に弾性復帰する。PRIOR ART FIG. 9 is a perspective view of a typical prior art. On the front plate that constitutes the operating part of audio equipment for vehicles,
The operation button 1 is provided. The operation button 1 is connected to the support member 3 by a connecting piece 2. These operation buttons 1,
The connection piece 2 and the support member 3 are made of synthetic resin, for example. By pressing the operation button 1 with the fingers in the arrow A1 direction, the switching mode of the switch SW indicated by a virtual line provided on the back side of the operation button 1 can be changed. When the finger is released from the operation button 1 and the pressed state is released, the operation button 1 elastically returns to the initial position by the elastic force of the connecting piece 2.

の押圧操作によつて、連結片2に繰返し応力が発生し、
その繰返し応力によつて弾性回復力が低下したり、操作
釦1にがたつきを発生し、操作性が低下してしまう。If the length 1 of the connecting piece 2 is relatively long, the operation feeling when switching the switching mode of the switch SW is disturbed when the operation button 1 is pressed. Operation button 1
Repeated stress is generated in the connecting piece 2 by the pressing operation of
Due to the repeated stress, the elastic recovery force decreases, or the operation button 1 rattles, which deteriorates the operability.

形成されるため、その金型がアンダーカツトになつてし
まい、一度の成型で製造することができない。In order to solve such a problem, conventionally, the operation button 4 shown in FIG. 10 and a support member 5 having a substantially U-shape are individually formed, and the claw 6 of the operation button 4 is fitted to the support member 5. The operation button 4 is arranged and held in an arrangement hole formed in the front plate in a state of being fitted in the fitting recess 7. However, in such a prior art, when the operation button 4 is attached to the front plate and pressed in the direction of arrow A2, the lower surface of the operation button 4 is located on the lower surface of the arrangement hole into which the operation button 4 of the front plate is fitted. Since 8 is in sliding contact, operability is poor. Operation button 4
Is not supported downward (in the direction of arrow B1), the claw 6 may fall out from the fitting recess 7 of the support member 5, and the operation button 4 may drop. Further, when the support member 5 is manufactured, the inner surfaces 9a, 9b of the fitting recess 7 which face each other are formed such that the distance l2 becomes smaller toward the open end side, so that the die is undercut. It cannot be manufactured by molding once.

される。Embodiment FIG. 1 is a sectional view of an embodiment of the present invention. The switching means 20 for realizing the operation button structure of the present invention has an operation button 21 which is pressed in the direction of arrow C1 and a front plate 25. An arrangement hole 22 for the operation button 21 is formed in the front plate 25, and has an engaging portion 23 which is a recess extending from the peripheral edge portion of the arrangement hole 22 to the rear side (right side in FIG. 1). One side of the operation button 21 is coupled with a connecting piece 24 in the arrangement hole 22,
A protrusion 26 that engages with the engagement portion 23 is provided. The front plate
A substrate 27 is arranged on the back side of 25 (on the right side in FIG. 1), and a pressing switch 28 is provided on the substrate 27 so as to face the front plate 25 side. The pressing switch 28 has a pressing piece 30 that is pressed by a pressing protrusion 29 formed on the operation button 21. The pressing piece 30 is elastically biased toward the left side in FIG. 1 by a compression spring built in the pressing switch 28. Operation button
The outer peripheral surface of 21 and the inner peripheral surface of the arrangement hole 22 have a predetermined small gap d. Therefore, when the operation button 21 is pressed in the arrow C1 direction, the pressing protrusion 29 abuts against the pressing piece 30 and presses it, and the switching mode of the pressing switch 28 is switched. Switching means 20 having such a configuration,
For example, it is preferably implemented in an operation part of an audio device for a vehicle.

FIG. The operation button 21 has a substantially flat plate-shaped pressing portion 31 and frame portions 32a to 32d surrounding the pressing portion 31. The frame parts 32a to 32d
Is equal to the side of the operation button 21. In addition, the back surface 31 of the pressing portion 31
A rib 33 extending across the frame portions 32b and 32d is fixed to a. Two protrusions 26 are formed on the frame portion 32a, and a ridge 34 is formed on the other frame portions 32b, 32c, 32d so as to extend in the circumferential direction. The contact surface 38 of the ridge 34 is the arrangement hole 22 of the front plate 25
The operation button 21 is prevented from coming out forward (in the direction opposite to the arrow C1 direction) by coming into contact with the rear surface 25a in the vicinity. Therefore, when inserting the operation button 21 into the arrangement hole 22, the front plate 25

的に行うことができる。FIG. 6 is a sectional view of the front plate 25, FIG. 7 is a front view of the front plate 25 in the vicinity of the arrangement hole 22, and FIG. 8 is a sectional view taken along section line VIII-VIII of FIG. Is. With the operation button 21 mounted in the placement hole 22, the two projecting portions 26 are fitted and locked in the two engaging portions 23 corresponding thereto. In such a state, the protruding portion 26 is
The lower surface 36 in 23 prevents its downward displacement. Further, the lateral surface 37 of the engaging portion 23 prevents the lateral displacement thereof. In this way, the downward and lateral displacement of the operation button 21 can be prevented, and the operation button 21 can be held in the arrangement hole 22 without rattling, and a smooth button operation can be realized. At the same time, the operation button 21 can be prevented from falling off. Further, in the frame portion 32C of the operation button 21, the surface (see FIGS. 1 and 3) 38 facing the back surface 25a of the front plate 25 has the back surface 2
It comes into contact with 5a and its forward displacement is blocked. Therefore, it is possible to prevent the operation button 21 from falling off the arrangement hole 22. Further, since the frame portions 32a to 32d and the ridges 34 completely cover the arrangement hole 22, there is no risk of light leakage, and therefore the light emission display by the display areas 35a and 35b can be effectively performed.

It can be carried out. Furthermore, since the mold of the front plate and the operation button 21 of the present invention does not become an undercut,
It can be easily manufactured by molding once, and productivity can be improved. Further, since the side surface of the operation button 21 having the protruding portion 26 and the ridge 34 completely cover the arrangement hole, there is no risk of light leakage from the arrangement hole 22, and the internal illumination of the operation button 21 can be effectively performed. It can be carried out.
