<p><P>PROBLEM TO BE SOLVED: To provide a motor which improves waterproof performance and economic efficiency. <P>SOLUTION: In order to solve the problem, the motor M includes: a cylindrical stator 2 wound with a winding 1; a case 3 for accommodating the stator 2 at its internal peripheral side; and a molding resin 4 which is injected into the case 3, and covers the winding 1. The motor is also characterized in that the case 3 is formed into a bottomed cylindrical shape, and a clearance 7a functioning as gas drainage at molding is formed between a cylinder of the case 3 and the stator 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
