A torque converter is provided with a lockup device that functions as a clutch and as an elastic coupling mechanism. In one embodiment, the lockup device is configured to eliminate an outer cylindrical portion from its piston. Preferably, a spring holder has an outer portion arranged radially outside the torsion springs, while a drive plate has a cylindrical portion restricting radial movement of the spring holder. In other embodiments, the elastic coupling mechanism is configured with a sufficient number of sets of elastic members that act together in the rotational direction as if they were arranged end to end. The elastic coupling mechanism has one set of springs disposed radially inward of another set of springs. A spring holder connects first and second sets of springs such that the first and second sets of springs act together in the rotational direction as if they were arranged end to end.
