<P>PROBLEM TO BE SOLVED: To provide a vehicular frame structure in which an increase in weight of a frame is suppressed and furthermore the bending strength of the frame is increased. <P>SOLUTION: The frame 1 includes: a first face part 11 to which a force in the compression direction is applied; a second face part 21 to which a force in the tensile direction is applied, both of the forces being applied when a load is applied to the frame from the outside; and third face parts 12, 22 which are positioned on both sides of the frame and between the first face part 11 and second face part 21 of the frame 1 and which form corner parts 1a, 1b between the first face part 11 and second face part 21, respectively. The corner parts 1a formed between the first face part 11 and third face parts 12, 22 are formed in curved line parts 1c, and parts adjacent to the curved line parts 1c on both-side third face parts 12, 22 are formed in straight line parts 12a, and the frame 1 includes a first connection part 30 connecting boundary parts 12b of the curved line parts 1c on both-side third face parts 12, 22 and the straight line parts 12a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
