Abstract
A power transmission device has a back torque transmission cam that brings driving clutch platesand driven clutch platesinto press contact with each other. This occurs by moving a second clutch memberwhen a rotational force is input to a first clutch member, via the output shaft. A pressure memberis located at a non-actuation position. A back torque transmission cam can hold abutment between an interlocking memberand weight memberby moving the second clutch memberin a direction of being brought into proximity to the interlocking member
