Claims

[Claims for Utility Model Registration] (1) A wiper motor having an output shaft attached to a panel and rotatably supported by an output shaft support portion, the tip side of which protrudes from an opening drilled in the panel, and the output shaft support. and a sealing member made of an elastic material that is held in the wiper motor housing and seals the opening, a cylindrical body that connects the inside of the housing to the outside in a portion of the housing of the wiper motor near the output shaft support part. At the same time, an annular cap part that fits on the outer periphery of the cylindrical body is integrally provided on the bottom surface of the sealing member, and a housing is provided between the outer periphery of the cylindrical body and the inner periphery of the cap part. A breather device for a wiper motor for a vehicle, characterized in that an outside air introduction passage is formed to communicate the inside of the wiper motor with outside air. (2) Forming at least one or more grooves extending from the base to the tip of the cap part on the inner periphery of the cap part, creating a gap between the inner periphery of the cap part and the outer periphery of the cylindrical body. A breather device for a wiper motor for a vehicle according to claim 1, characterized in that at least the outside air introduction passage is formed. (3) At least two protrusions are integrally provided in the axial direction at appropriate intervals on the outer circumference of the cylindrical body, and a gap is provided between the outer periphery of the cylindrical body and the inner periphery of the cap portion. 2. A breather device for a wiper motor for a vehicle according to claim 1, wherein the outside air introduction passage is formed by causing the outside air to pass through.
