A jointed assembly, a power treating device, an assembling method of the jointed assembly, and an assembling jig are provided to install an engaged part, where a receiving jig is engaged, on the outside of one of jointing and jointed members during welding, thereby removing an unnecessary protruded part such as a flange or the like, making miniaturization possible and providing stable joint. A jointed assembly comprises the followings: a jointing member(1) capable of being jointed by having at least an end face as a welded part(5); and a jointed member(2) having a joint receiving part(3) to which the end face of the jointing member(1) is joined. On the outside of at least one of the jointing and jointed members(1,2), an engaged part(4) is installed, wherein a receiving jig(6) is engaged when the jointing and jointed members(1,2) are welded to each other by a heat welding method. A part, where the welded part(5) is inserted between the engaged part(4) and the jointed member(2) among the outside of the other one of the jointing and jointed members(1,2), is an abutting surface of a welding jig(7).
