<P>PROBLEM TO BE SOLVED: To provide a transmission for automobile in which the oil guided to the edge part of a counter shaft is effectively guided to a center hole and is made available for lubrication. <P>SOLUTION: In the transmission for automobile, the rear part of a counter shaft 16 extended back and forth by a tapered roller bearing 18 using a tapered roller 18a that reduces diameter toward the rear side as a roller is supported by a gear case 11 and a center hole 16e for lubrication is formed along a shaft core from the rear edge of the counter shaft 16. An enclosed region 26 contacting with the tapered roller bearing 18 is formed around the counter shaft 16 on the rear side of the tapered roller bearing 18 and a communication hole 16h which connects the enclosed region 26 to the center hole 16e is formed on the counter shaft 16. A ring shape support piece 21 to which the tapered roller bearing 18 is inserted is formed on the gear case 11 and a ring shape oil seal 27 is disposed between the outer circumference of the counter shaft 16 on the rear side from the tapered roller bearing 18 and the inner periphery of the ring shape support piece 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
