PROBLEM TO BE SOLVED: To provide a vehicle door frame which achieves high welding strength of an inner member to an outer member.SOLUTION: An inner joint part 55 has an inner inside surface 56, an inner outside surface 57 positioned closer to the outer side of a door frame than the inner inside surface 56; and an inner side surface 58 which connects the inner inside surface 56 with the inner outside surface 57. An outer joint part 35 has: an outer inside surface 36 which faces the inner inside surface 56 through a gap; and an outer side surface 37 facing the inner side surface 58. In a welding portion W, an inner cutout 59 is provided at an outer edge of the inner joint part 55, and a welding passage WP which communicates from the outer side to the inner side of the door frame is formed between the inner side surface 58 and the outer side surface 37. A welding bead WB which is formed so as to bury at least the welding passage WP adheres to the inner outside surface 57, the inner side surface 58, the inner inside surface 56, the outer side surface 37, and the outer inside surface 36.SELECTED DRAWING: Figure 4
【課題】インナ部材のアウタ部材に対する溶接強度の高い車両用のドアフレームを提供する。【解決手段】インナ接合部55は、インナ内面56と、インナ内面56よりもドアフレームの外方に位置するインナ外面57と、インナ内面56とインナ外面57とを接続するインナ側面58とを有し、アウタ接合部35は、インナ内面56に隙間を介して向かい合うアウタ内面36と、インナ側面58に向かい合うアウタ側面37と、を有し、溶接個所Wにおいて、インナ接合部55の外縁にインナ切欠き59が設けられてインナ側面58とアウタ側面37との間にドアフレームの外方から内方へ連通する溶接通路WPが形成されており、少なくとも溶接通路WPを埋めるように形成された溶接ビードWBが、インナ外面57、インナ側面58、インナ内面56、アウタ側面37およびアウタ内面36に付着している。【選択図】図4
