to the inner peripheral side by a force that tries to protrude to the inner peripheral side.

  According to the terminal member 130 according to this configuration, since the slit 133 can be made longer in the central axis direction of the main body portion 131, the pressing portion 134 can be flexed more easily and can be contacted with the rotation support portion 45a. Can be increased. Thereby, rattling between the terminal member 130 and the rotation support part 45a can be suppressed, and the winding shaft 20 can be rotated more smoothly.

  16 shows an example in which the slits 133 are formed on both side portions of the pressing portion 134. However, the present invention is not limited to this case, and each may be formed on one side portion of the pressing portion 134. Moreover, although the non-penetrating type terminal member 130 is shown in FIG. 16, the terminal member may be formed in a penetrating type.

<First Modification>
Next, the terminal member 230 which concerns on a 1st modification is demonstrated (refer FIGS. 21-24). A portion different from the terminal member 30 according to the first embodiment in the terminal member 230 according to the first modification is a portion related to the pressing portion 234. The same components as those of the terminal member 30 are denoted by the same reference numerals and description thereof is omitted.

  The pressing portion 234 is formed in a cantilever shape in which one end portion in the extending direction of the slit 233 (a portion on the base end side in the central axis direction of the main body portion 231) is a free end. Here, the slit 233 extends to the base end in the central axis direction of the main body 231. In addition, a pair of slits 233 adjacent to each other with the pressing portion 234 interposed therebetween communicate with each other in the circumferential direction at a proximal end portion in the central axis direction of the main body portion 231. As a result, the elastic deformation portion 236 of the pressing portion 234 is supported by the distal end side portion (base end portion of the elastic deformation portion 236) in the central axis direction of the main body portion 231, and the proximal end portion (elasticity) of the main body portion 231. The tip of the deformable portion 236 is a free end. Further, the protruding portion 35 is formed in a portion of the elastically deforming portion 236 on the proximal side from the middle in the extending direction. That is, the pressing portion 234 has the distal end portion of the elastic deformation portion 236 that is a free end and the projection portion 35 is formed at the proximal end side portion of the elastic deformation portion 236, so that the distal end portion is inside and outside the main body portion 231. It is easy to bend greatly depending on the direction.

  When the terminal member 230 is fitted into the end portion of the winding shaft 20, the elastic deformation portion 236 is elastically deformed to the inner peripheral side by the protrusion 35 abutting on the inner peripheral portion of the winding shaft 20. . More specifically, since the front end portion of the elastic deformation portion 236 is a free end, the pressing portion 234 projects toward the inner peripheral side as the front end portion. When the rotation support portion 45a is inserted into the terminal member 230, a portion of the elastic deformation portion 236 on the distal end side from the projection portion 35 is mainly pushed back to the outer peripheral side. In this state, the pressing portion 234 presses the rotation support portion 45a to the inner peripheral side by a force that the elastic deformation portion 236 tries to elastically return to the shape projecting to the inner peripheral side of the main body portion 231. More specifically, the elastic deformation portion 236 is not only a portion near the center in the extending direction but also a portion on the tip side from the projection portion 35 as a whole by the force to elastically return to the inner peripheral side. It extends in contact with the cylindrical outer peripheral surface of 45a.

  According to the terminal member 230 according to the first modified example, the tip side portion of the pressing portion 234 can be more easily bent, and the contact area with the rotation support portion 45a can be increased. Thereby, the rattling between the terminal member 230 and the rotation support part 45a can be more effectively suppressed, and the winding shaft 20 can be rotated more smoothly.

  Although FIG. 21 shows an example of a non-penetrating terminal member 230, the terminal member may be formed in a penetrating type.

