Box type structural body and vehicle end sill

摘要

There is provided a vehicle end sill or the like, in which lap joints formed by one side lap welding are not simply deformed or broken off. An end sill 1 is formed as a box type structural body which includes lap joints W1 which are formed by one side lap welding conducted only from the outer side. Edge portions 12a and 13a of face plates 12, 13 to be superposed on the surfaces 11a and 11b of the end member (intermediate member) 11 are formed as a zigzag shape. The end member has the longitudinal axis substantially perpendicular to the direction along which the load is adapted to be applied to the end sill 1. Lap welding (one side welding conducted only from the outer side) is conducted along the edge portion 12a and 13a of the zigzag shape. <IMAGE>
