Summary:To provide a motor which can be downsized in an axial direction.SOLUTION: A motor comprises a rotor, a stator, a circuit board 28, a stator housing part 25, a sealing member 26, and a lid part. The rotor rotates around a rotation axis. The stator faces the rotor with a gap provided inside in a radial direction. The circuit board is connected to the stator and is disposed on one side in an axial direction of the stator. The stator housing part houses the stator and the circuit board and has a cylindrical shape with an opening 25a on one end surface in the axial direction. The sealing member is filled in the stator housing part. The lid part covers the opening. One end in the axial direction of the stator housing part is located closer to the other side in the axial direction than the other end in the axial direction of the lid part located inner side in the radial direction than the stator housing part.SELECTED DRAWING: Figure 8 【課題】軸方向に小型化が可能なモータを提供する。【解決手段】モータは、ロータと、ステータと、回路基板２８と、ステータ収容部２５と、封止部材２６と、蓋部と、を備える。ロータは、回転軸を中心として回転する。ステータは、ロータと径方向内側に隙間を介して対向する。回路基板は、ステータに接続され、ステータの軸方向一方側に配置される。ステータ収容部は、ステータ及び回路基板を収容し、軸方向の一端面に開口部２５ａを有し、筒状に形成される。封止部材は、ステータ収容部内に充填される、蓋部は、開口部を覆う。ステータ収容部の軸方向一端は、ステータ収容部よりも径方向内側における前記蓋部の軸方向他端よりも軸方向他方側に位置する。【選択図】図８
