PROBLEM TO BE SOLVED: To provide a motor capable of easily attaching a magnet hook member and reducing a vibration noise caused by the rotation of a rotor. SOLUTION: The motor M includes: a rotor 3 integrally provided on a rotary shaft 2; a stator 4 provided coaxially with the rotor 3; a plurality of permanent magnets 8 each housed in a plurality of magnet housing holes 32 piercing through the rotor 3 in a shaft direction; and first and second magnet hook plates (magnet hook members) 71, 72 each fixed on both end surfaces 3a, 3b of the rotor 3 to prevent the permanent magnets 8 from coming off from the permanent magnet housing holes 32. The first and second magnet hook plates 71, 72 have elastic pieces 75 inserted into the magnet housing holes 32 in a shrunk state and released in the magnet housing holes 32 to abut on the permanent magnets 8.
