In the switch mounting structure for a vehicle shown in FIG. 5, the switch body 20 can be easily mounted on the mounting member 10 by fitting, but it is difficult to remove.

  An object of the present invention is to solve such a problem, and an object of the present invention is to provide a switch mounting structure for a vehicle that can improve the workability of attachment and detachment.

The present invention is for achieving the above object, and is configured as follows.
The invention described in claim 1
A switch mounting structure for a vehicle in which a switch member included in a switch main body is fitted into a switch mounting hole provided in a vehicle mounting member and the switch main body is mounted on the mounting member. A flange that closes a gap generated in the switch mounting hole in a state where the switch member is fitted in the switch mounting hole, and a flange that hangs downward at a peripheral edge of the flange and protrudes from a hole diameter of the switch mounting hole and is elastic And at least a pair of opposing locking claws that are movable inward of the hole diameter by deformation. Further, a notch groove is provided from the upper surface of the flange toward the locking claw, and a tapered portion having a downward slope is formed at the tip of the notch groove toward the outside.

  According to this configuration, when the switch member is fitted into the switch mounting hole, each locking claw is pressed by the inner peripheral surface of the switch mounting hole and bent inward of the hole diameter. When the switch member is fitted into the switch mounting hole until the lower surface of the flange of the switch body contacts the upper surface of the mounting member, each locking claw is not pressed by the inner peripheral surface of the switch mounting hole and returns to the state before the fitting. Moreover, when it will be in this state, the lower surface of an attachment member and the extending surface a of a latching claw will contact | abut. Therefore, the switch body can be mounted on the mounting member by sandwiching the mounting member between the flange and the locking claw and locking it. Further, when removing, for example, a flathead screwdriver or the like is inserted into the notch groove from the upper surface of the flange, and the tapered tip portion of the notch groove is pushed downward at the tip. Then, the locking claw bends inward of the switch mounting hole and does not protrude with respect to the hole diameter of the switch mounting hole so that the locking is released, so that the switch body can be removed from the mounting member. Thus, even if the switch body has a flange, it can be easily attached to and detached from the attachment member.

Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a switch mounting structure for a vehicle according to the present invention. 2 shows a cross-sectional view taken along line AA in FIG. 1, (A) shows a state before the switch body 20 is mounted, (B) shows a state during the mounting of the switch body 20, and (C). Indicates a state after the switch body 20 is mounted. 3 shows a cross-sectional view taken along the line A-A in FIG. 1, (A) shows a state before the switch body 20 is removed, and (B) shows a state where the switch body 20 is being removed.

First, the mounting member 10 and the switch body 20 will be described with reference to FIG.
As shown in the drawing, the mounting member 10 is provided with a switch mounting hole 11 penetrating in the vertical direction. Further, the switch body 20 has a switch member 21 having an operation portion 21a that is operated by pressing on the surface, and the switch member 21 is generated in the switch attachment hole 11 in a state where the switch member 21 is fitted into the switch attachment hole 11 at the peripheral portion thereof. A flange 22 for closing the gap is provided. In addition, a pair of locking claws 23, 23 that hang downward at the peripheral edge of the flange 22 are provided so as to face each other. The locking claws 23, 23 have a curved surface 23 b so as to protrude outward from the lower end portion, and are formed to protrude with respect to the diameter of the switch mounting hole 11.

  The locking claws 23 and 23 are integrally formed of a rigid synthetic resin together with the flange 22 and are movable by an elastic action, that is, flexible enough to be elastically deformed. Further, the distance from the lower surface of the flange 22 to the projecting surface 23a of the locking claw 23 (L in FIG. 1) and the height of the inner peripheral surface of the switch mounting hole 11 (H in FIG. 1) coincide. To do. Further, notch grooves 24 and 24 are provided from the upper surface of the flange 22 toward the locking claws 23 and 23. A tapered portion 24a having a downward slope is formed at the front end portion of the cutout grooves 24, 24 in the outward direction.

  Next, a method for mounting the switch body 20 to the mounting member 10 will be described with reference to FIG. As shown in FIG. 2A, the switch member 21 of the switch body 20 is fitted from above the switch mounting hole 11 of the mounting member 10. Then, as shown in FIG. 2 (B), each of the locking claws 23, 23 of the switch body 20 protrudes with respect to the diameter of the switch mounting hole 11, so that the protruding curved surface 23 b has an inner periphery of the switch mounting hole 11. The surface is pressed and pushed inward (center direction) of the switch mounting hole 11 by elastic deformation.

  2C, when the switch member 21 is fitted into the switch mounting hole 11 until the lower surface of the flange 22 of the switch body 20 contacts the upper surface of the mounting member 10, each locking claw 23 of the switch body 20 is provided. , 23 is not pressed by the inner peripheral surface of the switch mounting hole 11, and the locking claws 23, 23 return to the state before being fitted by elastic deformation. In this state, the lower surface of the mounting member 10 and the protruding surface 23a of the locking claw 23 come into contact with each other. Thus, the switch body 20 can be mounted on the mounting member 10 by sandwiching and mounting the mounting member 10 between the flange 22 and the locking claws 23, 23.

  Next, a method for removing the switch body 20 from the mounted state shown in FIG. 2C will be described with reference to FIG. As shown in FIG. 3A, the flathead screwdriver 30 is inserted from above the cutout groove 24. Then, as shown in FIG. 3B, the tip of the flathead screwdriver 30 is pushed downward into the tip 24a of the cutout groove 24. Then, the locking claw 23 bends inward of the switch mounting hole 11 and does not protrude with respect to the diameter of the switch mounting hole 11 so that the locking is released, so that the switch body 20 can be removed from the mounting member 10. The cutout grooves 24 and 24 need only be capable of inserting at least the tip of the flat-blade screwdriver 30, and the depth (D in FIG. 1) may be shallow and the width (W in FIG. 1) may be narrow. Also good.

  As described above, each of the locking claws 23 and 23 is easily and independently bent, so that the switch member 21 can be fitted into the switch mounting hole 11 with a light force. In addition, since each of the locking claws 23 and 23 is also a rigid resin having rigidity, when it is fitted and locked as described above, a feeling of moderation is obtained, and the operating portion 21a of the switch body 20 faces downward. Even if it becomes, the retention strength of the switch main body 20 with respect to the attachment member 10 is fully ensured. Further, since the switch body 20 has the flange 22, the gap generated in the switch mounting hole 11 can be closed, and the waterproofness and dustproofness can be improved.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the embodiment, an example in which the locking claws 23 and 23 are a pair has been described. However, the present invention is not limited to this, and two pairs may be used. In that case, for example, the locking claws 23 are provided not only in the left-right direction but also in the front-rear direction in FIG.
