Japanese Patent No. 3314300 Japanese Patent No. 4456133

  In the winding device described in Patent Document 1, since a minute gap is generated between the notch of the holding portion and the slide lock member, it is inevitable that rattling and the accompanying noise occur. On the other hand, in the winding device described in Patent Document 2, since the engaging element is brought into close contact with the notch of the holding portion by the urging force of the urging protrusion, the occurrence of rattling is suppressed. However, since the biasing protrusion on the bottom surface of the holding portion is exposed when the winding device is removed from the holding portion, improvement is desired from the viewpoint of design. Further, when the pair of engaging elements are engaged with the notches, if the winding device is tilted with respect to the horizontal direction and attached to the attachment portion, only one of the engaging elements may be engaged. In such a state, the winding device is not firmly held, and the effect of suppressing rattling cannot be obtained. Furthermore, depending on the option setting and grade of the vehicle, the tonneau cover device may not be provided even for the same type of vehicle. When the urging mechanism is provided on the bottom surface of the holding portion of the vehicle regardless of the presence or absence of the tonneau cover device for the common use of the vehicle structure, the cost of the urging mechanism is wasted in a vehicle without the tonneau cover device.

  The present invention is less susceptible to rattling when being held by the holding part, is easy to mount, improves the design of the holding part when removed from the holding part, and does not cause unnecessary costs An object is to provide a winding device.

  The winding device of the present invention includes a first side surface provided with a first notch, a second side surface facing the first side surface and provided with a second notch, and a bottom surface. Is held by a holding portion having a concave portion. The winding device includes a winding shaft around which a sheet-like cover is wound so as to be wound and withdrawn, and a first holder provided at one end of the winding shaft. The first holder is engaged with the first notch member that is movable between an engaging position that engages with the first notch and a separated position that is separated from the first notch, and the second notch. By combining, the first claw member that holds the first holder together with the first claw member in the engagement position, and the first claw member that urges the first claw member toward the engagement position The biasing member, a switch member connected to the first claw member and moving the first claw member toward the separated position, and abutting the bottom surface when the first holder is held by the holding portion, A second urging member that presses the first and second claw members against the first and second notches, respectively.

  According to the present invention, when the first holder is held by the holding portion, the first and second claw members are pressed against the first and second notches by the second urging member, respectively. It is difficult for rattling to occur. Further, since the second urging member is incorporated in the winding device, a mechanism for urging the first and second claw members is not required on the bottom surface of the concave portion of the holding portion. Appearance is simple. For this reason, the cost of the urging mechanism is not wasted in the grade in which the tonneau cover device is not set. Furthermore, according to the present invention, the winding device is rotated, and the second claw member and the first claw member are engaged with the cutouts in this order, so that it is not necessary to hold the winding device horizontally. Therefore, according to the present invention, rattling is unlikely to occur when being held by the holding portion, the mounting operation is easy, the design of the holding portion is improved when removed from the holding portion, and wasted It is possible to provide a winding device that does not generate costs.

(First embodiment)
FIG. 1 is a perspective view of a tonneau cover device 2 to which the present invention is applied, and FIG. 2 is a perspective view of a winding device 3 according to the first embodiment. The tonneau cover device 2 includes a winding device 3 and a sheet-like tonneau cover 4. The winding device 3 includes a winding shaft 5 around which the tonneau cover 4 can be wound and pulled out, and first and second holders 6, 7 provided at one end and the other end of the winding shaft 5, respectively. And a casing 8 that covers the winding shaft 5. The first and second holders 6 and 7 support the winding shaft 5 in a rotatable manner. The casing 8 is a cylindrical member that is formed of aluminum, resin, or the like and extends in the left-right direction (Y direction) of the automobile. The casing 8 has a size that can accommodate the tonneau cover 4 completely wound around the winding shaft 5. The tonneau cover 4 is formed of synthetic resin, cloth, or the like, and a thick and highly rigid gripping edge 4a is provided at the tip of the tonneau cover 4 so that the tonneau cover 4 can be easily gripped when the tonneau cover 4 is pulled out. The casing 8 has a slit 8a extending in the Y direction so that the winding shaft 5 can be wound and pulled out. The slit 8a has a size through which the tonneau cover 4 can pass. On the other hand, the thick gripping edge 4a has a thickness larger than the height of the slit 8a and cannot pass through the slit 8a. The first holder incorporates a biasing means (not shown) for biasing the winding shaft 5 in the winding direction.

