To provide a fastening structure for a vehicle which can perform a fastening work of a second nut without using a tool for preventing the corotation of a first nut.SOLUTION: A fastening structure for a vehicle comprises: a bolt arranged at a first member of a vehicle body; a third member loosely fit to the bolt in a state where a rotation around an axis of the bolt is constricted by a second member of the vehicle body; a first nut screwed with the bolt to regulate the movement of the third member to one side of the bolt in an axial direction; a second nut screwed to the bolt at one side of the bolt in the axial direction rather than the first nut; and a fourth member interposed between the first nut and the second nut. The fourth member has a washer part sandwiched between the first nut and the second nut, and an abutment part abutting on the third member. The third member abuts on the abutment part to regulate the rotation of the fourth member around the axis of the bolt.SELECTED DRAWING: Figure 2

    【課題】第1ナットの供回りを防止するための工具を用いることなく、第2ナットの締め付け作業を行うことができる、車両用締結構造を提供する。【解決手段】車両用締結構造は、車体の第1部材に設けられたボルトと、車体の第2部材にボルトの軸周りの回転を拘束された状態で、ボルトに遊嵌された第3部材と、ボルトに螺合して、ボルトの軸方向一側への第3部材の移動を規制する第1ナットと、第1ナットよりもボルトの軸方向一側においてボルトに螺合した第2ナットと、第1ナットと第2ナットとの間に介挿された第4部材と、を備える。第4部材は、第1ナットと第2ナットとに挟持される座金部と、第3部材に当接する当接部とを有し、第3部材は、当接部に当接し第4部材のボルトの軸周りの回転を規制する。【選択図】図2
