給装置。[Claims for Utility Model Registration] 1. A diaphragm is attached to the opposite end of the plunger that slides inside the cylinder, the open end of the diaphragm is fixed to the main body, and the diaphragm forms a pneumatic chamber on the opposite side of the cylinder. In the grease supply device, the supply of air pressure to the pneumatic chamber is controlled via a solenoid valve, and the solenoid valve has a valve body that moves up and down, and a supply side that is selectively seated by this movement. A valve seat, an exhaust side valve seat, a plunger that comes into contact with a rod integrated with the valve body, a spring that acts so that the valve body is pressed against the supply side valve seat via this plunger, and this spring. A grease supply device comprising: a coil that moves the plunger against the force of movement of the plunger. 2. The spring engages one end with an annular groove formed on the outside near the lower end on the valve body side of the plunger,
The grease supply device according to claim 1, wherein the other end is in contact with the lower end of the coil.
