INTERNAL COMBUSTION ENGINE

[Object] To provide an internal combustion engine which increases the degree of freedom for the layout of a rocker arm and makes the rocker arm smaller in weight. [Solving Means] An internal combustion engine includes a camshaft 14 having a first exhaust cam 17A and a second exhaust cam 17B, a first exhaust valve 10A, and a second exhaust valve 10B. The internal combustion engine further includes a first rocker arm 22A for actuating the first exhaust valve 10A to open and close, a second rocker arm 22B for actuating the second exhaust valve 10B to open and close, and a decompression mechanism 28 for lifting the first rocker arm 22A in a valve opening direction at the timing of a compression stroke initiated by the internal combustion engine. The first rocker arm 22A and the second rocker arm 22B are provided with an angular movement transmitter 40 for transmitting a turning force produced by a decompression operator in the valve opening direction from the first rocker arm 22A to the second rocker arm 22B.
