Abstract:
A resin component comprising:a first synthetic resin molded body (61); and a second synthetic resin molded body (62) coupled with said first synthetic resin molded body (61) by a vibration welding, wherein said first resin molded body (61) includes a joint area (63) which is provided at its edge portion where said first molded body (61) is joined to said second molded body (62), a first regulating projection (64) which is provided from an outermost edge of said joint area toward said second molded body (62), and a first guide surface (65) connecting an internal side surface of said first regulating projection (64) to said joint area (63), and wherein said second resin molded body (62) includes a welding projection (66) which is projected toward said first molded body (61) so as to be welded at a distal end thereof to said joint area (63) of said first molded body (61) and is provided at its edge portion where said second molded body (62) is jointed to said first molded body (61), a second regulating projection (67) which is projected from an outermost edge of said second molded body (62) toward said first molded body (61) so as to closely confront said first regulating projection (64) after a vibration welding operation between said welding projection (66) and said joint area (63) is completed, and a second guide surface (68) connecting an external side surface of said welding projection (66) to an internal side surface of said second regulating projection (67), wherein said first guide surface (65) is formed into a curve shape to guide a burr produced to project toward said first regulating projection (64) as a result of vibration welding of said welding projection (66) to said joint area (63) toward said internal side surface of said second regulating projection (67) along said internal side surface of said first regulating projection (64), and said second guide surface (68) is curved and located in confront with said first guide surface (65) so as to guide the burr guide from said internal side surface of said first regulating projection (64) to said internal side surface of said second regulating projection (67) toward said external side surface of said welding projection (66).
