Claims

[Claims for Utility Model Registration] (1) A mandrel into which an unvulcanized rubber hose having a central through hole is inserted, and two pieces fixed to both ends of the mandrel and covering both end faces of the hose and the outer periphery of both end faces. The mandrel has a circumferentially continuous engagement groove on at least one end thereof, and the cap fixed to the one end has an inner circumference approximately the same size as the outer diameter of the rubber hose. consisting of a large cylindrical body having a diameter, and a small cylindrical body extending coaxially from one end of the large cylindrical body, having an inner circumferential diameter approximately the same as the outer circumferential diameter of the mandrel, and having a through hole in its peripheral wall. A cap body, an engaging body held in the through hole so as to be freely retractable, and an engaging body held slidably in the axial direction in the central hole formed by the inner circumferential wall of the small cylindrical body, and the engaging body held in the through hole so as to be freely retractable. an inner sliding member that is biased in the direction of closing on the peripheral wall side; and an inner sliding member that is held on the outer peripheral wall side of the small cylinder so as to be slidable in the axial direction thereof, and that is biased in the direction that closes the through hole on the outer peripheral wall side. A hose flushing jig comprising: an outer sliding member that is biased; (2) The hose vulcanizing jig according to claim 1, wherein the cap has an exhaust hole that communicates the inside and outside of the cap. (3) The hose vulcanizing jig according to claim 1, wherein the outer sliding member has a flange-like operating portion protruding from its outer peripheral wall.
