To provide a vehicular step capable of preventing damage of a relay member over a cross member due to breakage of a mounting leg portion of a mounting bracket upon side collision of a vehicle.SOLUTION: Of a mounting bracket 33, a mounting leg portion 35a on an inner side in a longitudinal direction of a side step 23 is extended to an inner side in a longitudinal direction of the side step 23 than a relay member part 9a over a cross member 15. Near a fastening portion 39 on a tip end side, a stress concentration portion 45 that breaks the mounting leg portion 35a from a part near the fastening portion when a side collision load of a predetermined value or more is inputted to the side step 23 is formed. If the side step 23 is sharply folded from a center side due to side collision, the mounting leg portion 35a is broken from the part near the fastening portion while inclining, and a breakage surface Y of the mounting leg portion 35a facing the vehicle body 2 side first is released to a side part of the relay member part 9a over the cross member 15.SELECTED DRAWING: Figure 6
【課題】本発明は、車両の側突時、取付ブラケットの取付脚部の破断を要因としたクロスメンバを跨る中継部材の損傷が防げる車両のステップ装置を提供する。【解決手段】本発明は、取付ブラケット33のうち、サイドステップ23の長手方向内側の取付脚部35aを、クロスメンバ15を跨る中継部材部分9aよりもサイドステップ23の長手方向内側へ延出させ、かつ先端側の締結部39の近傍にはサイドステップ23へ所定以上の側突負荷が入力されると、締結部近傍から取付脚部35aを破断させる応力集中部45を形成し、側突によりサイドステップ23が中央側から鋭角的に折れ曲がると、取付脚部35aが傾きながら締結部近傍から破断され、車体2側へ最先に向かう取付脚部35aの破断面Yが,クロスメンバ15を跨る中継部材部分9aの側方へ逃げるようにした。【選択図】図6
