PROBLEM TO BE SOLVED: To provide a motor capable of suppressing occurrence of a strange sound while suppressing an increase in processing man hours.SOLUTION: A motor 10 comprises: a yoke 14 having a bearing housing part 14d; a first ball bearing 18 housed in the bearing housing part 14d, and that supports a rotary shaft 17 of a rotor 12 rotatably; and a cylindrical sleeve 19 that is interposed between an outer peripheral surface of the first ball bearing 18 and the bearing housing part 14d, and that has elasticity. The sleeve 19 covers the axial whole outer peripheral surface of the first ball bearing 18, and each of axial both end parts of the sleeve 19 extends to the outside from axial both end surfaces of the first ball bearing 18.SELECTED DRAWING: Figure 1 【課題】加工工数の増加を抑えつつ、異音の発生を抑制できるモータを提供する。【解決手段】モータ１０は、軸受収容部１４ｄを有するヨーク１４と、軸受収容部１４ｄに収容され、ロータ１２の回転軸１７を回転可能に支持する第１ボールベアリング１８と、第１ボールベアリング１８の外周面と軸受収容部１４ｄとの間に介在された弾性を有する筒状のスリーブ１９とを備える。そして、スリーブ１９は、第１ボールベアリング１８の外周面の軸方向全体を覆い、該スリーブ１９の軸方向両端部の各々が第１ボールベアリング１８の軸方向両端面よりも外側まで延出されている。【選択図】図１
