PROBLEM TO BE SOLVED: To enhance lubrication performance of a bearing by a simple mechanism. SOLUTION: An output shaft 10 of a transmission 1 is rotatably supported by a rolling bearing 12 and a bush 15. A shift rod 7 operated by a change speed lever 6 is slidably and rotatably supported by a bush 21. Lubrication oil is guided by a pipe 17 from the inside of a transmission case 3 to the inside of an extension case 5 to immerse, into the lubrication oil in the extension case 5, the lower part of an impeller 20 mounted to the output shaft 10 adjacently to the rolling bearing 12. Oil passages 22 and 23 for making the inside of the extension case 5 communicate with the inside surfaces of the bushes 15 and 21 are formed on a wall surface 14. COPYRIGHT: (C)2004,JPO
