Abstract

The present invention provides a housing structure of a door mirror in which a fixed-side housing portion is reliably crimped to a fixing-side housing portion on the surface side of a housing. In the housing structure of a door mirror, a boss portion and a contact piece are located on the deeper side than first and second butting portions located on the surface side, and a projection portion is located farther than a screwing portion in a positional relationship in the vertical direction (an arrow Y direction) with respect to a horizontal plane passing through the first butting portion. Therefore, when the boss portion (first mounting portion) of an upper housing (fixing-side housing portion) and the contact piece (second mounting portion) of a lamp assy (fixed-side housing portion) are fixed by a screw, a screw tightening force can be concentrated on the projection portion as shown by an arrow A, and this force can be made to act on the first and second butting portions as shown by an arrow B.

Claims

1. A housing structure of a door mirror for an automobile, in a door mirror for an automobile having a cup-shaped housing, the housing comprising:

a fixing-side housing portion in which a first butting portion located on the surface side and a first mounting portion located on the deeper side than the first butting portion are provided; and

a fixed-side housing portion in which a second butting portion located on the surface side and brought into contact with the first butting portion and a second mounting portion to be crimped to the first mounting portion by a screw are provided,

wherein

in the first mounting portion, a screwing portion into which the screw is screwed in a substantially horizontal direction is provided at a position spaced in the vertical direction from a horizontal plane passing through the first butting portion; and

the first mounting portion and the second mounting portion are crimped by the screw through a projection portion, and this projection portion is located farther than the screwing portion from the horizontal plane in the vertical direction.

2. The housing structure of a door mirror according to claim 1, wherein

the housing includes an upper housing located on the upper side, a lower housing located on the lower side, and a lamp assy located between the upper housing and lower housing;

and

the fixing-side housing portion is the lower housing and the fixed-side housing portion is the lamp assy.

3. The housing structure of a door mirror according to claim 1, wherein

the housing includes an upper housing located on the upper side, a lower housing located on the lower side, and a lamp assy located between the upper housing and lower housing;

and

the fixing-side housing portion is the upper housing and the fixed-side housing portion is the lamp assy.

4. The housing structure of a door mirror according to claim 1, wherein

a projection portion is formed on either one of the first butting portion and the second butting portion.
