Abstract: A torque converter includes a lock-up device that directly connects a torque converter cover that rotates together with a pump impeller to a turbine runner connected to an output axis. The lock-up device includes a damper spring in a clutch piston that contacts with or moves away from the torque converter cover. In addition, an intermediate member is provided inside the damper spring. A center part of the damper spring is projected toward the inner side of the clutch piston in the radial direction by damper pressing portions and fixed to both ends of the damper spring and a connecting member and pushed onto the projecting part of the intermediate member.
