置。 A pressure accumulator that is incorporated into the piping of a hydraulic power brake and supplies hydraulic oil to the brake wheel cylinder when the brake valve is operated in a state where pressure oil from the hydraulic pump is no longer sent to the brake valve, In a cylindrical body with both ends closed, a pressure accumulating cylinder having a smaller diameter and shorter than the body is installed almost concentrically, and one end of the accumulating cylinder is fixed to one end of the body, and the accumulating cylinder is slidably inserted into the accumulating cylinder. The rod of the piston extends into the body, and the spring receiver is movably disposed on the fixed end side of the pressure accumulating cylinder in the body, and the end of the rod is disposed outside the pressure accumulating cylinder. A pressure accumulating device for an industrial vehicle, which is connected by a connecting member, and further includes a pressure accumulating spring housed on a wall side in the body so as to surround the outside of the connecting member.
