Abstract
A lock-up device includes a clutch part and a damper mechanism. The damper mechanism includes an input plate, an output plate, a plurality of torsion springs, an intermediate member and a restriction member. The intermediate member is configured to cause at least two of the torsion springs to act in series. The restriction member is fixed to a clutch output member of the clutch part, while being disposed such that a part of the intermediate member is interposed between the input plate and the restriction member in an axial direction. The intermediate member is restricted from moving in a radial direction by the clutch output member, while being restricted from moving in the axial direction by the input plate and the restriction member.
