<p>This electromagnetic clutch is provided with: a rotor (1) in which an electromagnetic coil (16) is embedded; and an armature (2) that is disposed facing the rotor (1) and that is adhered to the rotor (1) by means of the magnetic force of the electromagnetic coil (16). By means of the magnetic excitation of the electromagnetic coil (16), when the rotor (1) and the armature (2) are not in contact, a magnetic circuit (M1) is formed from the rotor (1) through a first armature plate (21), an intermediate layer (22), a second armature plate (23), the intermediate layer (22), the first armature plate (21), and returning to the rotor (1). When rotor (1) and the armature (2) are in contact, a magnetic circuit (M2) is formed from the rotor (1) through the first armature plate (21), a portion (13a) between slits (14) neighboring the rotor (1), the first armature plate (21), and returning to the rotor (1).</p> |
