装置。[Scope of Claim for Utility Model Registration] 1. In a shaft sealing device for the sliding part of a needle valve stem of a painting spray gun in which the needle valve stem penetrates through the inner diameter, the back surface of the low pressure side is flattened and brought into contact with the packing pusher, and the high pressure side A ring-shaped main packing having a rectangular recess formed in the axial direction on the front surface of the main packing is fitted, and a ring-shaped sub-packing having rubber elasticity is fitted into the rectangular recess of the main packing, and the sub-packing faces the high pressure side. A shaft sealing device for a needle valve sliding part of a painting spray gun, in which a packing receiver having a mountain-shaped convex part that presses the center part of the packing is fitted so as to be pressed against the sub packing by a disk spring. 2. The secondary packing is made of a rubber elastic material such as natural rubber, nitrile rubber, fluorine rubber, silicone rubber, Thiokol (registered trademark), chloroprene rubber, urethane rubber, etc. The coating spray described in item 1 of the utility model registration claims Shaft sealing device for gun needle valve sliding part.
