<p><P>PROBLEM TO BE SOLVED: To provide a cooling structure of a vehicular transmission capable of dropping the atmospheric temperature around an exhaust muffler device and preventing ingress of foreign matters in the transmission from a cooling air outlet. <P>SOLUTION: In the cooling structure of the vehicular transmission, an engine unit with an engine body and a transmission integrated with each other is mounted behind a steering device and on a substantially center lower part of a vehicle body frame 2, an exhaust muffler device 31 with an upper part thereof covered by a fender 18 is arranged on one rear side of the engine unit, cooling air is led into a storage part of the transmission from the outside via an introduction duct, and cooling air to cool each member is discharged into the atmosphere via an outgoing duct 39. The outgoing duct 39 extends backward of the vehicle from the transmission, a most downstream end thereof is arranged in a vicinity of the exhaust muffler device 31, and a discharge port 41 of cooling air is opened toward the peripheral space of the exhaust muffler device 31 at the most downstream end. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
