Mirror device for vehicle

A mirror device for a vehicle, capable of preventing entrance of water into a motor case, and capable of ensuring smooth and appropriate rotation of the motor case even if a soft material is used for a cover. A supporting cylinder formed at a bottom wall portion of the motor case is rotatably supported at a lower end side of a shaft. A cylindrical member is formed continuously from a motor base having the same rigidity as the motor case. An upper end portion of the shaft is covered with the cylindrical member, which is rotatably supported by the shaft. The motor case and the motor base are interlocked, so they are rotatably supported together on the upper and lower ends of the shaft, and smooth rotation of the motor case can be ensured. Entrance of water between the shaft and the cover is prevented by the cylindrical member.
