<p>PROBLEM TO BE SOLVED: To provide an attachment structure of a lubricant heat exchanger of a gear change device which can enlarge a freedom of an arrangement position, and can avoid problems of the leakage of an internal fluid, the complication of the structure, a thermal influence and an increase of the number of part items.SOLUTION: In a heat exchanger attachment structure of a gear change device 1 which adjusts a temperature of a lubricant to a proper temperature, a heat exchanger 6 is attached to a device case 11 in a state that a base plate 7 is separated from an outer surface 2' of a device case 11, a lubricant introduction hole 7b and a lubricant derivation hole 7c are opened at a lower face of the base plate 7, connecting ends 12a, 13a of introduction/derivation tubes 12, 13 extended from the device case 11 are inserted into the introduction hole 7b and the derivation hole 7c, and the connecting ends 12a, 13a are pressure-fixed to seal faces c which are formed in the introduction hole 7b and the derivation hole 7c with flare nuts 14, 14 which are screwed into the introduction hole 7b and the derivation hole 7c.</p> |
