Abstract

A decompression apparatus includes: a cam shaft having exhaust cams that each open an engine exhaust valve; a release pin rotatable about an axis parallel to the cam shaft between decompression and decompression release positions; a decompression plate fixed to the cam shaft with an opening where the cam shaft is inserted; a weight swingably attached to the decompression plate, radially outward by a centrifugal force; a biasing unit that biases the weight radially inward; and an interlocking mechanism that rotates the release pin with the rotation of the weight. A first flat section is formed on an inner peripheral edge of the opening. The cam shaft has a second flat section that abuts against the first flat section and a supporting surface on a same plane as the second flat section. The outer peripheral surface of the release pin abuts against and slides on the supporting surface.
