A lock-up device includes a clutch part and a damper part. The clutch part is disposed between a front cover and a turbine, and transmits or blocks torque. The damper part transmits torque from the clutch part to the turbine, and absorbs torsional vibration. The damper part includes input and output members, elastic members, and a support member. The input member is connected to the clutch part. The output member is connected to the turbine. The elastic members connect the input and output members. The support member has a connecting part, a regulating part, and a stopper part. The regulating part is provided such that the output member is interposed axially between the regulating part and part of the input member. The stopper part is configured to contact the output member and prohibit the input and output members from rotating relative to each other by a predetermined angle or more.

A damper device includes first and second rotary members, elastic members, and seat members. The first rotary member includes an annular chamber, and first engaging portions provided in the annular chamber. The second rotary member includes a second engaging portion. The elastic members are aligned in a circumferential direction in the annular chamber, and elastically couple the first and second rotary members in a rotational direction.
