体伝動装置の油圧制御装置。[Scope of Claim for Utility Model Registration] A fluid transmission device has an apply pressure chamber and a release pressure chamber separated by a lock-up clutch, and a lock-up control valve transfers hydraulic pressure from the release pressure chamber side to the apply pressure chamber side. When hydraulic pressure is supplied, the lock-up clutch is released and a fluid transmission state occurs, and when hydraulic pressure is supplied from the apply pressure chamber side to the release pressure chamber side, a lock-up control state is established in which rotational force is transmitted via the lock-up clutch. A hydraulic control device for a fluid transmission device with a lock-up mechanism, characterized in that a port of a lock-up control valve for discharging oil from a release pressure chamber is connected to a cooler via an oil path. Hydraulic control device of the device.
