A motor includes a stator core fitted to a cylindrical portion of a case, a rotor core being rotatable in the stator core, soft magnetic poles radially extending from the rotor core, and magnet poles disposed between the soft magnetic poles. The case includes a bottom portion having a ring-shaped plate portion, a protrusion portion, and a bearing-supporting portion extending from the protrusion portion. A condition that L2≧t and a condition that L1≧L2 are met, wherein t represents a thickness of the bottom portion, L1 represents a distance in an axial direction between a side surface of the ring-shaped plate portion close to the stator core and a protrusion end of the protrusion portion close to the rotor core, and L2 represents a distance in the axial direction between the side surface and an end surface of a bearing opposite to the rotor core.
