TEMPERATURE CONTROL DEVICE OF LUBRICATING OIL

PROBLEM TO BE SOLVED: To supply lubricating oil having a raised temperature at the time of warming-up of an warming-up object without increasing the size of a thermal storage tank. SOLUTION: A strainer 14 filtering lubricating oil and supplying it to a transmission T is equipped with: a first lubricating oil suction port 29 which sucks lubricating oil with low temperature stored in an oil pan 11; and a second lubricating oil suction port 30 which sucks lubricating oil with high temperature stored in the thermal storage tank 12. The opening and closing of the first and second lubricating oil suction ports 29, 30 are controlled by a flow control valve 32. The temperatures of the strainer 14 and the transmission T are speedily raised, and flow resistance in the event of the lubricating oil passing through the strainer 14 is reduced, and the transmission T is speedily warmed up by supplying the lubricating with high temperature in the thermal storage tank 12 from the second lubricating oil suction port 30 through the strainer 14 to the transmission T when the operation of the stopped transmission T is started.
