[Prior art]

 Vehicle rearview mirrors such as door mirrors generally include a mirror housing having an opening on the front surface and a mirror arranged at the front opening of the mirror housing. Recently, the mirror housing in the rear-view mirror for a vehicle is divided into two parts, a housing body and a garnish, and a cover-shaped garnish is attached to the rear part of the housing body so as to cover it from the outside. The two-part assembly structure type is often used. In such a mirror housing, the housing body and the garnish can be made of different materials or different colors, or different surface treatments can be applied. The mirror housing of such a rearview mirror for a vehicle generally engages the engaging claws provided on the housing body and the garnish with each other, and screws a screw from the inside (front surface side) of the housing body to the garnish side. The housing body and the garnish are assembled together. The screws are used in this mirror housing because it is not enough to assemble the housing body and garnish simply by engaging the housing body side engagement claw and the garnish side engagement claw with each other. This is because there is a risk that the assembly of the two will be disengaged, and this is intended to eliminate that risk. In addition, screwing the screw from the inside of the housing body to the garnish side is not desirable because it is visible from the outer surface of the garnish when the screw is screwed from the garnish side to the main body of the housing. The purpose is to improve the appearance. As the mirror housing of the above-mentioned vehicle rearview mirror, there is, for example, the one described in Japanese Utility Model Laid-Open No. 62-8846.

[Problems to be solved by the device]

 However, the above-mentioned conventional mirror housing of a rear-view mirror for a vehicle is not sufficiently assembled with the housing body and the garnish due to the mutual engagement between the housing body-side engagement claw and the garnish-side engagement claw. To compensate for this, it is necessary to screw the screw from the inside of the housing body to the garnish side. For this reason, it is impossible to attach a mirror or the like to the housing body side, to attach the housing body side to a vehicle body such as a door, and then to attach the garnish to the housing body, so-called post-assembly of the garnish.

An object of the present invention is to provide a mirror housing for a rear-view mirror for a vehicle, in which the housing main body and the garnish are firmly assembled and the garnish can be assembled afterward.