  The garnish trim 9 is provided with a holding portion 10 that holds the winding device 3. Further, a guide rail 11 (see FIG. 3) for guiding the tonneau cover 4 in the X direction while sliding the end of the gripping edge 4a of the tonneau cover 4 from the rear side of the holding unit 10 toward the rear end of the vehicle is provided. It may be done.

  In the vicinity of the rear end of the vehicle, a locking portion (not shown) that can engage the left and right ends of the gripping edge 4a is provided.

  FIG. 3 is a perspective view of the holding unit 10. The holding unit 10 is formed integrally with the garnish trim 9, but may be formed as a member independent of the garnish trim 9 and attached to the garnish trim 9. Although not shown, the left and right holding portions 10 have the same configuration except that they have a mirror-symmetric shape with respect to the XZ plane (a plane parallel to the X direction and the Z direction). The holding part 10 has a concave part 11 which is open at the top and receives the first and second holders 6 and 7 from above. Referring also to FIG. 5, the recess 11 includes first and second side surfaces 13 and 14 and a bottom surface 12 that face each other. A first notch 15 is provided on the first side surface 13, and a second notch 16 is provided on the second side surface 14. The first notch 15 and the second notch 16 are formed so as to penetrate the holding part 10 in the Y direction, but may be formed only in a part of the holding part 10 in the Y direction. The first notch 15 and the second notch 16 are formed at the same height. In the present embodiment, the first notch 15 and the second notch 16 have the same shape. For this reason, the two holding portions 10 have the same shape, but the first notch 15 and the second notch 16 may have different shapes. A cover member that covers the first and second cutouts 16 when the winding device 3 is removed may be separately provided.

  When pulling out the tonneau cover 4, the user grasps the gripping edge 4a of the tonneau cover 4 and pulls it back in the X direction, and engages the locking means with the left and right ends of the gripping edge 4a. Thereby, the upper part of the tonneau part is covered with the tonneau cover 4. When retracting the tonneau cover 4, the user removes the gripping edge 4a from the locking means. The tonneau cover 4 is wound up by the winding device 3, the gripping edge 4a moves forward in the X direction, and only the gripping edge 4a is left outside the winding device 3. In this way, the upper part of the tonneau part can be opened.

  Next, the configuration of the first and second holders 6 and 7 will be described. Only one of the first holder 6 and the second holder 7 includes a biasing means that biases the winding shaft 5 in the winding direction, and supports the biasing means and the winding shaft 5. The shape is mirror-symmetric with respect to the XZ plane except that the shapes to be different are different. Accordingly, the first holder 6 will be described below. 4 is an exploded perspective view of the first holder 6. FIG. 5A is a cross-sectional view taken along line AA in FIG. 4, and FIG. 5B is taken along line BB in FIG. It is sectional drawing.

  The first holder 6 has a housing 61 fixed to the casing 8. The housing 61 is formed of polyacetal, but the material is not limited, and a material such as resin or metal can be used as appropriate. A surface (surface on the near side in FIG. 4) facing the casing 8 of the housing 61 is an opening, and a shaft support portion 62 having a hole 62a that rotatably supports the winding shaft 5 is formed at the center. Yes. The hole 62a has a star-shaped cross section and can accommodate the biasing means. The cross-sectional shape of the housing 61 is generally rectangular, but the corners are rounded to facilitate gripping.

  Inside the housing 61, a guide portion 63 having a cavity 63a extending in the X direction is provided, and a first claw member 64 and a first biasing member 66 in the form of a coil spring are accommodated in the cavity 63a. ing. The cavity 63 a communicates with a hole 62 a that supports the winding shaft 5. An end portion of the guide portion 63 on the housing 61 side is an opening 63b through which the first claw member 64 can advance and retract. A wall surface 63c is provided on the opposite side of the guide portion 63, and one end of the first urging member 66 is fixed to the wall surface 63c. A ring-shaped groove 64 b that accommodates the other end of the first urging member 66 is formed on the surface of the first claw member 64 that faces the first urging member 66. A claw portion 64a having a tapered shape whose dimension in the Z direction decreases toward the tip is formed at the opposite end portion of the first claw member 64. The first urging member 66 is compressed and urges the first claw member 64 in a direction to push it out of the opening 63b. The claw portion 64 a enters the inside of the first notch 15 of the holding portion 10 by the urging force of the first urging member 66, and the upper surface of the claw portion 64 a abuts on the lower surface of the first notch 15. The first notch 15 is engaged. The first claw member 64 is formed of the same material as that of the housing 61, but may be formed of a material different from that of the housing 61.

