Abstract
A windshield wiper motor having a motor casing and a reduction gear casing is provided with a crooked air passage between the casings which is provided with a breather hole at a position that neither coincides nor overlaps with a projection of the respective openings of the passage into the gear casing and motor casing, so that it is possible to perform a breathing action even if lubricating oil penetrates into the air passage through the opening since the oil will be prevented from entering and clogging the breather hole.
