According to the mounting structure of the audio device 2 having such a configuration, when assembling the audio device 2, the pin 27 and the bush on the audio device 2 side are provided on the flange portion α of the flange 18 a of the support members 16 a and 16 b. 28
The bush 28 is slid while the support member 1 is
The flange portion α may be used as a guide for the pin 27 and the bush 28 since the flange portion α may be engaged (contacted) with the flange portion β of the flange 18a of 6a, 16b. Therefore, the audio device 2 can be easily and surely moved to a predetermined assembly position without being supported by a hand or the like, and can be mounted.

A pair of support members 16 fixed to the steering support member 3 hold the audio equipment 2.
Since it is performed with a single member (a, 16b) (a single member to which no other member is attached other than the plate-like member), the assembling accuracy of the audio device 2 can be improved.

In addition, since the position for supporting the audio device 2 has been changed from the center of the conventional rear end surface to both side surfaces 16a and 16b, the audio device 2 is mounted independently of the rear end surface 2c of the audio device 2. Therefore, there is no restriction on the rear end face 2c. More specifically, the size (length of the depth) of the audio device 2 and the position where the wire harness 31 (see FIG. 2) is pulled out are not restricted at all, and the degree of freedom for these is improved. it can. Therefore, it is possible to attach various types of audio equipment 2 as needed.

Since it is offset in the vehicle width direction, the pin of the bracket 23 and the free end portion 24 serving as the bush mounting portion are easily deformed when an impact is applied. Therefore, when an excessive impact force acts on the audio device 2 in a direction indicated by an arrow F in FIG. 6 (a direction toward the front of the vehicle body), the flange 23 bends at the bending point M as shown in FIG. The impact energy can be absorbed by bending. Therefore, it is possible to provide an impact energy absorbing function without lowering the rigidity of the bracket 23 holding the audio device 2, and it is possible to provide a structure effective against vibrations caused by running of the vehicle.

Further, since the rubber bush 28 is mounted on the pin 27, the work of assembling the audio equipment 2 is facilitated and the vibration after the installation of the audio equipment 2 is prevented. Can be. That is, when the pin 27 is slid on the flange portion α of the bracket 23 without mounting the bush 28, the sliding occurs in a state in which the metals are rubbed, and smooth sliding cannot be performed. Even after the audio device 2 is mounted, a vibration sound (metal sound) is generated between the metal of the pin 27 and the flange portion β of the bracket 23 as the vehicle travels. If the bush 28 is mounted on the flange portions α, β
The bush 28 and the bush 28 are in contact with each other with a metal material and a rubber material, so that the bush 28 can be smoothly slid on the flange portion α when the audio device 2 is mounted, and the audio device 2 is mounted. It is possible to effectively prevent the generation of vibration noise later.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment.
Various modifications and changes are possible based on the technical concept of the present invention. For example, in the above-described embodiment, the audio device 2 is attached to the steering support member 3. However, various in-vehicle devices (such as a wireless receiver and an electronic control device) other than the audio device 2 may be attached to the steering support member 3. The present invention is also applicable to a case where the present invention is attached to a vehicle body strength member.

Since the in-vehicle device can be used as a guide, it is not necessary to support the in-vehicle device with a hand or the like. Therefore, the in-vehicle device can be easily and quickly assembled at a designated position, and the mounting workability can be improved. In addition, with the provision of the guide flange on the support member, the presence of the flange can improve the strength (rigidity) of the support member itself, and can prevent the vibration of the on-vehicle equipment during running of the vehicle.

According to a fourth aspect of the present invention, a bracket is attached to both sides of a vehicle-mounted device, and a pin and a bush are attached to a free end provided at a tip end of the bracket, and a flange of a support member (for example, The locking portion (for example, the locking portion W shown in the above-described embodiment) for locking the pin and the bush is provided on the flange portion β) shown in the above-described embodiment. When an excessive impact force is applied to the on-vehicle device, the free end is deformed (bent), and accordingly, the impact energy is effectively absorbed. Therefore, according to the mounting structure of the present invention, impact energy can be absorbed without lowering the strength (rigidity) of the bracket.

Further, according to the present invention, the locking portion of the support member is constituted by a flange inclined with respect to the axis of the pin and the bush, and the tip of the flange forming the locking portion, the bush, When the excessive impact force is applied to the in-vehicle equipment, the contact point of the bracket and the broken point of the free end of the bracket on which the pin and the bush are arranged are offset in the vehicle width direction. In addition, the deformation of the free end of the bracket starts from the bent portion, so that the impact energy can be absorbed. Further, the presence of the offset makes it possible to arrange the pin at a position distant from the side surface of the in-vehicle device, and has a structure that is advantageous against vibration during vehicle running.
