发明名称 Washer pump apparatus
摘要 A washer pump apparatus is provided which has a simple structure and a small number of parts, which can be manufactured easily and at a low-cost, and in which a breathing hole, which communicates an interior of a motor portion of a washer pump with the atmosphere, is made sufficiently waterproof. In the washer pump apparatus, an inlet of the washer pump is mounted to a washer tank via a grommet. A vent groove, which communicates with the breathing hole of the motor portion, is formed at the grommet, and a vent hole is formed between the vent groove and the washer tank. Accordingly, satisfactory waterproofing is ensured, and the interior of the motor portion is open to the atmosphere. Because of a simple structure of forming the vent hole at the grommet, another part such as a waterproofing cover or the like is not needed, and a number of parts used does not increase. The washer pump apparatus can be manufactured easily and inexpensively.
