Description

  The present invention relates to a mirror base cover structure of a vehicle.

  Patent Document 1 describes an attachment structure of an outside mirror including an upper mirror stay, a lower mirror stay, and a stay drive motor for rotating these, and the lower end of the lower mirror stay and the motor are covered with a cover. .

Japanese Utility Model Application Publication 6-72748

  A mirror base portion fixed to the vehicle body side and supporting a base shaft extending in the vertical direction of the mirror stay is a high rigid and hard portion, and such a mirror base portion is a cab like the structure described in Patent Document 1 If provided so as to project forward from the front, a pedestrian may collide against the mirror base and receive a strong impact, for example, in a vehicle collision.

  In addition, it is also possible to relieve the impact which a pedestrian receives by setting the gap | interval of the front-back direction from the front end of a mirror base part to a cover large. However, in this case, the projection amount of the mirror cover from the front of the cab increases and the overall length of the vehicle also increases, so it is difficult to reduce the impact of the pedestrian in a vehicle whose overall length is limited.

  Then, this invention aims at provision of the mirror base cover structure which can reduce the impact which a pedestrian receives when colliding with a pedestrian, controlling increase of the full length of vehicles.

  In order to achieve the above object, the present invention is a mirror base cover structure of a vehicle in which a front cover panel of a cab covers a front surface of a cab and a door closes a side of the cab openably and closably. And a side cover panel.

  The mirror base portion is disposed rearward of the upper end of the cab front cover panel in the vehicle width direction and outside the vehicle width direction, and is disposed forward of the front end of the outside surface of the door and inward of the vehicle width direction and fixed to the vehicle body And supports a base shaft extending in the vertical direction of the mirror stay. The cab side cover panel has a mirror base cover vertical surface that covers the mirror base from the front and the outside in the vehicle width direction, is disposed at a cab corner between the cab front cover panel and the door, and is fixed to the vehicle body. The mirror base cover longitudinal surface portion is provided with a front side region spaced apart from the mirror base portion obliquely inward in the vehicle width direction to a front side region, and a rear side region extending obliquely from the front side region to the vehicle width direction outside in the rear direction. The rear region of the mirror base cover longitudinal surface may be continuous with the front end of the outer surface of the door.

  In the above configuration, the front region of the mirror base cover longitudinal surface portion is spaced apart from the mirror base portion to the front inward in the vehicle width direction, and the rear region extends from the front region to the outside in the vehicle width direction.

  Therefore, when a pedestrian or the like collides with the cab side cover panel from the front and the collision position is the front area of the mirror base cover vertical surface, the impact is absorbed by the gap between the front area and the mirror base. It is possible to reduce the impact that a pedestrian or the like receives. On the other hand, when the collision position is the rear area of the mirror base cover vertical surface, the pedestrian etc. is guided to the outside in the vehicle width direction along the inclination of the rear area, so the pedestrian etc. and the mirror base Collision with the vehicle can be avoided or reduced.

  In addition, since the mirror base portion is disposed rearward of the upper end of the cab front cover panel in the vehicle width direction and on the inner side of the front end of the outer surface of the door in the vehicle width direction, It is possible to reduce the impact received by a pedestrian or the like while suppressing an increase in (full length of the vehicle) and an increase in length in the vehicle width direction (full width of the vehicle).

  According to the present invention, it is possible to reduce the impact which the pedestrian receives when colliding with the pedestrian by the mirror base cover vertical surface portion while suppressing the increase in the overall length of the vehicle.
