PROBLEM TO BE SOLVED: To provide a hose end correcting fixture which is used at the time of vulcanization of an unvulcanized rubber hose, has high shape stability and is hard to cause cracks or the like and gives rise to no roughening on the outer peripheral surface of the hose. SOLUTION: The hose end part correcting fixture is equipped with at least a hose inserting part having at least a cylindrical inner peripheral surface and a hose stopper part which blocks one side in the axial direction of the hose inserting part and has a circular core inserting hole coaxial to the hose inserting part at its central part. In addition, the correcting fixture is formed of a synthetic resin material which shows a thermal deformation temperature of 70°C or higher under the load of 1.82 MPa according to ASTM D648 and a breaking strength value equivalent to or higher than 30% of an initial one after the lapse of 750 hours in a steam atmosphere of 160°C.
