  • the end of the convex portion 1b of the end surface 1a of the first part with which the horn 4 abuts is welded, the end is accommodated in the step portion 3, and the end of the convex portion 1b Is prevented from being pushed out to the outer periphery of the component, resulting in a resin-molded product with good appearance. That is, in the welding process, when the convex portion 1b of the end surface 1a of the first component 1 is formed flush with the end surface 1a, the end of the convex portion 1b is welded to the step portion 3 provided on the periphery. Does not jump out.
