Title
(EN) HOLLOW MEMBER
(ZH) 中空的部件
Abstract
(EN)
A hollow member implements, with high mass efficiency,the absorption of energy at the time of a load input. This hollow member is provided with: a hollow metal member which has a bending induction part in a portion thereof in the longitudinal direction; and resin members which are disposed on both sides, in the longitudinal direction, of the bending induction part so as to be in close contact withthe metal member, and which are disposed within at least a portion of the range of less than five sixths of the cross sectional height of the metal member so as to each extend from an end of the bending induction part toward the outside in the longitudinal direction, wherein the amount of the resin members on the outer side of the bending induction part is larger, per longitudinal length, than that of the resin members on the inner side of the bending induction part.
