PROBLEM TO BE SOLVED: To provide a hydraulic piping hose capable of suppressing the narrowing of a flow path of a hydraulic fluid accompanied with clamping while keeping a mouthpiece in small size and suppressing the coming-off of a hose or the leakage of liquid, a brake hose, and a hose mouthpiece.SOLUTION: A hydraulic piping hose includes: a mouthpiece 3 which integrally has a cylindrical nipple portion 31 formed with a flow path 310 of a hydraulic fluid, a cylindrical socket portion 32 formed on an outer periphery of the nipple portion 31, and a coupling portion 33 coupling the nipple portion 31 and the socket portion 32; and a hose body 2 clamped and fixed between the nipple portion 31 and the socket portion 32. The socket portion 32 has a first cylinder portion 321 formed in a predetermined range from the other end 32d toward one end 32c; and a second cylinder portion 322 formed between the first cylinder portion 321 and the coupling portion 33, having an inner diameter smaller than an inner diameter of the first cylinder portion 321, and formed with a clamping portion 4 for fixing a hose body 2.SELECTED DRAWING: Figure 1

    【課題】口金具を小型に維持し、かつ、ホースの抜けや液漏れを抑制しつつも、加締めに伴う作動液の流路の狭小化を抑制することが可能な液圧配管用ホース、ブレーキホース、及びホース用口金具を提供する。【解決手段】作動液の流路310が形成されている円筒状のニップル部31、ニップル部31の外周に形成されている円筒状のソケット部32、及びニップル部31とソケット部32とを連結している連結部33を一体に有してなる口金具3と、ニップル部31とソケット部32との間に加締め固定されているホース体2とを備え、ソケット部32は、他端32dから一端32cに向かって所定の範囲に形成された第1の円筒部321と、第1の円筒部321と連結部33との間に形成され、第1の円筒部321の内径よりも小さい内径を有し、ホース体2を固定する加締め部4が形成された第2の円筒部322と、を有している。【選択図】図1
