A friction facing that is frictionally engaged with the front cover is provided between the turbine of the torque converter and the front cover so as to be slidable in the axial direction, and a plurality of longitudinal torsion springs are connected to the friction facing and the turbine in the circumferential direction. A retaining plate and a side plate are fixed to a piston facing the front cover and fixing a friction facing, in which the retaining plate and the side plate are connected to each other so as to be relatively rotatable through the piston, and torsion springs are provided on both the outer and inner circumferential parts. A holding part that holds the torsion spring on the outer periphery from the outside is formed in a continuous cylindrical shape over the entire circumference of the retaining plate, and a holding part that holds the torsion spring on the outer periphery from the inside is formed on the side plate. A retaining portion for retaining the torsion spring on the inner circumference is formed on the retaining plate and the side plate, and the driven plate is disposed along the end surface of the front cover side of the turbine, and the retaining portion for retaining the torsion spring on the inner circumference is formed on the turbine hub connected to the output shaft. A lock-up damper device for a torque converter characterized by connecting both torsion springs so as to be able to provide a buffer.
