Abstract

PURPOSE: To obtain a low cost ram which surely can obstruct a leak of a fluid by a method wherein a cylindrical elastic expansion body having sealed both ends is formed in a sealing constitution and coil springs are installed in the expansion body by supress an expansion in a radial direction.
CONSTITUTION: A cylindrical elastic expansion body 1 having sealed both ends is formed in a sealing constitution and coil springs 2 or rings are installed in this expansion body 1 to supress the expansion in radial direction. And in order to constitute the ram, end plates 3, 4 are installed at both end parts of the expansion body 1 and a mouthpiece 6 opening to a fluid filling space 5 to be formed in the inside of the expansion body 1 is installed at an end part of the expansion body 1. This ram is used, for example, in an oil pressure transfer device, and it is extended to a axial direction by supplying a pressure fluid from the mouthpiece 6. At this time, the expansion of the ram in the radial direction is obstructed by the coil springs 2 or rings, thus, the ram is expanded only to the axial direction.