<Second Modification>
Next, the terminal member 330 which concerns on a 2nd modification is demonstrated (refer FIGS. 25-28). Here, the penetrating terminal member 330 will be described as an example. The terminal member 330 according to the second modification has a pressing portion 334 that protrudes from the cylindrical inner peripheral surface of the main body portion 331 toward the inner peripheral side. In addition, about the structure similar to the terminal member 30, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The pressing portion 334 of the terminal member 330 is formed in a shape that protrudes from the cylindrical inner peripheral surface of the main body portion 331 toward the inner peripheral side in the original form. And the press part 334 is contact | abutted to the cylindrical outer peripheral surface of the rotation support part 45a in the state in which the rotation support part 45a was inserted, and is elastically deformed to the outer peripheral side.

  The pressing portion 334 includes an elastic deformation portion 336 that can be elastically deformed in the inner and outer directions of the main body portion 331, and a projection portion 335 that protrudes from the elastic deformation portion 336 toward the inner peripheral side of the main body portion 331. More specifically, the pressing portion 334 has the protrusion 335 from the inner peripheral surface of the main body portion 331 toward the inner peripheral side from the inner surface of the elastic deformation portion 336 extending along the inner peripheral surface of the main body portion 331. It protrudes. Further, the elastic deformation portion 336 is formed so that the outer peripheral side end portion is located on the inner peripheral side from the outer peripheral portion of the main body portion 331. That is, the elastic deformation portion 336 can be elastically deformed to the outer peripheral side even when the terminal member 330 is fitted into the winding shaft 20 (see FIGS. 27 and 28).

  Further, in the central axis direction of the main body portion 331, a slit 333 extending along the circumferential direction is formed in at least one side portion (here, both side portions) of the pressing portion 334. Here, the elastic deformation portion 336 extends along the circumferential direction and is formed in a cantilever shape. More specifically, the slit 333 communicates in the central axis direction of the main body portion 331 at one end portion in the circumferential direction of the main body portion 331. That is, the elastic deformation portion 336 is supported at one end (the distal end portion of the elastic deformation portion 336) in the circumferential direction of the main body portion 331 as a free end and supported at the other end (the base end portion of the elastic deformation portion 336). Further, the protruding portion 335 is formed in a portion of the elastically deforming portion 336 on the tip side from the intermediate portion in the extending direction. Preferably, the protrusion 335 is formed at the tip of the elastic deformation portion 336 that is more easily elastically deformed. Here, the protrusion 335 is formed in a hemispherical convex shape.

  And if the rotation support part 45a is inserted inside in the state in which the terminal member 330 was inserted in the edge part of the winding shaft 20, the projection part 335 will contact | abut to the cylindrical outer peripheral surface of the rotation support part 45a, and the outer peripheral side The elastic deformation portion 336 is elastically deformed to the outer peripheral side by being pushed by (see FIG. 28). As a result, the projection 335 is pressed against the cylindrical outer peripheral surface of the rotation support portion 45a by the force with which the elastic deformation portion 336 attempts to return to its original shape. That is, the pressing part 334 presses the rotation support part 45a to the inner peripheral side.

  According to the terminal member 330 according to the second modification, the pressing portion 334 itself protrudes from the cylindrical inner peripheral surface of the main body portion 331 to the inner peripheral side in the original form, and thus the rotation support portion 45a is disposed on the inner peripheral side. The backlash between the terminal member 330 and the rotation support portion 45a can be suppressed by pressing the pin.

  Although the penetration type terminal member 330 has been described here, the main body portion 331a may be formed in a non-penetration type like a terminal member 330a shown in FIG.

  Moreover, even if the terminal member 330b as shown in FIGS. 30-33 is employ | adopted as an example in which the press part is formed in the shape which protrudes in the inner peripheral side from the cylindrical internal peripheral surface of a main body part with the original form. Good. The terminal member 330b has a pressing portion 334b that projects from the cylindrical inner peripheral surface of the main body portion 331b toward the inner peripheral side. The pressing part 334b extends in the circumferential direction of the main body part 331b. A slit 333 is formed along at least one side (here, both sides) of the pressing portion 334b in the central axis direction of the main body portion 331b along the circumferential direction of the main body portion 331b.

