DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a push button device according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a top view of a main part of one embodiment of a push button device according to the present invention, and FIG. 2 is a side sectional view of a main part of one embodiment of the push button device according to the present invention. FIG.
2, reference numeral 1 denotes a push button, 2 denotes an operation piece standing upright at four locations on the outer periphery of the lower surface of the push button 1, and 3 denotes a switch (tact switch or the like) mounted on a mounting plate 13 at a position corresponding to the operation piece 2. 4 is a panel arranged so as to surround the push button 1, 5 is a column standing at the center of the lower surface of the push button and having a sharply formed tip, and 11 is an outwardly curved shape on the outer periphery of the push button. A projection 12 is a wall surrounding the outer periphery of the push button 1 and is formed by setting up a rib inside the panel 4. A projection 14 is formed on the mounting plate 13 at a position corresponding to the center of the column 5. It is an established hole.

[0007] The push button 1 is loosely fitted with a hole 14 formed at a position corresponding to the center of the push button 1 of the mounting plate 13 at an acute angle of the tip of the column 5 on the lower surface. At the same time, the tip of the curved protruding piece 11 provided on the outer peripheral part of the push button 1 is brought into contact with the upper corner of the wall surface 12 of the panel 4 surrounding the push button 1, The position balance with respect to the panel 4 is maintained by the elasticity (spring property) of 11. As a result, the push button 1 is pressed downward by the elasticity of the protruding piece 11, and the push force of the push button 1 upward is applied to the tip of the support post 5, so that the push button 1 does not rattle at a predetermined position (FIG. 2). ), And further, for example, the panel 4
When the push button 1 is supported horizontally by the projecting piece 11, the position of the push button is not lowered, and the center of the panel 4 is not displaced. .

The push button 1 has a pressing surface (upper surface) in any direction of the arrow shown in FIG. 1 (for example, the direction of the arrow A in FIG. 2).
If you push it in such a way that it is inclined to
11 bends, the operating piece 2 is lowered, and the switch 3 is pressed by the tip to operate. At this time, since the push button 1 has the tip of the column 5 loosely fitted into the hole 14 of the mounting plate 13, the tip of the operating piece 2 does not shift from the position of the switch 3.
Press firmly. When the push button 1 is tilted, the push button 1 does not wobble because the right protruding piece extends and is supported by the wall surface 12 of the panel 4. When the pressing on the pressing surface is released, the push button 1 returns to the original position (the state in FIG. 2).

The protruding piece 11 may be formed integrally with a synthetic resin or the like for forming the push button 1, or may be made of a metal spring material having elasticity, synthetic rubber having cushioning properties and appropriate hardness, or synthetic resin ( For example, it may be formed separately using urethane foam, foamed polyethylene, etc.), connected to the push button mounting side in a ring shape, fitted into the push button 1, and fixed at the position shown in FIG.

[0010]

As described above, according to the pushbutton device of the present invention, the center position of the pushbutton is determined when the pushbutton is operated because the tip of the column is loosely fitted in the hole of the switch mounting plate. Since it is supported at the center position by being supported by a curved protruding piece having elasticity formed on the outer peripheral portion, there is no backlash in a state where the push button is mounted, and even in a structure in which the push button is turned sideways, No deviation occurs, and
This is a useful one that does not require a member such as a holding plate for mounting the push button.
