のオクーラ流量制御装置。[Scope of Claim for Utility Model Registration] A fluid transmission device having an apply pressure chamber and a release pressure chamber separated by a lock-up clutch locks up when hydraulic pressure is supplied from the release pressure chamber side to the apply pressure chamber side. When the clutch is released and enters a fluid transmission state, and at the same time hydraulic pressure is supplied from the apply pressure chamber side to the release pressure chamber side, a lock-up control state occurs in which rotational force is transmitted via the lock-up clutch, and this fluid transmission device In a transmission cooler flow control device configured to supply hydraulic oil to a cooler, an orifice and a cooler flow control valve are arranged in parallel with each other in an oil passage between an apply pressure chamber or a release pressure chamber and the cooler. The cooler flow control valve is capable of switching between a communicating state in which oil flows from the apply pressure chamber or the release pressure chamber to the cooler and a blocking state in which the oil flow is blocked. An ocooler flow rate control device for a transmission, characterized in that the ocooler flow rate control device for a transmission is configured to be in a cutoff state when the oil pressure is below a predetermined value, and to be in a communication state when the oil pressure is greater than a predetermined value.
