PURPOSE:To make a lubricating oil passage formable in a contact part between an output shaft and a retainer, by supporting an output gear at a center between the end part and the rear part of a transmission case. CONSTITUTION:A retainer 18 fitly supporting a part 17a of an output shaft 17 is installed in the ear end of a transmission case 1 with a bolt 19' locked tight via a flange 18a. A clutch drum 8 is fitted in the circumference of this retainer 18 and supported, while a taper roller bearing 19 supporting one end part of the output shaft 17 is attached to the inner circumference of the retainer 10. In addition, a side cover 20 is connected to a rear end of the transmission case 1 for installation, and another taper roller bearing 21 supporting the other end part of the output shaft 17 is attached to the side cover 20. And, each of lubricating oil passages 23 and 24 is formed in a contact part between the part 17a of the output shaft and the retainer 18, respectively. |