  The pressing portion 334b is formed to be elastically deformable in the inner and outer directions of the main body portion 331b. More specifically, the pressing portion 334b is formed in a shape that protrudes from the inner peripheral surface of the main body portion 331b to the inner peripheral side. Further, the pressing portion 334b is formed such that the outer peripheral side end portion is located on the inner peripheral side with respect to the outer peripheral portion of the main body portion 331b. That is, the pressing portion 334b can be elastically deformed to the outer peripheral side even when the terminal member 330b is fitted into the winding shaft 20 (see FIG. 32).

  When the rotation support portion 45a is inserted inside with the end member 330b fitted into the end portion of the winding shaft 20, the pressing portion 334b contacts the outer peripheral surface of the rotation support portion 45a and pushes the outer periphery side. It is moved and elastically deformed to the outer peripheral side (see FIG. 33). Thereby, the pressing part 334b presses the rotation support part 45a to the inner peripheral side by a force to elastically return to the original shape.

  According to the terminal member 330b according to this configuration, since the elastically deformable pressing portion 334b extending in the circumferential direction is in sliding contact with the columnar outer peripheral surface of the rotation support portion 45a, the end member 330b is interposed between the terminal member 330b and the rotation support portion 45a. The rotation operation of the winding shaft 20 can be made smoother while suppressing rattling.

  Here, although the penetration type terminal member 330b has been described, the main body portion 331c may be formed in a non-penetration type like a terminal member 330c shown in FIG.

  Moreover, even if the terminal member 330d as shown in FIGS. 35-37 is employ | adopted as an example in which the press part is formed in the shape which protrudes to the inner peripheral side from the cylindrical inner peripheral surface of a main-body part by the original form. Good. The terminal member 330d has a pressing portion 334d that projects from the cylindrical inner peripheral surface of the main body portion 331d toward the inner peripheral side. The pressing portion 334d extends in the central axis direction of the main body portion 331d. A slit 333d along the central axis direction of the main body portion 331d is formed in at least one side portion (here, both side portions) of the pressing portion 334d in the circumferential direction of the main body portion 331d.

  More specifically, the pressing portion 334d is formed in a cantilever shape and can be elastically deformed in the inner and outer directions of the main body portion 331d. That is, the slit 333d is formed from the base end portion to the distal end portion of the main body portion 331d, and is also opened on the distal end side. In other words, the pressing portion 334d is supported by the proximal end portion in the central axis direction of the main body portion 331d, and the distal end portion is a free end. Further, the pressing portion 334d is formed in a shape protruding from the cylindrical inner peripheral surface of the main body portion 331d to the inner peripheral side. Here, the pressing portion 334d is formed so as to protrude toward the inner peripheral side of the main body portion 331d toward the distal end portion which is a free end. Further, the pressing portion 334d is formed such that the outer peripheral side end portion is located on the inner peripheral side from the outer peripheral portion of the main body portion 331d. That is, the pressing portion 334d can be elastically deformed to the outer peripheral side even when the terminal member 330d is fitted into the winding shaft 20 (see FIG. 37).

  Then, when the rotation support portion 45a is inserted inside with the end member 330d fitted into the end portion of the winding shaft 20, the pressing portion 334d comes into contact with the columnar outer peripheral surface of the rotation support portion 45a and the outer peripheral side To be elastically deformed to the outer peripheral side. Thereby, the pressing part 334d presses the rotation support part 45a to the inner peripheral side by a force for elastically returning to the original shape.

  According to the terminal member 330d according to this configuration, the pressing portion 334d is supported by the proximal end portion in the central axis direction of the main body portion 331d and is a free end at the distal end portion. And productivity can be improved.

  Here, although the penetration type terminal member 330d has been described, the main body 331e may be formed in a non-penetration type like a terminal member 330e shown in FIG.

