Therefore, the risk that water falls on the upper surface of the cover member 5 and comes into contact with the connector 4 can be reduced, and the water can be further dropped away from the connector 4. In this way, it is possible to construct a drainage path that hardly flows to the cover member 5 side that follows the connector 4 downward.
- the motor support member 313 is fixed in a state of being fitted into an opening formed on the lower surface of the casing 312.
- the structure in which the motor support member 313 is fixed to the casing 312 is not limited to this form.
- the outer peripheral wall 3132 has a structure in which the tip of the outer peripheral wall 3132 constitutes the upper surface, but the motor support member 313 is fixed to the casing 312 in such a form that the tip constitutes the lower surface. Also good.
- the fan 311 mounted on the blower is a centrifugal fan, but the blower included in the present disclosure is not limited to such a fan form.
- the resin parts such as the fan 311, the casing 312, and the motor support member 313 can be a resin molded product containing a predetermined amount of talc or glass fiber in order to improve the strength of each part.
