MOTOR

To provide a motor, having a connector in a lateral direction, capable of reducing a size of the motor, waterproofing a joint between a housing and a cover.SOLUTION: A motor 1 includes a motor body 50; a housing 20; a heat sink 25a; a controller 80 positioned on an upper side of the heat sink; a connector 90 connected to the controller; and a cover 60 surrounding the controller and the connector from an outer side in a radial direction. The heat sink includes a connector holder that has an open outer side in the radial direction. The motor includes an annular cover joint 100 that extends once along a surface of the heat sink and a surface of the connector in a peripheral direction and that surrounds the controller. The cover joint includes a stepped portion that includes a first surface and a second surface. The first surface faces the radial direction, and the second surface extends in the radial direction from a lower end of the first surface. The cover includes a cylindrical portion 62 that faces the first surface in the radial direction. The motor includes a waterproof material that seals a portion between the cylindrical portion and the first surface or a portion between the cylindrical portion and the second surface.SELECTED DRAWING: Figure 1 【課題】側方にコネクタを有するモータにおいてハウジングとカバーとの接合部を防水しつつ、小型化できるモータを提供する。【解決手段】モータ１はモータ本体５０と、ハウジング２０と、ヒートシンク２５ａと、ヒートシンク上に位置する制御部８０と、制御部に接続されるコネクタ９０と、制御部およびコネクタを径方向外側から囲むカバー６０と、を備える。ヒートシンクは、径方向外側に向かって開口するコネクタ保持部を有する。ヒートシンクおよびコネクタの表面を周方向に沿って一周し、制御部を囲む環状のカバー接合部１００を有する。カバー接合部は、径方向を向く第１面と、第１面の下端から径方向に広がる第２面とからなる段差部を有する。カバーは、第１面と径方向に対向する筒部６２を有する。筒部と第１面との間、または筒部と第２面との間を封止する防水部材を有する。【選択図】図１
