STRUCTURE MAIN SILL MEMBER FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To prove structure of combination joint with other member to effectively utilize a material for regulation of an easy and firm main sill member. SOLUTION: The end parts of the other members 2 and 3 are fitted in between a pair of ribs 5 of which a part of a main sill member 1 consists. Registration during a work to join together the main sill member 1 and the other members 2 and 3 through the fit-in therebetween is simplified and ensured and a lateral deviation therebetween after joining is prevented from occurring. Further, even when bending occurs to the main sill member 1 before the material is joined with other members 2 and 3, by fitting the main sill member 1 in other member 2 having rigidity far higher than that of the main sill member 1, a work to straightly join the main sill member with the other members 2 or 3 is simply and rapidly executed.
