プ装置。In a device in which a tappet is operated by a cam provided on the camshaft as the camshaft rotates to open and close an intake valve and an exhaust valve for a combustion chamber, an axial hole is formed in the axial center of the camshaft, and the axial hole is formed in the axial center of the camshaft. A slidable piston is inserted into the cam, a biasing body is provided to bias the piston in the axial direction, and a groove is formed in a side portion of the camshaft near the cam to communicate with the shaft hole and to be elongated in the axial direction. A decompression pin protruding slightly higher than the cam surface is inserted through the groove and protrudes from the piston, while a solenoid device that operates the solenoid shaft by a power generation device generated by engine rotation is provided at the shaft end of the camshaft. the solenoid shaft is provided so as to face each other, the solenoid shaft is brought into contact with the shaft end of the piston, and when the engine is stopped or rotates at low speed, the piston is moved to one side by the biasing body, and the decompression pin is brought into contact with the tappet end. to bring the combustion chamber into a semi-compressed state, and as the rotation of the engine increases, the solenoid shaft is activated to move the piston to the other side against the biasing force of the biasing body, thereby retracting the decompression pin from the end of the tappet and combustion. An engine decompression device characterized in that a chamber is brought into a fully compressed state.
