Summary: | To provide a motor in which no particles generated when a positioning portion and an internal wall of a connector cover rub against each other enter inside the motor when the positioning portion of a cover member is fitted inside the internal wall of the connector cover.SOLUTION: A motor 1 includes a motor body 50 including a rotor 30 and a stator 40 centering on a central axis J extending in an up-and-down direction; a housing 20 that houses the motor body 50; a controller 80 positioned above the motor body 50 and controlling a rotation of the rotor 30; and a cover 60 surrounding the controller 80 from an outer side in a radial direction. The housing 20 includes an annular cover joint 100 surrounding the controller 80 viewed in an axial direction. The cover 60 includes a cylindrical portion 62 surrounding the cover joint 100 from the radial direction. The cover joint 100 includes a contacting portion radially in contact with a front side surface of the cylindrical portion 62, and an adhesive joint radially bonded to the cylindrical portion 62 via an adhesive.SELECTED DRAWING: Figure 1
【課題】カバー部材の位置決め部をコネクタカバーの内壁部の内側に嵌合させる場合、位置決め部とコネクタカバーの内壁部とが擦れ合う際に発生するパーティクルが内部に入り込まないモータを提供する。【解決手段】上下方向に延びる中心軸Jを中心とするロータ30およびステータ40を備えるモータ本体50と、モータ本体50を収容するハウジング20と、モータ本体50の上側に位置しロータ30の回転を制御する制御部80と、制御部80を径方向外側から囲むカバー60と、を備えるモータ1。ハウジング20は、軸方向に見て制御部80を囲む環状のカバー接合部100を有する。カバー60は、カバー接合部100を径方向から囲む筒部62を有し、カバー接合部100は、筒部62の表面と径方向に接触する接触部と、接着剤を介して筒部62と径方向に接着される接着接合部と、を有する。【選択図】図1 |
