<P>PROBLEM TO BE SOLVED: To improve the joint strength of a first member and a second member and prevent a part of a welded rib from flowing into a groove part formed in a joint area. <P>SOLUTION: Regulating ribs 30 and 30A which extend to an adjacent region properly spaced from the welded ribs 24 and 24A protruding from a second joint area 22 formed at the second member 20, are formed protruding at a specified position on a first joint area l6 formed at the first member l2. The tips of the regulating ribs 30 and 30A come into contact with the second joint area 22 in an appropriate timely manner after the start of vibratory welding and the spread of the welded ribs 24 and 24A which melt out into between both joint areas l6 and 22 is controlled by the regulating ribs 30 and 30A. Consequently, the welded ribs 24 and 24A are properly pressurized and the degree of compatibility between the welded ribs 24 and 24A and each of the joint areas l6 and 22 is increased. In addition, the regulating rib 30A prevents the molten welded rib 24A from flowing into the groove part 26. <P>COPYRIGHT: (C)2004,JPO |
