A lockup clutch in a hydrodynamic torque converter has an axially movable piston which can be pressed against a contact face of a flange of the converter housing in a switching position via at least one friction facing. At least one of the structural component parts of the flange of the converter housing or the piston serves as a carrier for a deformation element axially arranged between it and the other structural component part. The deformation element is connected with the carrier on at least one radial side and is in a working connection with the carrier at least at the other radial side via an elastic supporting device. The deformation element extends at least within the area of extension of the friction facing.
