Abstract: A vehicle entry-and-exit assistance device easily moves a board between a housed position and a using position. Embodiments include a board at an outer side of a seat adjacent to a door opening, the board rotatable between a horizontal posture and an orthogonal posture; a board support portion rotatable between a seat side-position and a flipped-up position; and a linking mechanism. The board pivots around an axis orthogonal to the vehicle width direction, and the support portion pivots around an axis extending in the vehicle width direction. The linking mechanism rotates the board to a vehicle-width-direction inner side with respect to the support portion to take the orthogonal posture when the support portion is rotated to the flipped-up position, and rotates the board to a vehicle-width-direction outer side with respect to the support portion to take the horizontal posture when the support portion is rotated to the seat side-position.
