PROBLEM TO BE SOLVED: To provide a power transmission device capable of improving operability in clutch operation by surely avoiding momentary reciprocating motion of a pressure member when a cam for a back torque limiter acts. SOLUTION: The device includes a moving member 15 (a breaking means) which can force the other end of a specific biasing means (a clutch spring Sb) of a plurality of biasing means (clutch springs Sa, Sb) to be spaced from a pressure member 5 and breaks biasing force imparted to the pressure member 5 from the specific biasing means (clutch spring Sb) when an intermediate member 10 moves to the pressure member 5 through the action by a cam for a back torque limiter.
