PROBLEM TO BE SOLVED: To effectively lubricate a one-way clutch supported on the outer circumference of a rotary shaft of a transmission with lubricating oil supplied from within the rotary shaft.SOLUTION: A radially inward end of a washer 59 is abutted on an inner race 57a of a first bearing 57, and a seal surface 59a provided on a radially outward end of the washer 59 is abutted on an outer race 51b of a second bearing 51. Therefore, an axial load acting on a second gear 24 can be supported by a second rotary shaft 14 via the outer race 51b of the second bearing 51, the washer 59, and the inner race 57a of the first bearing 57. Furthermore, a lubricating-oil guide surface 59c guiding lubricating oil supplied from within the second rotary shaft 14 to a one-way clutch 23 via the second bearing 51 is formed on a second bearing 51-side side surface of the washer 59. It is, therefore, possible to efficiently supply the lubricating oil to the second bearing 51 and the one-way clutch 23 and to improve the lubrication effect. |