  The first holder 6 has a switch member 68. The switch member 68 has an operation part 68 a located outside the housing 61 and an arm part 68 b located inside the housing 61. An opening 61a through which the switch member 68 passes is formed in the vicinity of the connection portion between the operation portion 68a and the arm portion 68b of the housing 61. An end portion 68c of the arm portion 68b opposite to the connection portion with the operation portion 68a is connected to the first claw member 64. The operation portion 68a and the arm portion 68b are created as separate members. After the arm portion 68b is connected to the first claw member 64, the engagement portions formed on the operation portion 68a and the arm portion 68b are engaged with each other. Integrated. The operation portion 68a is directed in the X direction along the outer surface of the housing 61, more specifically, in a direction in which the first claw member 64 is pulled into the guide portion 63 against the urging force of the first urging member 66. Can slide. The switch member 68 is formed of the same material as that of the housing 61, but may be formed of a material different from that of the housing 61 in order to stand out, or may be colored in a color different from that of the housing 61. In order to improve the operability of the operation unit 68a, the surface 68d to be pressed by the finger of the operation unit 68a has a shape recessed inward.

  A second claw member 65 is fixed to the opposite side of the opening 63b of the housing 61 where the first claw member 64 advances and retreats. The second claw member 65 is provided at substantially the same Z-direction height as the first claw member 64, but may be located at a position different from the first claw member 64. The second claw member 65 has substantially the same shape as the claw portion 64 a of the first claw member 64, but may have a shape different from that of the claw portion 64 a of the first claw member 64. The second claw member 65 is integrally formed with the housing 61, but may be formed as a separate member and joined to the housing 61. The second claw member 65 is engaged with the second notch 16 in the same manner as the first claw member 64, that is, when the upper surface of the second claw member 65 abuts the lower surface of the second notch 16. Match. As a result, the second claw member 65 can hold the first holder 6 in the holding portion 10 together with the first claw member 64 in the engaged position.

  As described above, the housing 61 supports the first claw member 64 so as to be movable between the engagement position where the first claw member 64 is engaged with the first notch 15 and the separated position which is separated from the first notch 15. The second claw member 65 is fixedly supported. The first claw member 64 is urged toward the engagement position by the first urging member 66 and is moved toward the separated position by the switch member 68. Thus, the first claw member 64 can move between the engagement position and the separation position.

  The first holder 6 has a second urging member 67. The second urging member 67 has a spring member 67a supported by the housing 61 and a pressing member 67b connected to the spring member 67a. The pressing member 67 b is pressed against the bottom surface 12 of the recess 11 by the spring member 67 a when the first holder 6 is held by the holding unit 10. The second urging member 67 contacts the bottom surface 12 when the first holder 6 is held by the holding portion 10, and the first and second claw members 64 and 65 are respectively cut away from the first and second notches. Press against 15 and 16. The housing 61 has an opening 61 b at a position facing the bottom surface 12 of the recess 11. The pressing member 67b is a lever member 67b that rotates so as to protrude from the opening 61b. One end of the lever member 67 b is rotatably supported by the housing 61, and the other end forms a pressing portion 67 c that is pressed against the bottom surface 12 of the recess 11 outside the housing 61. The spring member 67 a is a compression spring provided between the lever member 67 b and the housing 61. A lower part of the spring member 67a is formed on the upper surface of the lever member 67b and is held by a rod-like first spring holding part 67d extending in the Z direction, and an upper end of the spring member 67a is a plate-like second protruding from the guide part 63 in the Y direction. Is held by the spring holding portion 69. The configuration and position of the second spring holding portion 69 are not limited to this. The upper end of the spring member 67a may be fixed to the housing 61 or a member integrated with the housing 61. The pressing member 67 b is formed of the same material as that of the housing 61, but may be formed of a material different from that of the housing 61.

