Description of the Related Art Conventionally, in-vehicle devices such as tape players and disk players are mainly fixed in a car, but today, with the increase in car crimes, the main body of the device is removed from the car. Things that can be done have been required. If the device itself can be removed from the car in this way, for example, even if the user leaves the car for a long time, the device itself can be removed and stored in a safe place, so that damage due to theft etc. can be prevented beforehand. Can be prevented.

[0003] However, it is troublesome to remove and attach such a device main body itself, and transporting the device itself is also a difficult task. Focusing on this point,
A device in which only the operating device can be removed from the nose of the device body has been put to practical use. If only the operating device is removed in this manner, the device main body cannot be operated without this operating device, and therefore cannot be used even if the device main body itself is stolen. Thereby, the theft of the device main body can be prevented.

FIG. 5 shows an example in which the operating device and the device main body are separated as described above. FIG. 5 is an exploded perspective view of a conventional in-vehicle device in which the operating device and the device main body are separated. The in-vehicle device shown in FIG. 1 includes a device main body 1 such as a disc player and an operating device 2 which is detachably formed on a mounting surface 1a of the device main body 1 so as to be detachable. The operation device 2 includes an operation button (not shown) and a display window 2b.

6B, the operating device 2 is elastically pressed by the spring 7 shown in FIG. Since this pressing force acts intensively on the connector 6 of the operating device 2, the circuit board 3 and the case 2e fixed to the circuit board 3 by this elastic pressing force as shown in FIG. Thus, the position where the connector 6 is provided is curved into a concave shape. When such bending occurs, the connection between the connectors 5 and 6 becomes non-uniform for each terminal, and not only a poor connection occurs, but also the groove 2 of the operating device 2 shown in FIG.
d and 2d are disengaged from the locking members 1c and 1c of the device main body 1, which causes a problem that the operating device 2 is easily detached from the device main body.

Accordingly, an object of the present invention is to prevent the operation device from being deformed even when a partial pressing force is applied to the operation device by press-fitting a connector between the operation device and the main body. And
