内燃機関のデコンプ装置。 A decompression weight is pivotally attached to the side of the cam gear so that it rotates due to centrifugal force, a spacer is rotatably fitted to the camshaft, an engaging portion that transmits the rotation of the decompression weight to the spacer, and a decompression weight that is close to the cam. a pin hole that perpendicularly penetrates the camshaft at a position where the decompression pin is slidably inserted into the pin hole; and a cam portion formed on the spacer at a position in contact with the base end of the decompression pin. During low-speed rotation, the base end of the decompression pin is pressed against the cylindrical inner peripheral surface of the spacer, and the tip of the decompression pin protrudes from the cam surface to perform decompression, and during high-speed rotation, the base end of the decompression pin fits into the cam part of the spacer. A decompression device for a four-stroke internal combustion engine, characterized in that the tip of the decompression pin is retracted from a cam surface and loses its decompression function.
