<p>PROBLEM TO BE SOLVED: To provide a noise insulation cover for transmission improving the cooling performance of a transmission. SOLUTION: This noise insulation cover is structured so that running wind may run through the inside of a cover body 15a smoothly by disposing it so as to cover the periphery of the transmission 6 and forming a venturi section S (a throttle section) for throttling a clearance 31 to a transmission wall surface at the inner surface of the cover body 15a shielding the noise from the transmission to increase the wind velocity of the running wind running through the clearance 31. Thus, the heat of the transmission 6 is led out to the open air by the running wind immediately without remaining inside the cover body 15a.</p> |
