PURPOSE: To provide an industrial vehicle wherein overheat of an engine is prevented, and attaching work for circulating pipes for circulating tor-con oil is easy, and also the circulating pipes are not heated by the engine.

CONSTITUTION: In an industrial vehicle 1 provided with a torque converter 2 for transmitting power generated by an engine 11 to wheels 12 and an operating oil tank 3 for housing operating oil by which loading work is performed, and wherein the torque converter 2 is arranged adjacent to the operating oil tank 3, a heat exchanger 4 for cooling tor-con oil to be used for the torque converter 2 is arranged in the operating oil tank 3. And circulating pipes 221, 222 for circulating tor-con oil are interposed between the heat exchanger 4 and the torque converter 2. The heat exchanger 4 is formed by a box-like body or a pipe-like body.
