The motor includes a first rotation member and a second rotation member. The first rotation member has a predetermined rotation axis. The second rotation member includes a plurality of electric magnets arranged around the rotation axis. The motor is configured to energize the electric magnets of the second rotation member so as to cause relative rotation of the first rotation member to the second rotation member. The motor further includes a deformation suppressing part. The electric magnet includes a coil, a core, and an extension part. The coil in the form of a cylindrical shape is configured to extend along a protrusion direction across the rotation axis. The core in the form of a bar shape is configured to penetrate the coil in the protrusion direction. The extension part is made of a magnetic material. The extension part is configured to extend along the rotation axis from an end of the core close to the first rotation member. The deformation suppressing part is configured to suppress deformation of the extension part. |
