<p>PROBLEM TO BE SOLVED: To provide an axial flow fan of high durability, which prevents infiltration of liquid from a boundary part, when a sleeve for a bearing is formed as a different component in advance and then made a stator unit by molding the sleeve in a unified body, together with a stator core, a stator winding, electric circuit components, etc., after assembling, and when the fan is used under adverse environment. SOLUTION: An elastic member for maintaining closing properties is interposed between adjacent surfaces of a stator unit and a fan casing, thereby preventing infiltration of liquid to the inside.</p> |
