CLOSED CROSS-SECTIONAL PART, VEHICLE STRUCTURE PART, AND METHOD FOR IMPROVING IMPACT ABSORPTION PERFORMANCE

摘要

PROBLEM TO BE SOLVED: To easily improve impact absorption performance of a closed cross-sectional part by a simple means.;SOLUTION: A closed cross-sectional part includes: a structure 1 composed of a closed cross-sectional structure having one or more ridge line parts 5 extending along a longitudinal direction; and an adhesive 6 being adhered to an inner surface side of at least one of the ridge line parts 5 in the structure 1 so as to bury a corner part formed by the target ridge line part 5 in a continuous or intermittent manner along an extending direction of the ridge line part 5.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
