Claim Text:
1. An electromagnetic clutch for intermittently transmitting power of a drive source to a driven device, the electromagnetic clutch comprising: a rotor rotated by the power of the drive source; an armature facing the rotor, and connected to a rotary shaft of the driven device; and an electromagnetic coil unit having an electromagnetic coil, and for causing, when power is supplied to the electromagnetic coil, the rotor and the armature to magnetically adhere to each other to enable the transmission of the power from the drive source to the driven device, wherein the electromagnetic coil unit includes: a bobbin having a connector mounting portion, and around which the electromagnetic coil is wound; a power supply connector attached to the connector mounting portion, to supply external power to the electromagnetic coil; and a field core having a storage portion in which a through hole is formed, a proximal part of the power supply connector and the bobbin being stored in the storage portion in a state in which a distal part of the power supply connector is exposed to the outside from the through hole, and the storage portion being filled with resin, wherein the power supply connector supplies the external power to the electromagnetic coil by being connected to a power connector, and the distal part of the power supply connector protrudes from the through hole, substantially in parallel with an axial direction of the field core.
