Abstract
A hose connecting structure includes a hose whose central and engaging portion having a thermal flexibility resin which is molded by a blow molding method and a mating member which is inserted into the edge opening of the hose. The hose connecting structure further includes a ring-shaped sealing material and a first engaging portion which is disposed in the axial direction by a predetermined distance to the sealing material at either the edge portion of the hose or the mating member and a second engaging portion which is directly or indirectly engaged with the first engaging portion at either the edge portion of the hose or the mating member. Since the central and the engaging portion of the hose connecting structure includes a thermal flexibility resin which is molded by a blow molding method, the most suitable soft and hard resin for the appropriate portion can be used. When the engaging portion with the mating member and the central portion are molded integrally, the working efficiency is improved. The sealing material such as an O-ring is used for the engaging surface. Therefore, soft resin is not used for the engaging surface, and a free selection of resin is achieved. Moreover, the polishing of the engaging surface is not required.
