| description | [Object] To provide an electric motor that can be downsized in a rotation axis direction and can also suppress the deformation of a bearing and a bearing house portion along with the deformation of a resin shell.[Solving Means] An electric motor according to an aspect of the present invention includes: a columnar rotor; a shaft disposed along a rotation axis of the rotor; a cylindrical stator core disposed on an outer circumferential side of the rotor; a resin shell that covers the stator core; a bearing that rotatably supports the shaft; and a bearing house portion that stores the bearing. The resin shell includes an annular portion integral with the stator core, and an end surface portion connected to an end portion of the annular portion and expanding from the annular portion to an inner circumferential side. The end surface portion includes a connection portion to be connected to the bearing house portion. The bearing house portion includes a tubular portion and a flange portion extending from an end of the tubular portion to the outer circumferential side in the radial direction. An outer circumferential edge portion of the flange portion is fixed to the connection portion of the resin shell. |
