    Abstract: In a camshaft for an internal combustion engine, integrally including: a shaft main portion that extends linearly; a plurality of valve-actuating cams disposed to be spaced apart from each other in an axial direction of the shaft main portion; and a pair of support arms extending along one diametric line of the shaft main portion radially outwardly from one end part of the shaft main portion and being fitted with a follower rotational body, a pair of overhangs are integrated with the shaft main portion and the pair of support arms, the overhangs extending between the support arms in a peripheral direction of the shaft main portion, and a thick-wall portion having a larger thickness in a direction along an axis of the shaft main portion is formed in part, on a radially outer side of the shaft main portion, of each of the overhangs.

    Abstract: An internal combustion engine for increasing the freedom of the layout of a rocker arm wherein the rocker arm is lighter. The internal combustion engine includes a camshaft having a first exhaust cam and a second exhaust cam, a first exhaust valve, and a second exhaust valve. The internal combustion engine further includes a first rocker arm for actuating the first exhaust valve to open and close, a second rocker arm for actuating the second exhaust valve to open and close, and a decompression mechanism for lifting the first rocker arm in a valve opening direction at the timing of a compression stroke initiated by the internal combustion engine. The first rocker arm and the second rocker arm are provided with an angular movement transmitter for transmitting a turning force produced by a decompression operator in the valve opening direction from the first rocker arm to the second rocker arm.
