Abstract

Disclosed is a decompression device of an internal combustion engine, including: a decompression cam which has a built-in one-way clutch operative for transmitting torque only when a cam shaft is reversely rotated and is attached to one end of the cam shaft; and a stopper piece for stopping an operation of the decompression cam when the cam shaft is forwardly rotated, which is attached to a cam shaft holder used together with a cylinder head for supporting the cam shaft.
