Abstract

An insert section of an insert member is inserted into a tube member in a state in which the insert member is detached from a recess to form a diametrally expanded section on the tube member. Subsequently, the insert member is fitted to the recess to install the tube member to the recess. At this stage, an outer circumferential surface of an expanded section of the insert member tightly contacts with an inner circumferential surface of the recess to effect the sealing function. Subsequently, a tapered section and an outer circumferential surface of the tube member are resin-welded by using a welding material. Thus, the tube member is prevented from disengagement from a body.
