  In Patent Document 1, when audio is attached in addition to the speed change operation device, for example, as disclosed in Patent Document 2, it is conceivable to attach audio to the rear end of a bracket welded to a steering member. In this case, the upper bracket and the lower bracket for mounting the speed change operation device are integrated by welding to the floor brace fastened and fixed to the vehicle floor, and the audio mounting bracket is attached to the steering member fastened and fixed to the dash side panel. Since it becomes the structure integrated by welding, it is difficult to obtain the installation accuracy (position accuracy) in the instrument panel of the audio and the speed change operation device.

  In view of the above facts, the present invention has an object to obtain an audio and transmission operation device mounting structure that can improve the installation accuracy (position accuracy) of the audio and the transmission operation device in the instrument panel.

According to the first aspect of the present invention, there is provided a mounting structure for an audio and a speed change operation device according to the present invention, which is disposed along the vertical direction of the vehicle and has a lower end fixed to the vehicle floor, and is integrally coupled to the floor brace. a shift bracket shift operating device disposed in the vehicle compartment front is attached, wherein disposed in the vehicle vertical direction upper side of the floor brace, Rutotomoni lower end integrally coupled to the upper end of the floor brace the floor An audio bracket to which audio is attached to the upper side of the upper end of the brace and an instrument panel that is fixed to the left and right vehicle body skeleton members at the vehicle width direction and arranged along the vehicle width direction in the front of the passenger compartment And instrument panel reinforcement to which the audio bracket is directly or indirectly fastened and fixed. And it has a.

According to a second aspect of the present invention, there is provided the audio and speed change operation device mounting structure according to the first aspect of the invention, wherein the floor brace is made of a pipe material, and the lower end of the floor brace is flattened. The audio bracket has a mounting portion formed with a mounting hole that is fastened and fixed to the vehicle floor, and the upper end of the floor brace is formed into a U-shaped cross section without being crushed. It is welded to the inner wall surface.
According to a third aspect of the present invention, there is provided the audio and transmission operating device mounting structure according to the first or second aspect, wherein the front end portion is fixed to the instrument panel reinforcement and extends to the rear side of the vehicle. The audio bracket is indirectly fastened and fixed to the instrument panel reinforcement via the bracket, and the upper end side of the floor brace and the audio bracket is inclined toward the front side of the vehicle.
According to a fourth aspect of the present invention, there is provided the audio and speed change operation device mounting structure according to the third aspect of the present invention, wherein the bracket has a rear end bent to the vehicle lower side to form a rear wall, A floor brace and the audio bracket are supported by the rear wall portion.

According to the first aspect of the present invention, the lower end portion of the floor brace arranged along the vehicle vertical direction is fixed to the vehicle floor, and the shift bracket is integrally coupled to the floor brace. A shift operating device is attached. In addition, an audio bracket is disposed on the upper side of the floor brace in the vehicle vertical direction, and the lower end of the audio bracket is integrally coupled to the upper end of the floor brace, and both ends in the vehicle width direction are fixed to the left and right body frame members.
