Abstract

PURPOSE:To make a piston lightweight and prevent loosening of screws by connecting a piston cap and a piston base by means of screws and forming grooves on a part of one or bath screws. CONSTITUTION:The male screw part 13a is formed on the contracted outer diameter part at the top end part of a piston base 13, and on the outside of the male screw part, the flat stepped part 13b is formed. On the other hand, on the inner surface of the opened end of a piston cap 14, the female screw part 14a which is screwed with the male screw part 13a is formed, and on a part of the female screw part, an annular groove 19 is formed. Therefore, in fabrication, the cap 14 is tightened, then the female pscrew part 14a on both sides of the groove 19 is deformed elastically and a force F is generated, and the female part bites into the male screw part 13a firmly, and loosening of screw can be prevented.