  Next, a procedure for attaching the first holder 6 to the concave portion 11 of the holding unit 10 will be described with reference to FIGS. 6 to 9, (a) shows a cross-sectional view along the line AA in FIG. 4 as in FIG. 5 (a), and (b) in FIG. 4 as in FIG. 5 (b). Sectional drawing along the BB line is shown. Since the second holder 7 has the same basic configuration as the first holder 6, it can be attached and detached by the same operation as the first holder 6.

  First, as shown in FIG. 6, the first holder 6 is brought close to the recess 11 while pressing the lever member 67 b against the first edge 11 a of the recess 11 of the holding unit 10. The first claw member 64 protrudes from the housing 61, and the switch member 68 is at a position rearward in the X direction. Next, as shown in FIG. 7, while the lever member 67 b is pressed against the first edge portion 11 a of the recess 11, the first holder 6 is rotated counterclockwise and moved toward the inside of the recess 11. The first claw member 64 protrudes from the housing 61, and the switch member 68 is at a position rearward in the X direction. Next, as shown in FIG. 8, the first holder 6 is lowered toward the inside of the recess 11. Since the lever member 67b is separated from the first edge portion 11a of the recess 11, the lever member 67b protrudes from the housing 61 by the biasing force of the spring member 67a. The switch member 68 is at a position rearward in the X direction. The second claw member 65 is on the side of the second notch 16 of the recess 11.

  Next, as shown in FIG. 9, the first holder 6 is rotated clockwise while being lowered toward the inside of the recess 11. At this time, by bringing the upper surface of the second claw member 65 into contact with the lower surface of the second notch 16, the first holder 6 can be stably rotated with the contact portion as the rotation center. In addition, the second claw member 65 is thereby engaged with the second notch 16. The first claw member 64 contacts the upper side wall 11 c of the recess 11 and moves toward the inside of the housing 61 against the urging force of the first urging member 66. As a result, the first holder 6 continues to descend while the first claw member 64 is in contact with the upper side wall 11 c of the recess 11. Since the claw portion 64a of the first claw member 64 protrudes on the upper side and has a slope 64c that the lower side is drawn toward the lower surface, the slope 64c of the claw portion 64a slides along the first edge portion 11a of the recess 11. The first claw portion 64a can be pulled in smoothly. The lever member 67b remains protruding from the housing 61. When the first holder 6 is further rotated clockwise while being lowered, the lever member 67b comes into contact with the bottom surface 12 of the recess 11 and is pushed into the housing 61 against the urging force of the spring member 67a as shown in FIG. It is. Further, the first claw member 64 enters the inside of the first notch 15 from the upper side wall 11 c of the recess 11 and engages with the first notch 15.

  When removing the first holder 6, the switch member 68 is pushed forward in the X direction without pressing the first holder 6 downward. Since the first claw member 64 moves toward the separated position toward the inside of the housing 61, the first holder 6 is not obstructed by the first claw member 64 and is moved upward by the biasing force of the spring member 67 a. Jump up. By appropriately selecting the spring force of the spring member 67a, the first claw member 64 passes through the upper side wall 11c while maintaining the separated position at the moment when the switch member 68 is pushed, and the state shown in FIG. 8 is obtained. In the state of FIG. 8, the first holder 6 is lifted while rotating counterclockwise, and when the first holder 6 is almost detached from the recess 11 as shown in FIG. 7, the first holder 6 is then rotated clockwise, Return to the state shown in FIG.

