とする電磁クラツチ。 A rotor made of a magnetic material and rotationally driven by a driving means, a disc-shaped armature plate made of a magnetic material and provided opposite to the rotor, and an annular ring plate fixed to the armature plate; A hub whose center portion is connected to the driven shaft, an excitation coil which magnetically attracts the armature plate toward the rotor when energized, and an outer circumferential portion of the hub and an inner circumferential portion of the ring plate are coupled to each other. In an electromagnetic clutch made of resilient rubber that separates the rotor from the armature plate when the armature plate is in a state of The radius of curvature of the corner edge opposite to the side surface of the one member is set to 0. 5 mm or less, and weld the corner edge of the other member to the side surface of one member over the entire circumference by laser beam welding or electron beam welding to join the armature plate and the ring plate. An electromagnetic clutch characterized by being fixed.
