Abstract:
A power transmission device includes a pulley 1 and a hub 2 having an inner hub 21, a rubber damper 22 and an outer hub 23. A hub side engagement portion 24 formed of an elastic material and arranged either one, or both, of inner peripheral surface and outer peripheral surface of the outer hub engages with a pulley side engagement portion 12, arranged at a position corresponding to the outer hub, of the pulley in concavo-convex fitting to thereby constitute a torque transmission structure between the hub and the pulley. The hub side engagement portion and the pulley side engagement portion have a concavo-convex outer shape and mesh with each other.
