摘要： An electromagnetic clutch is provided which produces sufficiently large clutch force by increasing the clutch capacity without increasing the number of inner and outer clutch plates. The electromagnetic clutch includes an intermediate member (8) that is connected to inner clutch plates (7a) so as not to be rotatable relative thereto and moves toward a clutch mechanism (7) under rotational force of a rotational member (5). The intermediate member (8) has: a pressing portion (23a) for pressing an armature (21) in the direction to frictionally couple the inner and outer clutch plates (7a, 7b) as the intermediate member (8) moves toward the clutch mechanism (7); and a movement force conversion section (24) for converting rotational force of a rotational member (6) into movement force toward the clutch mechanism (7). The movement force conversion section (24) is arranged between the intermediate member (8) and the rotational member (5).