More specifically, the pressing portion 446 includes an elastic deformation portion 448 that can be elastically deformed in the inner and outer directions of the rotation support portion 445a, and a protrusion portion 447 that protrudes from the outer peripheral portion of the elastic deformation portion 448 to the outer peripheral side. (See FIG. 39).

  The elastic deformation portion 448 extends along the central axis direction of the rotation support portion 445a. More specifically, the elastic deformation portion 448 occupies a part in the circumferential direction of the cylindrical portion of the rotation support portion 445. Further, the protruding portion 447 protrudes from the central portion in the extending direction of the elastically deforming portion 448 that is more easily elastically deformed to the outer peripheral side. Here, the protrusion 447 is formed in a hemispherical convex shape. A plurality (three in this case) of the pressing portions 446 are provided at equal intervals in the circumferential direction of the rotation support portion 445a.

  Then, when the rotation support portion 445 a is inserted inside with the end member 430 fitted into the end of the winding shaft 20, the protrusion 448 of the pressing portion 446 contacts the cylindrical inner peripheral surface of the end member 430. Touch. Then, the protrusion 448 is pushed to the inner peripheral side, and the elastic deformation portion 447 is elastically deformed to the inner peripheral side. Thereby, the pressing part 446 presses the terminal member 430 to the outer peripheral side by the force that the elastic deformation part 447 attempts to return elastically.

<Fourth embodiment>
Next, the sheet winding device 610 according to the fourth embodiment will be described (see FIG. 45). A part of the sheet winding device 610 that is different from the sheet winding device 510 according to the third embodiment is that a pressing portion 646 is formed on the rotation support portion 645a. The description is omitted.

  The terminal member 630 includes a main body portion 531, a shaft portion 637, and an overhang portion 538. The shaft portion 637 is formed in a cylindrical shape and has a cylindrical outer peripheral surface, and is connected to the base end portion of the main body portion 531 in the center axis direction so that the center axis coincides.

  The rotation support portion 645a is formed to be capable of supporting the shaft portion 637 of the terminal member 630 so as to be relatively rotatable around the central axis. More specifically, the rotation support portion 645a is formed in a bearing shape having a cylindrical inner peripheral surface. The rotation support portion 645a is set to be larger than the diameter of the shaft portion 637 (here, slightly larger).

  The rotation support portion 645a is provided with a pressing portion 646 that presses the cylindrical outer peripheral surface of the shaft portion 637 toward the inner peripheral side (see FIG. 44). The pressing part 646 is formed in a shape protruding from the cylindrical inner peripheral surface to the inner peripheral side. The pressing portion 646 abuts on the cylindrical outer peripheral surface of the shaft portion 637 of the terminal member 630 and is elastically deformed outward. The pressing portion 646 extends along the central axis direction of the rotation support portion 645a. In addition, a slit 649 is formed along at least one side (here, both sides) of the pressing portion 646 in the circumferential direction of the rotation support portion 645a along the central axis direction of the rotation support portion 645a. More specifically, the slit 649 is formed from the middle part of the cylindrical inner peripheral surface to the tip part in the central axis direction of the rotation support part 645a, and is opened at the tip part. The pressing portion 646 has an elastic deformation portion 648 and a projection portion 647.

  When the shaft portion 637 of the terminal member 630 is inserted into the rotation support portion 645a of the side cover 644a, the protruding portion 647 contacts the columnar outer peripheral surface of the shaft portion 637. In this state, the elastic deformation portion 648 elastically deforms to the outer peripheral side of the rotation support portion 645a, and presses the shaft portion 637 to the inner peripheral side by a force for elastic return to the original shape.

  According to the sheet take-up device 610 according to the fourth embodiment, the pressing portion 646 that presses the shaft portion 637 to the inner peripheral side is provided on the rotation support portion 645a. Shaking can be suppressed.

  As mentioned above, although this invention was demonstrated in detail, above-described description is an illustration in all the phases, Comprising: This invention is not limited to it.
