PROBLEM TO BE SOLVED: To provide a liquid pressure accumulator having a structure in which a pipe is press-fitted to a connection mating member, and a pressure accumulation chamber is connected to a pump and a liquid pressure consumption device by utilizing the pipe, and capable of ignoring influence by pipe pressure-fit, and thinning the pipe.SOLUTION: In a liquid pressure accumulator, a lower end side of a pipe 3 is press-fitted and fixed to a communication hole 2a to a pump or a liquid-pressure consumption device, formed on a connection mating member 2 to liquid-tightly mount a body 1, an upper side of the pipe 3 is inserted to a passage hole 1g of the body 1, and a hole of the pipe 3 and a clearance gap found on an upper outer periphery of the pipe are applied as a liquid pressure lead-in passage 4 to a pressure accumulation chamber 1b and a liquid pressure discharge passage 5 from the pressure accumulation chamber 1b. An inner diameter expansion portion 3a is disposed on the pipe 3, and the inner diameter expansion portion 3a is liquid-tightly press-fitted into the communication hole 2a. The inner diameter expansion portion 3a of the pipe 3 may be press-fitted into an opening portion of the passage hole 1g. |