  Thus, according to this embodiment, the first holder 6 is rotated counterclockwise along the first edge portion 11a of the recess 11 so as to push the lever member 67b, and then is rotated clockwise while being lowered. The first holder 6 can be attached by a simple operation. Further, the first holder 6 can be removed by a simple operation of pushing the switch member 68, rotating the first holder 6 jumped up counterclockwise, taking it out from the recess 11, and finally rotating it clockwise. Since these movements can be realized only by wrist rotation and finger movement, the posture of the user is irrelevant. Conventionally, the user had to put the upper body into the back of the luggage space (front side), and then moved the holder up and down in that state, so the burden on the upper body and arms was heavy. In particular, a car with a large luggage space or a small user may be forced to take a rather unreasonable posture. However, in this embodiment, such a burden on the user is reduced, and the first holder 6 can be attached and detached more easily. Further, since the winding device 3 is attached while being rotated, it is not necessary to keep the winding device 3 horizontal when the first holder 6 is attached to the holding unit 10. For this reason, attachment operation of the winding device 3 becomes easier. Since the winding device 3 is attached while being rotated, rattling can be more reliably suppressed as compared with the winding device of Patent Document 2.

  Depending on the shape of the first holder 6 and the concave portion 11, it is not necessary to press the lever member 67 b against the first edge portion 11 a of the concave portion 11 of the holding portion 10 when attaching the first holder 6. In other words, even when the lever member 67b protrudes from the housing 61, the second claw member 65 does not interfere with the first edge 11a of the recess 11 and the second edge 11b of the recess 11 (FIG. 8 ( If it does not interfere with a) see), the first holder 6 can be inserted into the recess 11 in a floating state. On the other hand, when the first holder 6 is attached, the first claw portion 64a naturally comes into contact with the upper side wall 11c of the recess 11 and retreats into the housing 61. However, the first claw portion 64a is intentionally pushed by pressing the switch member 68. The claw portion 64 a may be retracted into the housing 61. Similarly, when removing the first holder 6, the switch member 68 may be continuously pressed until the first claw portion 64 a is released from the recess 11.

  This embodiment further has the following advantages. First, when the first holder 6 is held by the holding portion 10, the first and second claw members 64 and 65 that engage with the first and second notches 15 and 16, respectively, It is urged upward by the urging member 67. For this reason, the upper surfaces of the first and second claw members 64 and 65 are in close contact with the lower surfaces of the first and second notches 15 and 16, and the first and second claws that may occur due to manufacturing errors or the like. Shaking between the members 64 and 65 and the first and second notches 15 and 16 is suppressed. Next, an urging protrusion (see Patent Document 2) conventionally provided on the bottom of the recess 11 is unnecessary. For this reason, the recess 11 has no irregularities other than the first and second cutouts 15 and 16 formed in the first and second side surfaces 13 and 14, respectively, and the design is improved. In this embodiment, the shape of the recess 11 is substantially rectangular in a side view, but the connecting portion between the bottom surface 12 and the first and second side surfaces 13 and 14 is formed with a smooth curved surface, or the bottom surface 12 is formed with a curved surface. It is also possible to do. Furthermore, since the second claw member 65 is fixed, the structure of the first holder 6 is simplified.

  The configuration of the first claw member 64 is not limited to the above. FIG. 10 shows a conceptual diagram of the first claw member 164 having another configuration. In this modified example, the first claw member 164 has a plate-like first portion 164 a and a plate-like second portion 164 b urged by the first urging member 66. The first portion 164a is rotatably supported by the housing 61 by a first support portion 164d located at one end thereof, and a claw portion 164c is formed at the other end. The first portion 164a is a second support portion 165e located in the middle thereof, and is rotatably connected to the second portion 164b. Therefore, the first portion 164a and the second portion 164b form a link mechanism as a whole. As shown in FIG. 10A, the first portion 164a is pushed outward through the second portion 164b by the urging force of the first urging member 66, and the timepiece is centered on the first support portion 164d. It rotates around and engages with the first notch 15 (not shown, but finally the claw portion 164c is engaged with the first notch 15 by the reaction force of the spring member 67a). When the switch member 68 moves to the left, as shown in FIG. 10B, the first portion 164 a rotates counterclockwise around the first support portion 164 d and separates from the first notch 15. In this case, it is necessary to operate the switch member 68 while pushing the first holder 6 in order to separate the claw portion 164c from the first notch 15. That is, as long as the first claw member 64 is urged toward the engagement position by the first urging member 66 and is moved toward the separated position by the switch member 68, any configuration is adopted. Can do.

