Abstract

A decompression device is provided for an internal combustion engine having a cylinder head provided with a pair of left and right camshaft bearings sandwiching intake valves and exhaust valves with a structure that is both simple and small. A camshaft is provided having cam projections for at least a pair of intake cams between camshaft side bearings corresponding to the pair of left and right bearings, and a decompression member with a decompression cam with a centrifugal weight arranged at a camshaft end passing through the bearing close to the camshaft end so that a tip thereof is arranged in the vicinity of the cam projections, with the decompression member comprising the centrifugal weight, the decompression cam, and a rotatable shaft coupling the centrifugal weight and the decompression cam in an integral manner.
