Abstract
A projection is formed on the outer circumference of an annular member and a stopping member is attached to a cylinder head supporting a camshaft thereon. A side surface of the projection comes into contact with a side surface of the stopping member to restrain a decompression cam from turning when the camshaft rotates in the normal direction. The stopping member does not apply any pressure to the annular member in a radial direction and the annular member does not exert any force on the camshaft. Consequently, frictional resistance against the rotation of the camshaft can be reduced and a loss in the output of the engine can be suppressed.
