Claim:
1. A heat exchanging device of lubrication oil for exchanging heat of the lubrication oil which circulates in a transmission for a vehicle, comprising: a first lubrication oil circulating circuit through which a first lubrication oil circulates to be supplied to a friction engaging device of the transmission; a second lubrication oil circulating circuit through which a second lubrication oil circulates to be supplied to mechanisms other than the friction engaging device of the transmission; a cooling water circulating circuit through which a cooling water circulates to cool a driving source of the vehicle; a first heat exchanger for exchanging heat between the first lubrication oil and the second lubrication oil; and a second heat exchanger for exchanging heat between the first lubrication oil and the cooling water.
