Abstract
In a hose having a bent portion, a poor appearance part is prevented from being created in an inner round portion of the bent portion. A bent pipe has a bent portion located in an intermediate part in a longitudinal direction in which a cross section in a radial direction of a round of the bent portion is formed in a flat shape, and non-bent portions being continuous with the bent portion. The flat shape of the bent portion is a vertically long flat shape. With this configuration, when an unvulcanized hose is put on a mandrel and vulcanized, an inner round portion of the unvulcanized hose comes into tight contact with a bent portion of the mandrel and is not separated from the bent portion, so that the poor appearance part is hardly created in an inner round portion of the bent portion.
