Abstract

PURPOSE:To suppress the vibration of the whole air box main body so as to reduce vibration noise by fixing a bulk head in a cross member and disposing a wiper bracket for supporting a wiper unit inside the air box main body. CONSTITUTION:The vibration of a steering post at the running time of a vehicle is transmitted to a cross member 24 from a steering post bracket 30, but this vibration is suppressed as a bulk head 31 and a wiper bracket 32 are disposed at the fitting part of the steering post bracket 30, thereby improving the strength. On the other hand, the motor part 35a of a wiper unit 35 vibrates at the operating time of the wiper, but this vibration is transmitted to the wiper bracket 32 through an extended part 35. However, as the rigidity of this part is improved by the disposition of the wiper bracket 32, the vibration from a motor part 35d is also suppressed. Accordingly, the vibration of the whole air box main body 21 is suppressed so as to reduce vibration noise.

Furthermore, since the wiper unit is supported by the wiper bracket, vibrations from the wiper unit are suppressed, unlike the conventional wiper unit which is brought into direct contact with the bottom surface of the air box body.

[Example] Hereinafter, this invention will be explained based on examples.

FIG. 1 and FIG. 2 are diagrams showing one embodiment of the present invention.

First, to explain the structure, reference numeral 21 in the figure is an air box body disposed along the vehicle width direction between the engine room 22 @ and the passenger compartment 23 side, and the air box body 21 is open at the top. The air box body 21 has a cross-sectional structure, and a cross member 24 is joined to the air box body 21 along the vehicle width direction.

Specifically, the air box main body 21 includes a cowl top front 25 forming a vertical wall on the engine room side;
A dash upper 26 having a cross-sectional shape forming a bottom part and a wall part of the vehicle interior 11k11, and this dash upper 26
