とする内燃機関の減圧装置。In an internal combustion engine that opens and closes an intake valve and an exhaust valve by rotation of a cam provided on a camshaft, an auxiliary cam rotatably fitted to the camshaft and supported by a support body that rotates together with the camshaft are used. and a centrifugal arm that rotates due to the centrifugal force generated by the rotation of the camshaft. A pressure reducing device for an internal combustion engine, characterized in that the weight portion is biased by a spring in a direction toward the center of rotation of the camshaft, and the auxiliary cam advances the closing timing of the intake valve or the exhaust valve in proportion to the centrifugal force. .
