Abstract
[Problem] To provide a rotor unit that may effectively prevent detachment of a magnet with a holder while absorbing dimensional errors of a rotor main body and the magnet. [Solution] In the rotor unit according to the present invention, the holder mountable on the rotor main body prevents the magnet from being detached from the rotor main body. The holder includes an elastically deformable insertion arm extending from a flat-plate like holder main body, a hook portion provided on a free end side of the insertion arm, an elastically deformable magnet pressing arm extending from the holder main body, and a magnet pressing portion provided on a free end side of the magnet pressing arm. The rotor main body includes a hook hole into which the insertion arm is inserted, and the hook hole is provided with a locking portion in which the hook portion is lockable. When the hook portion is locked in the locking portion, the magnet pressing portion presses an end face of the magnet due to inherent elasticity of the magnet pressing arm accompanying elastic deformation.
