Abstract
A lock-up device includes a clutch disc, a piston, a temperature detection member and a gap adjustment mechanism. The clutch disc is disposed between a front cover and a turbine. The piston is disposed in opposition to the front cover through the clutch disc so as to be movable in an axial direction, and presses the clutch disc toward the front cover. The deformation amount of the temperature detection member is adjusted in accordance with surrounding temperatures. In accordance with the deformation amount, the gap adjustment mechanism adjusts a gap between the front cover and the piston to be a first gap at a first temperature. Further, in accordance the deformation amount, the gap adjustment mechanism adjusts the gap between the front cover and the piston to be a second gap narrower than the first gap at a second temperature higher than the first temperature.
