Claims

[Scope of utility model registration request]

an input rotor, a bearing attached to the input rotor, an output rotor attached to the compressor so as to be rotatable with the input rotor, and an armature provided on the output rotor to face the input rotor. , and an electromagnetic coil that attracts this armature, and when a voltage is applied to this electromagnetic coil, the armature is attracted to the armature attraction surface provided on the input rotor side, and this armature rotates together with the input rotor. In the electromagnetic clutch, the rotating torque of the electromagnetic coil is transmitted to the output rotor, an air vent hole is provided in the bottom or one or both of the sides of the holding frame that accommodates the electromagnetic coil, and the holding frame is filled with resin. The electromagnetic clutch is characterized in that the resin that has entered the air vent hole is prevented from coming out inward of the holding frame.
