特徴とするエンジンのデコンプ装置。 A release lever with a flyweight on one side is placed around the camshaft side between the cam gear and the cam, and a mounting member with a bearing that rotatably supports the release lever is fixed to the end face of the cam gear. On the other hand, the release lever is characterized in that the end thereof is provided with a notch formed so as to sink into the cam operating surface when the release lever rotates due to an increase in centrifugal force, and to protrude from the cam operating surface when the centrifugal force decreases. engine decompression device.
