ABSTRACT:
A lockup device7having a dual friction surface to make it possible to arrange a friction coupling part on the outside with respect to the radial direction is provided. The lockup device7has a clutch plate71, a drive plate72, a driven plate73, a plurality of torsion springs74, a spring holder80, a piston75, and a piston coupling mechanism76. The piston75radially extends to the position of a friction coupling part71cof the clutch plate71. The mounting radius of the torsion springs74is shorter than a radius extending to the radial position of the outer circumferential edge of the piston75or the friction coupling part71c. The protrusions72dof the drive plate72mate with the recessions71eof the clutch plate71at a radial position that is farther from the rotational axis than mounting radius of the torsion springs74.
