[Problems to be solved by the invention]

 Incidentally, in such a vehicle door mirror device, as shown in FIG. 4, a housing 10 accommodating a mirror main body 20 therein is attached to a vehicle door. The mirror main body 20 is provided with a predetermined gap (S) between the inner peripheral surface of the housing 10 and the outer peripheral portion of the mirror main body 20 to allow the mirror main body 20 to move. In such a configuration, when the vehicle travels, a traveling wind is generated around the vehicle door mirror device, particularly around the housing 10. Then, the traveling wind goes around the back side of the mirror body 20 and generates a vortex (V) based on the turbulent flow around the outer periphery of the mirror body 20 provided in the housing 10. The action of the vortex (V) causes the mirror body 20 to vibrate. As a result, the image reflected on the mirror surface of the mirror body 20 is shaken by the above-mentioned vibration, and there is a problem that the rear view by the door mirror is deteriorated. In order to solve such a problem, an attempt has been made to provide a vehicle door mirror device in which traveling wind does not enter the housing and generate eddies or the like around the outer periphery of the mirror body. This is the purpose (issue) of the present invention.
