A door mirror device includes a mirror housing mounted to a mirror base, a folding mechanism for enabling the mirror housing to pivot rearward of the vehicle when a load higher than a predetermined value is applied to the mirror housing from the front side of the vehicle. The mirror housing has a first region occupying more than half of the vertical area of the mirror housing and has a second region occupying a less area than the first region. The outer surface of the second region is located in front of the outer surface of the first region. The acute angle in a plan view between the outer surface of the second region and an outer side surface of the vehicle is greater than the acute angle between the outer surface of the first region and the outer side surface of the vehicle.
