Problems to be solved by the invention

However, if the technique disclosed in patent document 2 is simply applied to a door mirror in which a plurality of cover members are engaged with a housing main body, the restricting projections provided so as to project toward the housing main body side and project toward the housing main body side come into contact with the housing main body, respectively, which leads to an increase in size of the cover members and an increase in size and weight of the mirror housing.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a door mirror that can maintain the engagement state of a plurality of cover members with a housing main body while avoiding an increase in size and weight of a mirror housing.

Means for solving the problems

In order to achieve the above object, a door mirror according to the present invention is a door mirror including a mirror housing recess for housing a mirror, and a plurality of cover members covering the mirror housing from a side opposite to an opening direction of the mirror housing recess, the cover members engaged with each other being engaged with the mirror housing, wherein a first restriction protrusion protruding toward the mirror housing is provided on each of the cover members, the restriction protrusion restricting the cover member from being deflected toward a side close to the mirror housing, and a first restriction protrusion protruding on one of the cover members engaged with each other is formed shorter than a second restriction protrusion protruding on the other cover member and abutting against the mirror housing, the first limit projection and the second limit projection are arranged to overlap in the vertical direction, and an abutment surface that the distal end portion of the first limit projection approaches or abuts is formed on the second limit projection.

In addition to the first aspect, according to a second aspect of the present invention, a groove that closes the one end portion on the side of the housing body as the contact surface and opens the other end portion on the side opposite to the housing body is formed in a base end portion of the second restriction projection having a distal end portion that contacts the housing body, and the first restriction projection is fitted in the groove.

Effects of the invention

According to the first aspect of the present invention, the first regulating projection on the one cover member side is shorter than the second regulating projection on the other cover member side and is disposed so as to overlap the second regulating projection in the vertical direction, and the distal end portion of the first regulating projection is close to or brought into contact with the contact surface formed on the second regulating projection. Further, the first restriction projection is formed shorter than the second restriction projection, so that it is possible to suppress an increase in size and weight of the cover member having the first restriction projection, and further, to suppress an increase in size and weight of the mirror housing.

Further, according to the second aspect of the present invention, since the first regulating projection is fitted in the groove formed in the second regulating projection, the cover member on the side where the second regulating projection is provided can be made lighter, and the increase in weight of the mirror housing can be more effectively suppressed.
