PROBLEM TO BE SOLVED: To efficiently cool down a hydrostatic continuously variable transmission arranged in an engine mounted in a traveling machine body with its output shaft positioned laterally or in either of the front and the back of the engine by means of a comparatively simple and reasonable improvement. SOLUTION: Engines 23, 50 provided with a first cooling fan 41 are mounted in a traveling machine body 1 with their output shafts 23a, 50a positioned laterally, and a second cooling fan 48 is mounted to an input shaft 24a in a static hydraulic continuously variable transmission 24 transmitted and connected to the output shafts 23a, 50a via a belt type transmission mechanism 25. The cooling air flowing direction by the first cooling fan 41 and that by the second cooling fan 48 are matched with each other.
