構成したことを特徴とするエンジンのデコンプ装置。In a device that operates a tappet by a cam provided on the camshaft by the rotation of the camshaft that receives rotational force from the crankshaft at the cam gear to open and close the intake valve and the exhaust valve for the combustion chamber, the force gear is applied to the end face of the gear. A parallel pin hole is formed in the axis of the camshaft: This pin hole'
A release lever provided with a flyweight on one side is rotatably inserted into the release lever, and an end of the release lever on the side opposite to the flyweight extends toward the cam, and a portion of the release lever end faces the tappet end. A notch is provided in the camshaft so that the release lever protrudes and retracts from the cam surface when the release lever rotates, and a stopper part that limits the rotation of the flyweight on the camshaft on the flyweight side and a shaft of the release lever. A sleeve made of resin or the like is integrally formed with a retaining part that restricts movement in the direction, and the release lever end protrudes from the cam surface.
A decompression device for an engine, characterized in that the combustion chamber is in a semi-compressed state, and the combustion chamber is brought into a fully compressed state by recessing the end of the IJ-slever into a cam surface.
