That is, the clip member 45 comprises a head 45a and a pair of locking legs 45b projecting from one side surface of the head 45a at a predetermined interval.
The protruding ends of b are connected to each other close to each other. An outwardly protruding locking portion 45c is formed at an intermediate position in the lengthwise direction of each locking leg 45b.

Then, as shown by the phantom line, when the protruding ends of the both locking legs 45b of the clip member 45 are pushed into the fixing member fitting holes 43 on the mounting portion 24 side, the two locking portions 4 are formed.
The two locking legs 45b are each bent inwardly and deformed so as to be close to each other so as to be close to each other, and are sequentially fitted. When the locking legs 45b pass through the fixing member fitting holes 44 on the mounting bracket 28 side, they return elastically, and As shown in the figure, a fixed state is obtained in which the locking portions 45c are locked in the peripheral portion of the fixing member fitting hole 44 of the mounting bracket 28 in a retaining manner.

At this time, since the weight of the on-vehicle unit 11 is supported on the holding rod 27 side, a large load does not act on the clip member 45 side, and no trouble occurs.

Therefore, if the method of fixing with the clip member 45 is adopted, as compared with the above-mentioned bolt 29 fastening method, it is only necessary to simply press-fit, so that the assembling workability can be further improved.

The clip member 45 has a structure in which the locking portions 45c of the both locking legs 45b are elastically restored and are locked and prevented from being pulled out.
The clip member is not limited to the shape and the structure of the embodiment as long as it is a clip member of a type that is push-fitted into 3, 44 and is retained and locked by elastic return, and is used for fixing a general interior material of a vehicle. A structure using a known clip member having the above structure may be used.

Further, in each of the above embodiments, the structure is shown in which the connection connector 25 for supplying power to each unit such as the radio mounted on the on-vehicle unit 11 is integrated in one place. The connector 25 may be configured to protrude therefrom. When assembling each unit such as a radio to the in-vehicle unit 11, a method may be used in which each unit is independently and individually assembled.
8 and the operation input keys 21 may be combined and used.

The positions of the mounting portions 24 and the connection connectors 25 in the on-vehicle unit 11 are also different from those of the casing 12.
The position of each embodiment is not limited at all.
