Abstract

PURPOSE:To easily disassemble and assemble the spring device by restricting a free extension of a spring when the spring body is separated from pistons. CONSTITUTION:When a valve 10 is opened, pistons 18a, 18b ascend to push up a spring bearing 30. And inside peripheral projection 29 of the spring bearing 30 is located above a spring presser sleeve 27. When the value 10 is closed, a piston 18 is lowered by the force of a spring 32. At this time, the inside peripheral projection 29 is situated slightly above an outside peripheral projection 28. When a cylinder cover 25 is removed from a cylinder 20 during disassembly and assembly, the spring 32 which is an integral part of the cylinder cover 25 is separated from the pistons 18a, 18b. Then, the spring 32 can extend until the inside peripheral projection 29 of the spring bearing 30 strikes the outside peripheral projection 28 of the spring presser sleeve 27, but further extension of the spring is restricted.
