[Problem] To provide an electromagnetic clutch that suitably manages the relative distance between a bimetal and a bridging lead wire part in the axial direction of the electromagnetic clutch and that increases the reliability of an electric current cutoff device. [Solution] A magnetic clutch configured such that: a bobbin (41) around which is wound an electromagnetic coil (42) that causes a rotor and an armature to magnetically adhere is provided with an inner wall (41d) and an outer wall (41e) that face each other and extend in the direction of a bimetal, and with an inside contact part (41f) and an outside contact part (41g) that extend from respective extension-side end parts of the inner wall (41d) and the outer wall (41e) in the directions of inner peripheral and outer peripheral opening-end edges of a ring case (43) that houses the bobbin (41); the inside contact part (41f) and the outside contact part (41g) come into contact with the inner and outer opening-end edges of the ring case (43); the bobbin (41) is positioned and housed within the ring case (43); and a bridging lead wire part (52) bridges positions on the inner wall (41d) and the outer wall (41e) that are at the same height. |
