PROBLEM TO BE SOLVED: To provide a mounting structure for a rotary member, in which an impeller will not come off a rotary shaft even when force is added to the impeller during operation. SOLUTION: A bracket 20 is fixed to a boss 18 in a cylindrical form to cover the opposite side of a motor at the boss 18, and a through hole 32 is formed through the boss 18 at a center part of it in such a way that the rotary shaft 14 freely rotates. A stopper 16 is fixed to be perpendicular to the rotary shaft 14. A projection 30 is projected on an inner circumferential part of the boss 18 in such a way that the stopper 16 is applied to it. A holding hole 40 for holding a tip part of the rotary shaft 14 is formed at a center part of the bracket 20. COPYRIGHT: (C)2006,JPO&NCIPI
