<P>PROBLEM TO BE SOLVED: To prevent a formation of a recessed part in an adhesive agent at a location between adjacent welded parts. <P>SOLUTION: In a joining structure 10 of a vehicle body member, a bent part 42 is formed on a base end part of an upper flange 30. In this bent part 42, a part 42B which overlaps the another one in an extending direction of a middle part between welded parts 36 and the upper flange 30 is structured so as to have a larger curvature radius than a part 42A which overlaps the another one in the extending direction of the upper flange 30 and each of the plurality of welded parts 36. And at the bent part 42, a flange width W1 between the base end part and a leading end part at the upper flange 30 is so changed that the central part between the plurality of welded parts 36 becomes narrower than each of the formed part of each of the plurality of welded parts 36. Accordingly, when spot welding, even if pressure of a spot gun 46 becomes lower at a location between adjacent welded parts 36, the adhesive agent 34 spreads between the base end part and the leading end part of a pair of the upper flanges 30 at a location between the adjacent welded parts 36. <P>COPYRIGHT: (C)2013,JPO&INPIT |
