Title
(EN) HOLLOW MEMBER
Abstract
(EN)

Energy absorption at the time of load input is improved with high mass efficiency.

A hollow member includes: a hollow metal member having a bending induction portion in a portion thereof in a longitudinal direction; and a resin material which is disposed in close contact with the metal member on both sides of the bending induction portion in the longitudinal direction, and is disposed in at least a part of a range of less than ⅚ of a cross-sectional height of the metal member from an end portion of the bending induction portion toward an outside in the longitudinal, in which an amount of the resin material per length in the longitudinal direction is larger on the outside of the bending induction portion than on an inside of the bending induction portion.
