A lock-up device for a torque converter transmits a torque from a front cover to a transmission-side member through a turbine. The lock-up device includes a clutch portion and a damper portion. The clutch portion includes a clutch plate and transmits the torque from the front cover toward the turbine. The damper portion includes an elastic member, a holding member and an output-side member. The elastic member attenuates a fluctuation in the torque. The holding member holds the elastic member and is provided with an engaging part integrated therewith. The engaging part is engaged with the clutch plate. The output-side member is rotatable relatively to the holding member within a range of a predetermined angle. The output-side member transmits the torque toward the turbine when the torque is transmitted to the elastic member through the holding member.

Lock-up clutch engagement hydraulic pressure learning control can be precisely performed by starting lock-up clutch engagement control and executing the lock-up clutch engagement hydraulic pressure learning control after execution of shift control is completed, in a case where the lock-up clutch engagement control is limited in a shift stage before execution of the shift control, when the shift control is executed in a state where a multi-disc lock-up clutch is released. Meanwhile, a decrease in fuel efficiency performance and a direct steering feeling is minimized by starting the lock-up clutch engagement control during shift control in a case where the lock-up clutch engagement control is not limited.

A hybrid module for a vehicle includes a torque converter and an electric motor. The torque converter includes an impeller shell and a cover.

The input-side plate has, at a plate surface of at least one side plate, multiple weight attachment holes for attaching a balance weight. Each weight attachment hole is formed in a long hole shape extending along a circumferential direction at an outer edge portion of the side plate.

A lock-up device includes a clutch part and a damper part. The clutch part is disposed between a front cover and a turbine, and transmits or blocks torque. The damper part transmits torque from the clutch part to the turbine, and absorbs torsional vibration. The damper part includes input and output members, elastic members, and a support member. The input member is connected to the clutch part. The output member is connected to the turbine. The elastic members connect the input and output members. The support member has a connecting part, a regulating part, and a stopper part. The regulating part is provided such that the output member is interposed axially between the regulating part and part of the input member. The stopper part is configured to contact the output member and prohibit the input and output members from rotating relative to each other by a predetermined angle or more.
