The damper portion includes an input member, an output member, a plurality of elastic members, and a support member. The input member is connected to the clutch portion. The output member is relatively rotatable to the input member, and connected to the turbine. The elastic members elastically connect the input member and the output member in a rotating direction. The support member has a connecting portion and a plurality of supporting portions. The connecting portion is connected to the input member. The plurality of supporting portions can support inner peripheral surfaces of the plurality of elastic members.SELECTED DRAWING: Figure 4