  The second urging member 67 is not limited to the one described above. FIG. 11 shows a conceptual diagram of the second urging members 167, 267, 367, 467 having other configurations. Referring to FIG. 11A, a bottom plate member 167a corresponding to the above-described lever member 67b is rotatably supported by the housing 61. A spring 167 b is wound around the shaft support portion 62 of the housing 61. Both ends of the spring 167b are fixed to the upper surface of the bottom plate member 167a, and the spring 167b biases the bottom plate member 167a downward in the Z direction. The bottom plate member 167a is normally located at a solid line, but when pressed against the bottom surface 12 of the recess 11, the bottom plate member 167a rotates counterclockwise as indicated by a two-dot chain line.

  Further, as shown in FIG. 12, the holding portion 10 preferably has a guide surface 11 d inclined downward toward the concave portion 11 above the first notch 15. FIG. 12A is a side view of the first holder 6 and the holding unit 10, and FIG. 12B is a perspective view of the holding unit 10. As described above, the first holder 6 is held by the holding unit 10 by being moved downward while changing the rotation direction. Accordingly, the first holder 6 can be moved more smoothly by inclining the holding portion 10 so as to guide the downward movement of the first holder 6. It is also preferable to provide a guide rib 11f extending at substantially the same angle as the downward slope of the guide surface 11d on the back wall 11e of the holding portion 10. Although illustration is omitted, a rib or a groove that engages with the guide rib 11f is provided at a position facing the guide rib 11f of the first holder 6, and the first holder 6 can be moved along the guide rib 11f. Alternatively, the first holder 6 can be moved along the guide rib 11f so that the upper end portion of the first holder 6 is engaged with the guide rib 11f. As a result, the insertion angle of the first holder 6 is stabilized, and the first holder 6 can be smoothly guided to the recess 11.

  It is also preferable that the second side surface 14 of the holding portion 10 is made higher than the second claw member 65 when the first holder 6 is placed on the downwardly inclined guide surface 11d. As a result, the second claw member 65 is less likely to be caught on the upper surface 14a of the second side surface 14, and the first holder 6 can be guided to the recess 11 more smoothly.

  In the present embodiment, the first claw member 64 is provided on the rear side of the vehicle and the second claw member 65 is provided on the front side of the vehicle. In this case, the rotation direction at the time of attaching and removing the first holder 6 is opposite to that of the above-described embodiment. That is, when the first holder 6 is attached, the first holder 6 is first rotated clockwise and then counterclockwise as viewed from the left side of the vehicle. Although not shown, the second claw member 65 may be movable like the first claw member 64. In the embodiment described above, it is necessary to first insert the fixed second claw member 65 into the recess 11 when the first holder 6 is attached. However, by configuring the second claw member 65 so as to be able to advance and retreat, either claw member can be inserted first. In other words, the first holder 6 can be rotated in either direction according to the situation of the user's dominant hand or a usable hand, thereby improving convenience.

  FIG. 13 shows still another modification of the present embodiment. In the above-described embodiment, when the switch member 68 is pushed and the first claw member 64 is retracted into the housing 61 and the finger is released from the switch member 68, the first biasing member 66 biases the first member. The claw member 64 is pushed out of the housing 61. On the other hand, in this modification, a pin portion 64d that can be elastically deformed is provided on the lower surface of the first claw member 64, and a claw portion 64e that bulges downward is formed at the tip of the pin portion 64d. Further, a stepped portion 61 c is provided on the inner surface of the housing 61. As shown in FIG. 13A, when the switch member 68 is pushed leftward with the first claw member 64 protruding from the housing 61, the lower surface of the pin portion 64d is brought into contact with the step portion 61c while contacting the step portion 61c. Move relative to it. Then, as shown in FIG. 13B, the claw portion 64e rides on the upper surface of the step portion 61c, whereby the pin portion 64d is elastically deformed upward. When the first claw member 64 is further moved to the left side, as shown in FIG. 13C, the lower end of the claw portion 64e is separated from the stepped portion 61c, and the pin portion 64d is elastically deformed and returns to its original shape. The claw portion 64e abuts on the stepped portion 61c by the urging force of the first urging member 66, but the first claw member 64 cannot be displaced to the right side beyond the stepped portion 61c. Even if the button is released, it is maintained in a state of being retracted into the housing 61.

