Abstract
A first friction plate is disposed between a first rotor and a second rotor in an axial direction. The first friction plate includes an outer slide portion and an inner slide portion. The outer slide portion is disposed radially outside an elastic member. The outer slide portion generates a friction force when rotated relative to the second rotor. The inner slide portion is disposed radially inside the elastic member. The inner slide portion generates a friction force when rotated relative to the first rotor. This structure stably generates a friction force.
Claims20
A power transmission device comprising:
- a first rotor;
- a second rotor disposed to be rotatable relative to the first rotor;
- an elastic member elastically coupling the first rotor and the second rotor therethrough to each other;
- and
- a first friction plate disposed between the first rotor and the second rotor in an axial direction, wherein
- the first friction plate includes
- an outer slide portion disposed radially outside the elastic member, the outer slide portion generating a friction force when rotated relative to the second rotor, and
- an inner slide portion disposed radially inside the elastic member, the inner slide portion generating a friction force when rotated relative to the first rotor.
