Abstract

In a vehicle power unit, a main shaft and a counter shaft of a transmission are placed in and taken out through an opening formed on the crankcase. The main shaft and the counter shaft are rotatably held by a single transmission cover fastened to the crankcase and a cylinder block for covering the opening. In addition, the output shaft is provided with an input gear engaged with an output gear provided on a counter shaftand is rotatably supported on the transmission cover by a bearing holding portion formed on the transmission cover via a ball bearing. The counter shaft and the output shaft are connected via a pair of gears, wherein the necessity of increasing the fastening rigidity with respect to the transmission cover is reduced and the accuracy of the position and the size of the mounting positions of the counter shaft and the output shaft is easily secured with the aforementioned power unit.
