[Problem] To provide a power transmission device which can inhibit the rotation of a pressure member relative to a clutch member, thereby inhibiting vibration in the same direction. [Solution] A power transmission device has: a clutch housing member (2) to which a plurality of drive-side clutch plates (6) are attached; a clutch member (4) to which a plurality of driven-side clutch plates (7) are attached; and a pressure member (5) which is capable of applying and releasing, in accordance with the movement of the clutch member (4) in the axial direction, a pressing force which causes the drive-side clutch plates (6) and the driven-side clutch plates (7) to engage with each other. By applying and releasing a pressing force which causes the drive-side clutch plates (6) and the driven-side clutch plates (7) to engage with each other, the power transmission device can transmit to a shaft (3), and intercept, rotary force inputted into the clutch housing member (2). The power transmission device is provided with a resistance member (11) which generates sliding resistance with respect to the pressure member (5) when the pressure member (5) rotates relative to the clutch member (4). |
