A brushless motor is provided with a stator (11) which forms a rotating magnetic field, a rotor (12) which is rotated by the rotating magnetic field, a motor case (13) to which the stator (11) is mounted, a bracket (16) which is disposed between the motor case (13) and a gear box (15), and a resolver (21) which detects the rotational angle of the rotor (12). The brushless motor also comprises a first bearing (14) and a second bearing (20), which support the rotor (12) in a rotatable manner. The first bearing (14) and the second bearing (20) are arranged at different positions in the direction along the axis (A) about which the rotor (12) rotates. The second bearing (20) is disposed further toward the inside of the gear box (15) in the direction along the axis (A) than the position at which the bracket (16) is mounted to the gear box (15). As a result of the configuration, moment generated when the rotor (12) vibrates can be reduced. |
