<p>PROBLEM TO BE SOLVED: To provide a structure, by which waterproof property is secured without adding a sealing agent or providing a complicated waterproof wall. SOLUTION: A grommet 16 is provided between an engaging part 13 of a motor 1 and a connector 2. An outer periphery side lip having a waterproof structure against water from the outside is formed on the grommet 16. An inner diameter side lip is also formed on the grommet 16 on the side of the fan motor 1 so as to prevent water flowing along the outer periphery of the mating face between a motor yoke 4 and an end housing 5 from coming into the motor 1. A groove 26 is formed between both lips formed on the grommet 16 to guide water along the groove 26 to the ground so that the water does not pool in the engaging part 13. Thus, the intrusion of water into the fan motor 1 is further reduced.</p> |
