To provide a motor including a lid cylinder part for fitting inner and outer peripheral surfaces, and capable of being molded by press working.SOLUTION: A motor 1 includes a rotor 20 having a shaft 21 placed along the central axis J extending in a vertical direction and rotating about the central axis, a stator 30 facing the rotor via a gap in a radial direction, a housing 40 having a cylindrical part 44 surrounding the stator from radial outside, and a lid member 10 located at an upper side of the stator, and covering an opening at the upper side of the stator. The lid member has a cylindrical lid cylinder part 18. The lid cylinder part has a first portion 15 to be fitted with an external device on the inner peripheral surface, and a second portion 17 fitted to the inner peripheral surface of the housing on the outer peripheral surface. The first and second portions are placed while deviating from each other in an axial direction.SELECTED DRAWING: Figure 1 【課題】内周面および外周面を嵌合させる蓋筒部を有するとともにプレス加工により成形可能な蓋部材を備えるモータの提供。【解決手段】モータ１は、上下方向に延びる中心軸Ｊに沿って配置されたシャフト２１を有し中心軸周りに回転するロータ２０と、ロータと径方向に隙間を介して対向するステータ３０と、ステータを径方向外側から囲む筒状部４４を有するハウジング４０と、ステータの上側に位置し、筒状部の上側の開口を覆う蓋部材１０と、を備える。蓋部材は、円筒状の蓋筒部１８を有する。蓋筒部は、内周面において外部装置が嵌る第１部分１５と、外周面においてハウジングの内周面に嵌る第２部分１７と、を有する。第１部分と第２部分とは、軸方向にずれて配置される。【選択図】図１
