[Assembling Method of First Embodiment] Next, an assembling method of the air conditioner operation panel 1 of the present embodiment will be briefly described with reference to FIGS.

First, the upper end of the printed wiring board 6 in which the printed circuit 20 including the fixed contacts 21 is formed on both sides is shown in FIG.
The rubber sheet 7 is placed on the printed wiring board 6 so as to be covered with the rubber sheet 7 having the movable contact 25 built in the contact part 24. At this time, the contact plate 18 may be joined to the contact portion 24 of the rubber sheet 7 or the contact plate 18 may be joined to the contact portion 24 in advance.

Next, after assembling the reflector 9 on the printed wiring board 6 with a predetermined gap therebetween, the pressing surface 4 of the pressing knob 5 is turned upward from the front side of the concave side wall 14 to the pressing knob 5. The extension 17 of the reflector 9 through hole 2
9, the concave side wall 14 is fitted to the outer periphery of the convex side wall 27 of the reflector 9 while passing through the rail 1.
6, 28 are fitted together. Thereby, the pressing knob 5
Is mounted on the outer periphery of the convex side wall 27 of the reflector 9. This assembling operation is performed by the number of the pressing knobs 5, and further, other components such as a liquid crystal display device and a volume switch are assembled at a predetermined position of the reflector 9.

Next, the front case 3 is placed on the upper end surface of the reflector 9 with a predetermined gap therebetween so that the concave side wall 14 of the pressing knob 5 fits into the mounting hole 12 of the front case 3 so that the air conditioner can be operated. The assembly of the operation panel 1 is completed. At this time, the pressing knob 5 is
With the pressing surface 4 slightly protruding from the display surface 2 of FIG. In addition, the upper end surface of the fitting claw 15, which is partially protruded from the concave side wall 14 of the pressing knob 5, is locked to the regulating portion 13 of the mounting wall 11 of the front case 3. Is in contact with the contact plate 18. Therefore, the pressing knob 5 and the movable contact 25 built in the contact portion 24 are arranged so as to be interlocked.

Here, when replacing the pressing knob 5 with a new one, even if the air conditioner operation panel 1 is mounted on the vehicle body side, the pressing knob 5 can be easily pressed by removing only the front case 3 from the reflector 9. The knob 5 can be replaced. When replacing the indicator device or the lamp 8 with a new one, the indicator device or the lamp 8 can be easily replaced by removing the front case 3 and the pressing knob 5 after removing the air conditioner operation panel 1 from the vehicle body side. be able to.

[Operation of First Embodiment] Next, the operation of the air conditioner operation panel 1 of the present embodiment will be briefly described with reference to FIGS.

In this embodiment, the convex side wall 27 of the reflector 9 is fitted so that the rail 28 formed on the outer peripheral surface of the convex side wall 27 and the rail 16 formed on the inner peripheral surface of the concave side wall 14 are fitted. A pressing knob 5 is inserted between the outer periphery of the front case 3 and the inner periphery of the mounting wall 11 of the front case 3 so as to be freely retractable.
Thus, when the operator presses the pressing surface 4 of the pressing knob 5 with a finger, the pressing knob 5 is guided by the rail 28 and displaces downward (in the pressing direction) in FIG.

At this time, even if no pressing force is applied, the distal end of the extension 17 of the pressing knob 5 is always in contact with the contact plate 18.

When the contact plate 18 is displaced downward in the drawing, the contact portion 24 of the rubber sheet 7 is bent downward in the drawing, and as shown in FIG. 5B, the movable contact 25 built in the contact portion 24 is moved. Fixed contact 2
By touching 1, an electric signal (ON signal) output to the air conditioner control device (not shown) is generated.

When the operator releases his / her finger from the pressing surface 4 of the pressing knob 5, the contact portion 24 returns to a convexly bulging state due to the elastic force of the rubber sheet 7, so that the contact plate 18 is pressed.
Is displaced upward in the figure. When the contact plate 18 is displaced upward in the drawing, the concave side wall 14 is guided by the rail 28 and displaced upward in FIG. At this time,
The fitting claw 15 of the pressing knob 5 is connected to the regulating portion 1 of the front case 3.
At the stage where the pressing knob 5 is locked, the pressing knob 5 returns to the initial position,
The pressing surface 4 is held in a state where it slightly protrudes from the display surface 2 of the front case 3. When the pressing knob 5 is returned to the initial position, the movable contact 25 is separated from the fixed contact 21 as shown in FIG. 5A, so that the generation of the electric signal stops (the OFF signal is generated).
