The brake pedal has a problem in that it has a large amount of friction and causes a floppy feeling when the brake pedal is depressed, and to eliminate this, the weight must be increased in order to improve the rigidity of the wheel cylinder or caliper.
本発明は特許請求の範囲に記載されたように構成されて
いるため上記不具合を解消できるものである。Since the present invention is configured as described in the claims, the above-mentioned problems can be solved.
以下９本発明の一実施例について具体的に説明する。Hereinafter, nine embodiments of the present invention will be specifically described.

ゴムチューブ６からなっている。In the drawing, a brake hose 1 has an inner rubber tube 2 through which brake oil flows. A first reinforcing body 6 formed by knitting aromatic polyamide fibers (for example, "Kefler" manufactured by Du Pont) attached to the outer peripheral surface of the inner rubber tube 2 with an adhesive 7. The same first reinforcement body 3
4. An intermediate rubber tune formed in close contact with the outer periphery of the 4. A second reinforcing body 5 is formed around the outer periphery of the intermediate rubber tube 4 by weaving aromatic polyamide fibers in the same manner as the first reinforcing body 3.
It consists of an outer rubber tube 6 fixed to the outer periphery of the second reinforcing body 5 with an adhesive 8.

止されるので。The elongation of the aromatic polyamide fibers forming the first and second reinforcing bodies 3.5 is extremely small, and the first reinforcing bodies 3 are bonded to the inner rubber tube 2, and the second reinforcing bodies 5 are bonded to the outer tube 6. Therefore, the expansion of the inner rubber tube 2 and the outer rubber tube 6 is prevented by the first and second reinforcing bodies 3 and 5.
ブレーキホース１の膨張量は０．０５〜０．０５ＣＣ／

小さくなる。The expansion amount of brake hose 1 is 0.05 to 0.05 CC/
feet (at 70 K9/mrll).
したがって、フレーキオイルの量を少なくでき。Therefore, the amount of flake oil can be reduced.

I can do it.
