ABSTRACT OF THE DISCLOSURE An article, obtained by injection molding, includes a first member on which an electrical element such as a coil is provided or mounted and a second member, surrounding the first member, formed integrally therewith. A first radially inward projection of the second member is in abutment with a first annular flange of the first member. A second radially inward projection of the second member is fitted in and welded to a vee on the first annular flange. Such weld acts as a seal for water-prooving the electric element. For preventing separation of weld due to repetition of radial expansion of electrical element upon current application thereto, a connecting means is provided between the first radially inward projection and the first annular flange.
