PURPOSE: A traction type accumulator is provided to enable an accumulator to perform the moving operation more stably by installing a connection member which hangs on a crane and is moved. CONSTITUTION: A traction type accumulator comprises a shell member(1), a bladder(7), a cover member(10), and a connection member(20). Hydraulic fluid fills the shell member. The bladder is inserted into the shell member and is filled with working gas. The cover member is installed at the bladder to control the inflow and the outflow of the working gas. The connection member is connected to the cover member or is separated from the cover member. A screw thread is formed at the junction of the connection member and the cover member to couple them. The connection member comprises a hook(29) drawing the bladder.
