<P>PROBLEM TO BE SOLVED: To provide lubricating structure for a vehicular transmission with superior lubricity, capable of reducing agitation resistance. <P>SOLUTION: The lubricating structure for a vehicular transmission has a final gear 43 rotating with a lower end portion dipped in lubricating oil stored in a lubricating oil reservoir part 7 formed in a transmission case 2, and it is provided with a suction opening 51 opened in a predetermined oil level position of the lubricating oil reservoir part 7, a lubricating oil suction passage 52 communicating the suction opening 51 with a lubricating oil tank 53, a lubricating oil return circuit 54 communicating the lubricating oil tank 53 with a transmission case 2 interior, and a lubricating oil tank decompressing means 60 for repeating decompression and atmospheric release of a lubricating oil tank 53 interior by intake pipe negative pressure supply of an engine. An oil level L1 of lubricating oil stored in the lubricating oil reservoir part 7 is retained at the height position of the suction opening 51, and agitation loss is suppressed by agitation resistance of the final gear 43. <P>COPYRIGHT: (C)2008,JPO&INPIT |
