Claims

[Scope of utility model registration request]

a first rotating member, a field core disposed on one end surface side of the first rotating member and containing an electromagnetic coil;
a plate-shaped armature that faces the other end surface of the rotating member and is arranged so as to be able to approach and separate from the first rotating member; and a plate-shaped armature that is arranged on the outer end surface of the armature and is integrally formed with the second rotating member. a plate-shaped flange portion, one end of which is pivotally connected to the armature, and the other end of which is pivotally connected to the flange portion, and the pivoting portion with the armature is located at a greater radial distance from the center than the pivoting portion with the flange portion; An arc-shaped elastic member that constitutes a plurality of first dampers whose pivot joint with the armature is placed in a position that precedes the pivot joint with the flange in the direction of rotation of the armature, and which always urges the armature toward the flange. striations and
A predetermined gap is provided between the plurality of second dampers, each of which has a plurality of second dampers formed by concentrically supporting an elastic body embedded in a cylindrical damper case on a damper shaft installed upright on an armature. It consists of a stopper part formed opposite to a flange part,
When the transmitted torque from the first rotating member to the second rotating member is within a predetermined value, the torque is transmitted via the first damper, and when the transmitted torque exceeds the predetermined value, the torque is transmitted via the second damper. An electromagnetic clutch characterized by being designed to be
