  The retainer 32 includes a front plate portion 321, a rear plate portion 322, a horizontal plate portion 323, a recess 324, a claw 325, a hole 326, and a claw 327. For example, the front plate portion 321 is orthogonal to the axial direction of the housing member 31. The front plate portion 321 has a surface in a direction orthogonal to the moving direction of the connecting member 2. The moving direction of the connecting member 2 is a direction in which the connecting member 2 moves in an operation that fulfills the function of the connecting member 2, for example, a direction in which the connecting member 2 moves between the change lever 1 and the transmission when a gear change occurs. is there. The front plate portion 321 contacts the surface of the bracket 33 on the change lever 1 side.

  The rear plate portion 322 is parallel to the front plate portion 321. The rear plate portion 322 has a surface in a direction orthogonal to the moving direction of the connecting member 2. The rear plate portion 322 contacts a surface of the bracket 33 opposite to the surface on the change lever 1 side. The horizontal plate portion 323 is provided at the upper ends of the front plate portion 321 and the rear plate portion 322 so as to be orthogonal to the front plate portion 321 and the rear plate portion 322. The lateral plate portion 323 contacts the surface of the bracket 33 on the side where the housing member 31 is inserted.

  The recess 324 is a recess for inserting the housing member 31. Specifically, the groove 311 of the housing member 31 is inserted into the recess 324. The recess 324 is provided in the front plate portion 321 and the rear plate portion 322. The claw 325 is a claw for fixing the housing member 31 to the retainer 32. The claw 325 is made of metal having elasticity. A plurality of claws 325 are provided near the upper end of the front plate portion 321.

  The claw 325 is provided on the front plate portion 321 so as to protrude from the rear plate portion 322 toward the front plate portion 321. Specifically, the claw 325 starts from the axis in the front plate part 321, and the tip part opposite to the axis of the claw 325 is located on the opposite side to the rear plate part 322 of the front plate part 321. Further, the front plate 321 is provided with a predetermined angle and inclination.

  When the housing member 31 is inserted into the recess 324, the outer peripheral surface of the housing member 31 comes into contact with the plurality of claws 325 while the housing member 31 is sandwiched between the plurality of claws 325. In this state, when the housing member 31 is to be removed from the retainer 32, the housing member 31 is hooked on the plurality of claws 325, and the housing member 31 is not separated from the retainer 32. In this way, the housing member 31 is fixed to the retainer 32.

  The hole 326 is a hole in which a claw 327 is provided on one side of the inner surface of the hole 326. The hole 326 is provided at a position farther from the horizontal plate portion 323 than at the position where the claw 325 is provided in the front plate portion 321. A plurality of holes 326 are provided in the front plate portion 321. The hole 326 has a rectangular shape, but the shape of the hole 326 is arbitrary.

  The claw 327 is a claw for fixing the retainer 32 to the bracket 33. The claw 327 is made of metal having elasticity. The claw 327 is formed, for example, by bending a plate-like member in the hole 326. For example, the claw 327 extends in a direction different from the front plate portion 321 starting from one side of the hole 326.

  In the first embodiment, the claw 327 functions as a contact portion that comes into contact with the recess 332 formed in the bracket 33. The claw 327 includes a first inclined plate portion 3273, a curved portion 3274, and a second inclined plate portion 3275.

  The first inclined plate portion 3273 is provided on the front plate portion 321 so as to extend from the front plate portion 321 toward the rear plate portion 322. The first inclined plate portion 3273 is provided to be inclined at a predetermined angle with respect to the front plate portion 321. The curved portion 3274 is provided at the end portion of the first inclined plate portion 3273 opposite to the end portion on the front plate portion 321 side. The second inclined plate portion 3275 is provided at the end of the bending portion 3274 opposite to the side where the first inclined plate portion 3273 is provided. The second inclined plate portion 3275 is inclined with respect to the front plate portion 321 by a predetermined angle, and the end portion of the second inclined plate portion 3275 is the tip of the claw 327.

  The retainer 32 is attached to the bracket 33 so as to sandwich the bracket 33 between the front plate portion 321 and the rear plate portion 322 of the retainer 32. When the retainer 32 is attached to the bracket 33, the claw 327 is positioned inside the recess 332 of the bracket 33. In this state, when the retainer 32 is to be removed from the bracket 33, the claw 327 of the retainer 32 comes into contact with the upper surface 3321 of the inner surface of the recess 332 of the bracket 33, and the retainer 32 is not separated from the bracket 33. . In this way, the retainer 32 is fixed to the bracket 33.

  When the driver operates the change lever 1 while the retainer 32 is fixed to the bracket 33, the connecting member 2 moves, and the retainer 32 moves slightly. At this time, the claw 327 is in contact with the inner surface of the recess 332 formed in the bracket 33 on a part of the upper surface other than the tip of the claw 327 extending obliquely from the front plate portion 321.

