A power transmission device includes a power input member (1, 11) that rotates when torque is applied thereto, a power output member (21) that puts out the torque, and a transmitting member (31) that transmits the torque of the power input member to the power output member. The power input member and the power output member have substantially the same axis of rotation. The power transmission device has twisting characteristics with which the magnitude of the torque generated from the power output member continuously changes along a curve, with respect to a relative angle of twist between the power input member and the power output member. |
