PCT No. PCT/JP84/00361 Sec. 371 Date Mar. 17, 1986 Sec. 102(e) Date Mar. 17, 1986 PCT Filed Jul. 11, 1984 PCT Pub. No. WO86/00673 PCT Pub. Date Jan. 30, 1986.Disclosed herein is a slide cylinder basically consisting of a cylinder block internally defining a plural number of intercommunicating cylinder bores in parallel relation with each other, a piston and a piston rod fitted in each cylinder bore, and plate-like cross members integrally connecting the respective piston rods at the opposite ends thereof. The drive chambers defined by the pistons are communicated with fluid supply/discharge ports at the opposite ends of one of the piston rods and one of fluid supply/discharge ports provided in the cylinder block, permitting a diversity of piping modes by selective use of these ports. When installed upside down, it is possible to move either the cylinder block or cross plates whichever is desired. The slide cylinder can transfer loads accurately without involving rotational motion. Fixing of a piston against a piston rod is by means of caulking the ends of cylindrical portion of a piston at fixing grooves of a piston rod. This fixing work is simple and no backlash is permitted. A position sensor that permits applications for various purposes is easily installed.
