PROBLEM TO BE SOLVED: To provide an inexpensive motor by making it difficult for lubricant in a bearing to leak out. SOLUTION: This motor 1 is equipped with a housing 2 which has a tubular part and a seat provided at the internal perimeter of the tubular part; a cylindrical bearing 3 which is engaged with the internal perimeter of the tubular part; a rotating shaft 4 which is held rotatably via lubricant within the bearing; a rotor 5 which is provided at the top of the rotating shaft; and a cap 7 which is charged in circular space surrounded by the internal perimeter of the above tubular part, the topside of the bearing, and the periphery of the rotating shaft. Herein, the cap 7 has an engaging part 7a which engages elastically with the above cylindrical part, a cover 7b which covers the topside of the above bearing, and a press 7f which presses the topside of the above bearing. The above bearing is supported with the seat of the above housing and the press 7f of the cap. COPYRIGHT: (C)2005,JPO&NCIPI
