  • the axial direction of the sleeve portion 2b of the covering cap 2 is almost the same as in the example shown in FIG.
  • the reinforcing hose 1 By injecting the adhesive 5 from the injection port 5a opened in the intermediate position, the reinforcing hose 1 extends and extends in the axial direction and the circumferential direction along the lattice-shaped second passage 4b in the axial direction and the circumferential direction, A part of the adhesive 5 flows into the first passage 4a, and an openable / closable air vent channel 5b formed between the inner end surface 2c of the ring portion 2a and the outer peripheral surface 3a of the sealing member 3 or slightly.
  • the air in the first passage 4a is expelled from the gap by the increase in internal pressure, and the adhesive 5 protrudes as necessary, so that the entire first passage 4a is filled with the adhesive 5.
  • the remaining adhesive 5 flows to the end of the second passage 4b, so that the openable and closable air vent formed between the tip surface of the annular convex portion 2h and the outer peripheral surface 1c of the reinforcing hose 1 is formed.
  • the air in the second passage 4b is expelled from the working flow path 5b or a slight gap due to an increase in internal pressure, and the adhesive 5 protrudes as necessary, so that the entire second passage 4b is filled with the adhesive 5.
  • the adhesive flows into a slight gap formed between the tip surface of the convex portion 2 e 2 of the concave and convex portion 2 e and the outer peripheral surface 1 c of the reinforcing hose 1.
  • the adhesive 5 is not only the entirety of the second passage 4b, but also the outer surface of the reinforcing hose 1 and the convex portion 2e2 of the concave and convex portion 2e as required, as compared with the first embodiment shown in FIGS.
  • the entire gap 1c flows evenly and the adhesive 5 can be filled without residual air.
  • the volume of the second passage 4b is smaller than that of the first embodiment shown in FIGS. 1 to 3, the time required for filling the adhesive 5 can be shortened, and the manufacturing cost can be reduced. There is.
  • a plurality of protrusions 2d are integrally formed on the end surface of the ring portion 2a at predetermined intervals in the circumferential direction, and a plurality of convex portions are formed as uneven portions 2e on the inner peripheral surface of the sleeve portion 2b.
  • 2e1 is integrally formed at predetermined intervals in the axial direction and the circumferential direction, or a plurality of convex portions 2e2 having flat tip surfaces are formed close to each other in the axial direction and the circumferential direction, respectively, but is not limited thereto.
  • a protrusion extending in the circumferential direction is intermittently integrally formed as the protrusion 2d, or a protrusion or a groove extending in the axial direction and the circumferential direction is integrally formed as an uneven portion 2e on the inner peripheral surface of the sleeve 2b, You may do it. In these cases, the same effect as the above-described embodiment can be obtained.
  • the reinforcing hose 1 knits the reinforcing wire 1a into a cylindrical shape between the inner layer 1i and the outer layer 1o to form a reinforcing layer integrally with the inner layer 1i and the outer layer 1o.
  • reinforcement wire rods such as winding a plurality of reinforcement wire rods 1a into a lattice shape, etc.
  • the number and winding shape of 1a are arbitrary.
