The automatic grease injection system(3) is installed on the oil drain tube(2) of the stroke system(1) and by connecting this injection system to the chisel sliding part(5) of the stroke system through the grease hose(4), the grease inside the injection system is automatically supplied to the chisel sliding part. The automatic grease injection system is constructed with the injector(7) which installed between the bottom of the grease storing container(6) and the top of the oil drain-pipe but form the injector into the top, bottom, and middle body parts(7a,7b,7c) each and place the diaphragm(8) in between each body parts. At the inflow path(9) which formed at the upper part of the upper body part, the ball(10) is placed and the grease discharge gate(11) on the side of the upper body part, and on the bottom of the lower body part, the working fluid entrance(12) is formed. When the vibration is generated in the stroke system body(13), the grease in the storing container is supplied automatically to the chisel sliding part to lubricate by receiving the force in the down direction due to inertia.
