【The invention's effect】
According to the present invention, since the operation buttons are provided so as to protrude and retract from the operation panel surface of the in-vehicle device, the operation buttons on the front panel retract and flatten when not in use. It becomes difficult to recognize that it is a device. Therefore, it is assumed that no on-vehicle audio equipment is mounted, and an anti-theft effect is obtained.
[0038]
Further, since the front end operation surface of the operation button is flush with the operation panel surface when retreating, the protrusions are eliminated, and the safety of the passenger is improved.
Further, since the tip surface of the operation button protrudes from the operation panel surface when protruding, it can be used in the same manner as a normal vehicle-mounted device when used.
[0039]
Furthermore, since the operation panel and the operation button are covered with a flexible member, the positions of the operation panel and the operation button are not known when the operation button is retracted.
In addition, since the operation panel and the front end operation surface of the operation button are composed of the same color, it is extremely difficult to identify when the front end of the operation button is retracted.
