ッチ。[Claims for Utility Model Registration] 1. A rotationally driven clutch rotor rotatably supported via a radial bearing on a protrusion having a cylindrical outer surface provided on a fixed part, and a clutch rotor disposed opposite to the clutch rotor. an armature supported by the main shaft is included in a magnetic circuit of a ring-shaped excitation coil device that is fitted into the protrusion at intervals and fixed to the fixing part, and when the excitation coil is energized, the armature In the electromagnetic clutch that transmits rotational motion to the main shaft by attracting and joining the clutch rotor to the clutch rotor, the clutch rotor faces the outer circumferential surface and the inner circumferential surface of the excitation coil device, leaving a slight gap, respectively. A cylindrical magnetic reinforcing ring is tightly fitted on the inner diameter side of the clutch rotor and faces the outer circumferential surface of the protrusion with a slight gap, thereby establishing a connection between the clutch rotor and the protrusion. An electromagnetic clutch characterized by reducing magnetic resistance between the two. 2. The above-mentioned magnetic reinforcing ring axially contacts and rests on the outer peripheral side portion of the above-mentioned radial bearing, and is fixed by caulking the inner extending end of the latch rotor. The electromagnetic clutch described in Range 1.
