To achieve rigidity of a colum part corresponding to a type of a collision body by a small and simple structure.SOLUTION: A rigidity varying structure of a vehicle column part includes a rigidity changing body 20 and a control device. The rigidity changing body 20 is arranged in a hollow part 17 of a front pillar 13, and selectively chooses a first mode of increasing rigidity of the front pillar 13 and a second mode of reducing the rigidity of the front pillar 13 than the first mode by actuating in the hollow part 17. When a collision of a collision body with a vehicle body is predicted or detected, the control device controls operation of the rigidity changing body 20 to make the rigidity changing body 20 take the first mode or the second mode to achieve the rigidity of the front pillar 13 corresponding to a type of the collision body.SELECTED DRAWING: Figure 2

    【課題】小型かつ簡単な構成で支柱部の剛性を、衝突体の種類に応じた剛性にする。【解決手段】車両用支柱部の剛性可変構造は、剛性変更体20及び制御装置を備える。剛性変更体20は、フロントピラー13の中空部17に配置され、かつ同中空部17で作動することにより、フロントピラー13の剛性を高める第1態様と、第1態様よりもフロントピラー13の剛性を低下させる第2態様とを選択的に採る。制御装置は、衝突体の車体に対する衝突が予測又は検出された場合、剛性変更体20の作動を制御することにより、同剛性変更体20を、第1態様及び第2態様のうち、フロントピラー13の剛性を衝突体の種類に応じた剛性にするための態様にする。【選択図】図2
