プ装置。 A cam on which the valve tappet slides is formed on the camshaft, a lifter having a wrist portion at one end that lifts up the valve tappet by protruding outside the base circle of the cam is disposed on the camshaft, and a centrifugal force is applied to the other end of the lifter. At the same time, an elastic body is provided that urges the lift portion of the lifter in a direction to cause the lift portion of the lifter to sink into the base circle of the cam. A centrifugal decompression device for an engine, characterized in that the lifter has a relief portion that absorbs the biasing force of the elastic body when the cam is inserted into the base circle of the cam.
