Lock-up device

A lock-up device for a torque converter configured to transmit a torque from a front cover to a transmission-side member through a turbine of the torque converter, the lock-up device comprising:

• a clutch part disposed between the front cover and the turbine, the clutch part configured to transmit or block the torque;
• and
• a damper part configured to transmit the torque from the clutch part to the turbine, the damper part configured to absorb and damp torsional vibration,
• the damper part including
• an input member connected to the clutch part,
• an output member rotatable relative to the input member, the output member connected to the turbine,
• a plurality of elastic members accommodated in the input member, the plurality of elastic members configured to elastically connect the input member and the output member in a rotational direction, and
• a support member, the support member having
• a connecting part connected to the input member,
• a plurality of support parts configured to support radially inner surfaces of the plurality of elastic members, and
• a stopper part configured to contact the output member, the stopper part further configured to prohibit the input member and the output member from rotating relative to each other by a predetermined angle,
• the stopper part being disposed radially inside of the connecting part.
