1. An entry-and-exit assistance device for a vehicle, the entry-and-exit assistance device being provided on a vehicle-width-direction outer side of a seat adjacent to a door opening of the vehicle, the entry-and-exit assistance device comprising:
a board that is rotatable between a horizontal posture in which the board is substantially horizontal and an orthogonal posture in which the board is substantially orthogonal to a vehicle width direction in a vehicle cabin;
a support portion that is a support portion of the board provided between the board and a vehicle body and is rotatable between a seat side-portion position on a vehicle-width-direction outer side of the seat and a flipped-up position in which the support portion is flipped up to a vehicle front side or a vehicle rear side of the seat side-portion position; and
a linking mechanism that is provided between the board and the vehicle body and links rotation of the support portion with rotation of the board, wherein
the board is pivotally supported by the support portion to be rotatable around an axis line orthogonal to the vehicle width direction and is supported by the support portion to maintain the horizontal posture when the board is in the horizontal posture,
the support portion is pivotally supported by the vehicle body to be rotatable around an axis line extending in the vehicle width direction, and
the linking mechanism is configured to cause the board to be rotated to a vehicle-width-direction inner side with respect to the support portion and take the orthogonal posture when the support portion is rotated from the seat side-portion position to the flipped-up position, and to cause the board to be rotated to a vehicle-width-direction outer side with respect to the support portion and take the horizontal posture when the support portion is rotated from the flipped-up position to the seat side-portion position.