  Further, in the present modification, a protrusion 67 e is formed on the second urging member 67. The protruding portion 67e is provided on the base side of the pin portion 64d with respect to the stepped portion 61c, and faces the pin portion 64d. When the second urging member 67 comes into contact with the bottom surface 12 of the recess 11, the protrusion 67e rises and pushes up the pin 64d. When the lower end of the claw portion 64e is raised above the upper end of the stepped portion 61c, the restraining force of the stepped portion 61c is released, and the first claw member 64 is moved by the urging force of the first urging member 66. Pushed out. According to this modification, the first claw member 64 is maintained in the retracted state inside the housing 61 simply by pressing the switch member 68, and the first holder 6 is pressed against the bottom surface 12 of the concave portion 11. Since the state is automatically released, it becomes easier to attach the first holder 6 to the recess 11. Even when the first holder 6 is removed, the first claw member 64 is locked in the retracted state inside the housing 61 by pushing the switch member 68 first, so that the removal becomes easy. The first claw member 64 is not limited to the configuration including the pin portion 64d, the stepped portion 61c, and the protruding portion 67e as long as it maintains the retracted state and can release the state. Configuration can be taken.

(Second Embodiment)
FIG. 14A is a perspective view of the winding device 103 according to the second embodiment, and FIG. 14B is a partial detailed view of the vicinity of the second holder 107. The first holder 6 has the same configuration as that of the first embodiment. In the present embodiment, the second holder 107 is provided so as to be movable with respect to the winding shaft 5 in a direction parallel to the long axis of the winding shaft 5. A spring 117 is provided between the second holder 107 and the winding shaft 5, and the winding device 103 is contracted in the Y direction by pressing the second holder 107 toward the first holder 6. Yes. The second holder 107 has a protrusion 107a at the tip, but the first and second claw members 64 and 65, the first and second urging members 66 and 67, and the like are not provided. A small recess 111 into which the protrusion 107 a is fitted is provided on the bottom surface 12 of the recess 11 that engages with the second holder 107.

  FIGS. 15A and 15B are schematic views showing the attachment procedure of the winding device 103 of the present embodiment. FIGS. 15A and 15B are top views, and FIGS. 15C and 15D are side views. In the following description, the holding unit 10 that holds the first holder 6 is referred to as a first holding unit 10a, and the holding unit 10 that holds the second holder 107 is referred to as a second holding unit 10b. When attaching the winding device 103, first, as shown in FIG. 15A, the winding device 103 is tilted with respect to the Y direction, and the protrusion 107a of the second holder 107 is moved to the small recess 11 of the second holding portion 10b. Insert into. At the same time, the first holder 6 is moved downward as shown in FIGS. 15C and 15D while moving forward in the X direction as shown in FIGS. 15A and 15B, and FIG. The winding device 103 is rotated counterclockwise as viewed from the left side of a). Then, the 1st holder 6 is attached to the 1st holding | maintenance part 10a according to the above-mentioned procedure.

  In the present embodiment, the second holder 107 is not restrained by the holding unit 10 itself, but is indirectly restrained by the first holder 6. Therefore, the second holder 107 only needs to have a mechanism that can be positioned with the second holding portion 10b, and the structure is simplified. Further, the attachment can be performed with one hand as in the first embodiment, and the removal can be performed with one hand because only the switch member 68 of the first holder 6 has to be operated.

  Further, when the winding device 103 is attached to the vehicle, the spring 117 is compressed by a certain amount. From this state, a further compressible amount is a, and a wrap amount in the Y direction of the protrusion 107a and the small recess 111 is b. When this is done (see FIG. 14B), it is preferable that b be larger than a. By doing so, even if the spring 117 is compressed by the maximum amount, the engagement between the projection 107a and the small recess 11 is not released. Since the user does not forcibly remove the winding device 103 from the second holder 107 side, but removes it from the first holder 6 side, the damage to the winding device 103 during removal can be suppressed. it can.

  In the present embodiment, the protrusion 107a has a circular cross-sectional shape, but may be a polygon such as a square or a regular hexagon. By setting the cross-sectional shape of the protrusion 107a to a shape having a major axis and a minor axis such as a rectangle or an ellipse, the winding device 103 can be easily set in the correct direction. The protrusion 107a is not essential and can be omitted.
