VEHICULAR DOOR MIRROR DEVICE

A vehicular door mirror device is provided which includes an engagement claw provided on one of a lamp unit and a mirror housing being engaged with a latching part provided on the other of the lamp unit and the mirror housing, wherein the mirror housing includes a housing main body that has a mirror housing recess part and is pivotably supported by a base member, and a cover that has the slit formed therein and is mounted on the housing main body so as to cover the housing main body from a side opposite to an open direction of the mirror housing recess part, the cover being provided with a restriction part that restricts displacement of the engagement claw toward a direction in which the engagement claw disengages from the latching part. The lamp unit is thus prevented from detaching from the mirror housing even under an external impact.
