コンプ装置。 A decompression shaft that forcibly rotates the locker arm and moves the valve stem in the valve opening direction is brought into contact with the locker arm that contacts the valve stem,
A biasing body that holds the rocker arm in a forced rotation position is engaged with the decompression shaft when the engine is cranked, and the biasing body is biased by negative pressure in the crank chamber when the engine speed increases. An engine decompression device characterized by being connected with a negative pressure sensitive device that moves a decompression shaft against force and releases forced rotation of a rocker arm.
