PROBLEM TO BE SOLVED: To provide a vehicular frame in which a welding length between joining ends is sufficiently ensured without complicating a shape of the joining ends. SOLUTION: A frame (2) has a first frame member (25a) and a second frame member (35a), and square cylindrical joining ends (41, 46) of the first and second frame members are butted and welded to each other. The joining ends of the first and second frame members have first to fourth edges (43a-43d, 47a-47d) which are continuous in the peripheral direction, respectively. The first to fourth edges are inclined even when the joining ends are viewed in either direction along the radial direction. COPYRIGHT: (C)2006,JPO&NCIPI
