    摘要: An electromagnetic actuator includes; a coil for excitation; a stator excited with different magnetic poles by energization of the coil; a rotor magnetized with different magnetic poles in a circumferential direction thereof, and rotated by a magnetic force generated between the rotor and the stator; and an outputting member rotated in conjunction with the rotor and outputting rotational movement of the rotor to a first blade and a second blade. The rotor and the outputting member are jointed by welding and a welding portion of the rotor lies in a boundary of the magnetic poles thereof.
