A power transmission device has an interlocking membermoving a pressure memberfrom an inactive position to an active position. A release spring (m) applies an urging force, while allowing movements of the interlocking memberand the pressure member, until drive-side clutch platesand driven-side clutch platesreach an engaged state before the drive-side clutch platesand the driven-side clutch platesare pressed against each other. A clutch springis compressed in a process where the interlocking membermoves after the drive-side clutch platesand the driven-side clutch plateshave reached the engaged state. The clutch spring applying a press-contact force between the drive-side clutch platesand the driven-side clutch plateswhile allowing movements of the interlocking memberand the pressure member. The set load of the clutch springis set to be smaller than the maximum load of the release spring (m).
