るエンジンのデコンプ装ｔ。In a device that opens and closes intake valves and exhaust valves with respect to a combustion chamber by operating a cam provided on the camshaft with the rotation of a camshaft that receives rotational force from a crankshaft in a cam gear. A pin parallel to the axis of the camshaft is formed on the end face of the force gear, and a release lever having a flyweight on one side is rotatably inserted into this pin hole, and the end of the release lever on the side opposite to the flyweight is inserted. extends toward the cam side, and a notch is provided in a portion of the end of the release lever facing the tappet end so that the release lever protrudes and retracts from the force surface when the release lever rotates; A retaining part is provided on the flyweight,
and a weight lever having one end pivotally connected to the force gear end face and the other end engaged with the locking part, and the combustion chamber is brought into a semi-compressed state by protrusion of the release lever end from the cam surface, A decompression device for an engine characterized in that a combustion chamber is brought into a fully compressed state by recessing an end of a release lever into a cam surface.
