To provide a getting-on and getting-off assist device for a vehicle capable of achieving both suppression of a bottoming feeling when a board is expanded and operability for a vehicle occupant.SOLUTION: A getting-on and getting-off assist device for a vehicle includes: a board 22 rotatable between an expanded first posture P1 and a folded second posture P2; a support frame 24 for supporting the board 22 rotatably; an attaching part 26; a rotation shaft part 30 for rotating the support frame 24 in a back and forth direction of the vehicle; and a first shock absorber 52 and a second shock absorber 54 configured so as to make reaction force act on the rotation of the support frame 24 by the rotation shaft part 30. The first and second shock absorbers 52 and 54 are configured so that the reaction force of only the first shock absorber 52 acts in less than a predetermined first stroke of all strokes when the board 22 is expanded from the second posture to the first posture, and the reaction force of both the first shock absorber 52 and the second shock absorber 54 acts in the predetermined first stroke or more.SELECTED DRAWING: Figure 5

    【課題】ボード展開時の底付き感の抑制と、乗員の操作性とを両立することができる車両用乗降補助装置を提供する。【解決手段】展開された第1姿勢P1と、折りたたまれた第2姿勢P2との間で回動可能なボード22と、ボード22を回動可能に支持する支持フレーム24と、取付部26と、支持フレーム24を車両前後方向に回動させる回動軸部30と、回動軸部30による支持フレーム24の回動に対して反力を作用させるよう構成された第1緩衝装置52および第2緩衝装置54とを備え、第1および第2緩衝装置52、54は、ボード22が第2姿勢から第1姿勢へと展開するときの全ストロークのうち、所定の第1ストローク未満では、第1緩衝装置52のみの反力が作用し、所定の第1ストローク以上では、第1緩衝装置52および第2緩衝装置54の両方の反力が作用するよう構成されている。【選択図】図5
