Abstract: A door mirror device for automobiles, wherein a mirror housing supporting a mirror is urgingly held by a coil spring to a mirror base fixed to a vehicle body. Their respective end portions which are held are provided with marginal portions which are closely attached to each other throughout their respective entire areas. On the inside of the respective marginal portions of the mirror housing and the mirror base, a plurality of projections extend into each other's inside portion in staggered fashion one above the other, so that when the mirror housing is tilted, the respective opposing projections are engaged with each other to prevent any vertical displacement of the mirror housing, and that when an applied external force is removed, the mirror housing returns to its initial position without a fail.
