Claims

[Claims for Utility Model Registration] A rotor that rotates when driven by a drive source, an armature that faces the rotor at a predetermined distance, an excitation coil that attracts the armature to the rotor, and rotation of the armature. an electromagnetic clutch comprising: a hub for transmitting a signal to a rotating shaft via a buffer member; A plurality of second engagement grooves extend radially on the side surface at a predetermined angle from the first engagement groove, and a non-engagement groove extends radially between each adjacent first engagement groove and each second engagement groove. the armature has a plurality of radially extending first engagement protrusions that engage with the first engagement groove on a surface that abuts the one side surface of the buffer member, and the hub has an annular shape with a groove; An electromagnetic clutch comprising a plurality of second engagement protrusions that engage with the second engagement groove on a surface that abuts the other side surface of the buffer member.
