Abstract

PURPOSE:To contrive to efficiently utilize a space by arranging a ring shaped piston in an annular space formed between two internal and external cylinder tubes and fitting a base plate to the tip ends of a plurality of fixed piston rods. CONSTITUTION:An external cylinder 3 and an internal cylinder 4 are blocked by a rod cover 1 and a head cover 2 at both end portions of each of the external cylinder 3 and the internal cylinder 4, and an annular space is formed between both internal and external cylinders. A ring-shaped piston 5 is slidably disposed within this annular space. A plurality of piston rods 6 extended from the piston 5 penetrate through a rod cover 1 and projects therefrom and the base plate 7 is fitted to the leading end of the piston rod 6. Since the inner part of the internal cylinder 4 is formed into a space, other cylinder, motor or the like can be installed. Further, since piston rods are provided in plural numbers, it stops the turning of the pistons.
