A deck board includes a board body arranged in a luggage area of a vehicle so as to be capable of being moved between an upper position and a lower position. The board body in the upper position separates the luggage area into upper and lower areas. The deck board further includes a front support portion that is rotatably connected to the front side of the board body so as to support the front side of the board body. Further included is a support pin that pivotally supports the fore end portion of the front support portion on the opposite side of the board body, so that a hinge portion can rotate. The deck board further includes a tension spring arranged to bias the front side of the board body toward the support pin.
