付流体式動力伝達装置。 Equipped with a lock-up clutch placed between the front cover on the input side and the turbine on the output side,
The lock-up clutch is a hydraulic power transmission device with a lock-up clutch, which is equipped with an annular piston that is movably fitted into the hub of the turbine in the axial and circumferential directions and is connected to and disconnected from the front cover. The piston is divided into a first piston disposed radially outwardly of the clutch and a second piston disposed radially inwardly of the clutch, and the first piston elastically applies a rotational force to the driven plate of the turbine. The second piston has an inner cylindrical portion that fits into the hub of the turbine so as to be movable in the axial and circumferential directions, and the first piston is configured to move only in the axial direction. A friction material for clutch connection is provided on a surface of each of the first and second pistons facing the front cover in the clutch axial direction, and a friction material for clutch connection is provided on a surface of each of the first and second pistons that faces the front cover in the clutch axial direction. A hydraulic power transmission device with a multi-stage lock-up clutch, characterized in that the area is set larger than the hydraulic oil pressure receiving area of the second piston.
