To provide a damper capable of coping with large variation torque by a plurality of power sources without increasing dimensions and weight.

The damper 30 for a hybrid drive device performs transmission while suppressing the variation torque produced by an engine 10 and an electric motor 20. The damper 30 for the hybrid drive device has a limiter mechanism 35 blocking the transmission of power when the variation torque by the engine 10 and the electric motor 20 reaches a predetermined value.
