Abstract
A power transmission device includes a first rotor, a second rotor, a support member, an elastic member, and a first friction plate. The second rotor is disposed to be rotatable relative to the first rotor. The support member is attached to the second rotor. The elastic member elastically couples the first rotor and the second rotor therethrough to each other. The first friction plate includes an outer slide portion and an inner slide portion. The outer slide portion is disposed radially outside the elastic member. The inner slide portion is disposed radially inside the elastic member. The inner slide portion is disposed between the second rotor and the support member in an axial direction. Each of the outer slide portion and the inner slide portion generates a friction force when the first friction plate is rotated relative to the second rotor.
