摘要：
An intake cam and an exhaust cam are formed integrally with a cam shaft, and a decompression cam is additionally provided adjacently to the front side of the exhaust cam. A rib is formed in back of the intake cam. A cylindrical surface portion having a diameter being the same as that of the outer periphery surface of a ball bearing for supporting the front portion of the cam shaft and being larger than the diameter of the base circle of the cam shaft, is formed on the front crank case, and a locking stepped portion is formed in back of the cylindrical surface portion. Cutout portions are formed in the locking stepped portion so that the cam shaft can be pulled forward in the state that the intake cam, exhaust cam and the decompression cam are arranged.
