ABSTRACT:
A decompressing mechanism included in an internal combustion engine has a flyweight supported for swinging motion by a pin on the camshaft of the internal combustion engine, a decompression cam and an arm connecting the flyweight and the decompression cam and having the shape of a plate. The flyweight has a weight body and projections projecting from the weight body and engaged with the pin. The weight body is a block of a width along the axis of swinging motion and a thickness, along a radial direction, which are greater than the thickness, along the axis, of swinging motion of the arm. The weight body overlaps the camshaft as viewed from a direction perpendicular to a reference plane. The decompressing mechanism is small, lightweight and is capable of concentrating most of its mass on the flyweight.
