Abstract
A decompressor for an internal combustion engine that is capable of preventing the dropping-off of the decompression shaft during maintenance work includes a falling-off prevention pin inserted into a pin insertion hole having an opening to the outer circumferential surface of a camshaft and intersecting, at least partially, an insertion hole. A decompression shaft is inserted and fitted into the insertion hole. The falling-off prevention pin engages with the decompression shaft while the decompression shaft is allowed to rotate. The decompression shaft is prevented from moving in the axial direction of the decompression shaft. The opening of the pin insertion hole of the camshaft into which the falling-off prevention pin is inserted is blocked by a bearing. A swing portion includes a bearing-restriction portion formed so as to protrude towards the bearing. The bearing-restrict portion restricts the movement of the bearing in the axial direction of the camshaft.