  However, at this time, a portion other than the tip of the claw 327 comes into contact with the upper surface 3321 of the inner surface of the recess 332. For example, as shown in FIG. 4, the claw 327 comes into contact with the inner surface of the concave portion 332 formed in the bracket 33 in the curved portion 3274. At this time, when the driver operates the change lever 1, the curved portion 3274 of the claw 327 comes into contact with and interferes with the upper surface 3321 of the inner surface of the recess 332. The frictional force between the curved portion 3274 and the upper surface 3321 is smaller than the frictional force between the tip of the plate member (for example, one side of the plate member) and the upper surface 3321. As a result, noise generated when the claw 327 contacts and interferes with the inner surface of the recess 332 can be reduced.

[Effects of the fixing structure 3 according to the first embodiment]
The fixing structure 3 according to the first embodiment is fixed to the moving body, a retainer 32 that fixes a housing member 31 that houses a connecting member 2 for connecting a plurality of members used in the moving body, and And a bracket 33 for fixing the retainer 32. The retainer 32 includes a front plate portion 321 having a surface in a direction orthogonal to the moving direction of the connecting member 2, and a claw 327 that contacts the recess 332 formed in the bracket 33. The claw 327 comes into contact with the inner surface of the recess 332 formed in the bracket 33 on a part of the upper surface other than the tip of the claw 327 extending obliquely from the front plate portion 321.

  Since the fixing structure 3 according to the first embodiment has such a configuration, it is possible to reduce noise caused by the interference between the claw provided in the retainer and the hook recess for claw provided in the bracket.

<Second Embodiment>
FIG. 6 is a diagram illustrating a configuration of the retainer 32a in the fixing structure 3 according to the second embodiment.
FIG. 6A is a view in which the retainer 32 in FIG. 2 is replaced with a retainer 32a and viewed in the X direction. FIG. 6B is a cross-sectional view taken along line XX of FIG.

  The retainer 32a differs from the retainer 32 in that it has a hole 326a and a claw 327a. Similar to the hole 326, the hole 326a is a hole in which a claw 327a is provided on one side of the inner surface of the hole 326a. The hole 326a is provided in the front plate portion 321 similarly to the hole 326. A plurality of holes 326 a are provided in the front plate portion 321. The hole 326a has a rectangular shape, but the shape of the hole 326a is arbitrary.

  Like the claw 327, the claw 327 a is a claw for fixing the retainer 32 a to the bracket 33. The claw 327a is made of metal having elasticity. The claw 327a extends, for example, in a direction different from the front plate portion 321 starting from one side of the hole 326a. In the second embodiment, the claw 327 a functions as a contact portion that comes into contact with the recess 332 formed in the bracket 33.

  The claw 327a has a first inclined plate portion 3273a and a vertical plate portion 3276a. The first inclined plate portion 3273a extends from the front plate portion 321 toward the rear plate portion 322 on the front plate portion 321 and is inclined with respect to the front plate portion 321 by a predetermined angle. The end of the first inclined plate portion 3273a opposite to the end on the front plate portion 321 side protrudes from the inside of the hole provided in the rear plate portion 322 to the outside of the retainer 32a. The vertical plate portion 3276a is provided at the end of the first inclined plate portion 3273a opposite to the front plate portion 321 side. The vertical plate portion 3276 a is parallel to the front plate portion 321 and the rear plate portion 322.

  When the driver operates the change lever 1 while the retainer 32a is fixed to the bracket 33, the connecting member 2 moves, so that the retainer 32a moves slightly. At this time, the claw 327a comes into contact with the inner surface of the concave portion 332 of the bracket at a part of the upper surface other than the tip of the claw 327a extending in an oblique direction from the front plate portion 321 (that is, the end of the vertical plate portion 3276a).

  Specifically, for example, as shown in FIG. 6, when the driver operates the change lever 1, the claw 327 a comes into contact with the inner surface of the recess 332 formed in the bracket 33 in the first inclined plate portion 3273 a. As a result, when the retainer 32a moves, the claw 327a and the upper surface 3321 of the inner surface of the recess 332 of the bracket 33 come into contact and interfere with each other.

  However, at this time, the claw 327a comes into contact with the plane of the first inclined plate portion 3273a of the claw 327a. As a result, noise generated when the claw 327a contacts and interferes with the inner surface of the recess 332 can be reduced.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention. For example, in the above description, the example in which the fixed structure 3 is provided in the vehicle has been described. However, the fixed structure 3 may be provided in a moving body other than a vehicle such as an aircraft or a ship.

  In the first and second embodiments, the claw 325 and the claw 327 are provided on the front plate 321, but the claw 325 is provided on the front plate 321, and the claw 327 is provided on the rear plate. The portion 322 may be provided. Further, the claw 325 may be provided on the rear plate portion 322, and the claw 327 may be provided on the front plate portion 321.
