To provide a power transmission device capable of preventing intermittent operation characteristics of a first intermittent operation part from being adversely affected and preventing the first intermittent operation part from being affected by drag torque at a second intermittent operation part.
This power transmission device 1 is provided with: the first intermittent operation part 15 composed of an outer side rotary member 3, an inner side rotary member 5, and a plurality of clutch plates 11, 13; an intermittent operation part 21 having an annular pressing member 19 forming a pressing part 17 for pressing the first intermittent operation part 15; the second intermittent operation part 23 for operating the intermittent operation part 21; and an actuator 27 having an electromagnet 25 for operating the second intermittent operation part 23 intermittently. A recessed part 29 is formed on an inner peripheral side of the pressing part 17 of the pressing member 19, and an energizing member 31 for energizing the pressing member 19 in the direction for releasing connection of the first intermittent operation part 15 is arranged by facing a projection face in the axial direction of the clutch plates 11, 13 in the first intermittent operation part 15 in the recessed part 29.
