摘要： A motor device includes a motor housing, a coil portion, and a coil protection portion. The motor housing includes a housing main body and a displacement restriction portion. The displacement restriction portion extends from the housing main body toward a radially inner side to enter between two coil bodies adjacent to each other in a circumferential direction. The coil protection portion includes a protection outer peripheral portion. The protection outer peripheral portion is provided between the coil body and the displacement restriction portion. The protection outer peripheral portion extends along a displacement restriction surface in the circumferential direction and an axial direction. The displacement restriction portion is in a state of being caught by the coil body via the protection outer peripheral portion, thereby forming displacement of the coil body.

摘要： A motor device includes a motor housing, a stator, and a rotor. An axial gap is formed between the stator and the rotor. An internal space of the motor housing includes a stator region, an opposite region, and an outer peripheral region. In the axial gap, a gap outer peripheral end communicates with the opposite region through the outer peripheral region. A holder adjustment hole, a holder center hole, and the like are formed in the rotor. In the axial gap, a gap inner peripheral end communicates with the opposite region through the holder adjustment hole, the holder center hole, and the like.
