Although the first embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the first embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Even this is included in the present invention.

For example, in the first embodiment, the opening peripheral portion 17a is supported from below by the horizontal support portions 35b, 35b of the pair of left and right audio brackets 35, 35, but is not limited thereto. Even if the audio unit 103 is supported only by the opening peripheral portion 17 a of the instrument panel 17, a horizontal arrangement provided above the steering member body 20 and above the support stay 21. What is necessary is just to have a surface part.

[0082]

As described above, according to the first aspect of the present invention, both ends of the steering member main body are fixed to both sides of the vehicle body, and the vehicle body floor panel is substantially in the vehicle width direction. The upper end surface of one support stay that stands substantially vertically upward from the floor mounting portion provided at the center is abutted and fixed to the lower surface of the substantially central portion of the steering member body.

For this reason, even with one support stay,
Vibration in the direction along the vertical direction substantially at the center of the steering member body is effectively received and suppressed by the upper end surface of the support stay.

Further, since the floor mounting portion is located at a position offset to the front of the vehicle from the center line of the support stay, the foot space expands in the front of the vehicle as well as in the vehicle width direction. , A walk-through area and the like can be easily secured, and the adaptability to a change in vehicle type is good.

According to the second aspect of the present invention, since the support stay is constituted by the stay main body having a substantially closed cross-sectional structure, even if only one support stay is used, the steering member main body can be used. It is possible to obtain sufficient rigidity to sufficiently absorb vibration in the direction along the vertical direction at the substantially central portion.

[0086] According to the third aspect,
Using the upper end surface of the stay outer member, the upper end surface of the support stay that is in contact with the lower surface of the substantially central portion of the steering member body can be easily formed.

Further, by attaching a stay inner member to the flange portion of the stay outer member, a substantially closed cross-sectional structure of the stay main body can be easily formed, and the stay inner member is joined together with the flange portion. By fixing to the steering member main body, the rigidity of the support portion can be further improved.

Further, according to the fourth aspect of the present invention, electronic equipment is mounted on the horizontal arrangement surface provided above the steering member body and above the support stay. Since the horizontal mounting surface extends in a substantially horizontal direction, the load of the electronic equipment acts on the horizontal mounting surface only in a substantially vertical direction and is received.
For this reason, for example, by the instrument panel,
Even when the horizontal arrangement surface portion is configured, the load acts only in one vertical direction, and the bending moment is taken into account without generating a lateral component force as in the case of being mounted diagonally. No structure is required. Therefore, the structure is simplified, the number of parts is reduced, and an increase in manufacturing cost can be suppressed.

According to the fifth aspect of the present invention, the electronic equipment load from each of the equipment mounting points is dispersed in the vehicle front-rear direction from the center of gravity of the electronic equipment, and the horizontal arrangement is performed. It is conveyed to the face. Since the horizontal arrangement surface is supported from below by a pair of left and right device mounting stays, for example, the load input to the instrument panel is further reduced.

Further, the equipment mounting stay is integrally fixed to the upper portion of the steering member body whose vibration is suppressed by the support stay, and furthermore, the horizontal installation surface portion which is hardly affected by bending moment is provided. Since it is only necessary to support the device from below, a lightweight and simple structure may be used, and furthermore, an increase in manufacturing cost can be suppressed.

[0091] According to the sixth aspect,
Since the air-conditioner unit avoiding portion formed on the support stay and the vehicle interior-side equipment avoiding portion are formed so as to be substantially S-shaped when viewed from the side of the vehicle, and are formed so as to be substantially perpendicular to each other. Even if the space is expanded, the air conditioner unit can be arranged with good space efficiency.

Further, since the position of the steering member body in the vehicle front-rear direction can be located substantially directly above the center line of the support stay, the support balance is improved and the support efficiency is further improved.

According to the seventh aspect of the present invention, since the center of gravity of the electronic equipment is provided almost directly above the floor mounting portion, a rotational moment is generated at the floor mounting portion. do not do. For this reason, since a structure that supports a load in a substantially vertical direction may be employed for the floor mounting portion, the structure is simplified, the number of parts is reduced, and
This has a practically useful effect of suppressing an increase in manufacturing cost.
