Claims

[Scope of Claim for Utility Model Registration] (1) A hub is mounted on one end of the rotating shaft horizontally mounted on the housing through the fastening of a stopper, and an armature disk is mounted on the hub in the axial direction through a plate spring. In the electromagnetic clutch, the hub and the armature are connected to the hub and the armature so that the hub and the armature can move forward and backward, while the housing side rotatably supports a pulley rotor facing the disk, and an electromagnetic coil is fixedly attached to the housing side facing the disk. Twisting of the rotating shaft in an electromagnetic clutch that connects disks with a certain amount of play between them and allows the armature disk and hub to rotate relative to each other over a certain angle through the play. Amplitude reduction structure. (2) The above-mentioned hub is divided into a fixed hub and a movable hub, and one of the hubs has a projection and the other hub has a recess facing each other, and the projection and the recess are formed so as to face each other. A structure for reducing the torsional amplitude of a rotary shaft in an electromagnetic clutch according to claim 1, wherein play is created by engagement with a certain clearance between them. (3) A protrusion is provided at the base of the plate spring, and a guide groove formed in an arc is formed on the hub and stopper at the connecting part of the plate spring, and the protrusion is inserted into the guide groove. A structure for reducing the torsion amplitude of a rotating shaft in an electromagnetic clutch according to claim 1, wherein play is created by engaging the clutch movably in the circumferential direction.
