PROBLEM TO BE SOLVED: To increase a rate of oil led into a feed passage in a counter shaft, and sufficiently supply oil to each part by arranging a cutout part on a bulk head formed between housing parts of two bearings of a transmission case, and leading oil in the housing part of one bearing into the housing part of the other bearing. SOLUTION: When an oil pump is driven, oil which falls from a driving gear 65 side and kept in a counter gear 60 part is scrapped up by rotation of the gear 60, and is led to a bottom part side of a housing part 70 through a circular cone shaped rolling bearing 28b. The oil is guided to a flange part 74 of an oil gutter 75 and a cylindrical part 73, and is led to a main feed passage 62. Oil reserved in the housing part of the circular cone shaped rolling bearing of an intermediate gear side is jointed at the housing part 70 through a cutout groove 76. Oil in the main feed passage 62 is supplied to one way clutch 63 installed on an end part of a counter shaft 27, flows out to a side part of a cylindrical rolling bearing 26 through an auxiliary feed passage 64, and is supplied to the cylindrical rolling bearing 26, a gear engaging part, and the like. |
