Tonneau cover unit

A tonneau cover unit, comprising:

• a tonneau cover that covers a luggage floor which is formed on a rear side within a vehicle;
• a board that is fitted to an end portion of the tonneau cover, and that is provided with an engaging portion;
• and
• a rail along which the engaging portion of the board slides in a longitudinal direction of the vehicle,
• wherein the rail has:
• a first engaged portion in which the engaging portion is engaged and that locks the board with the board kept substantially parallel to the luggage floor when the engaging portion is engaged in the first engaged portion;
• and
• a second engaged portion which is formed at a position that deviates from the first engaged portion in the longitudinal direction of the vehicle, and in which the engaging portion is engaged, and that locks the board with the board kept substantially upright at a predetermined angle with respect to the luggage floor when the engaging portion is engaged in the second engaged portion,
• wherein an orientation of the board when the engaging portion is engaged in the first engaged portion differs from an orientation of the board when the engaging portion is engaged in the second engaged portion,
• the engaging portion is a projection piece that projects from an end portion of the board toward a vehicle inner wall face in which the rail is formed,
• the rail is a groove in which the projection piece is placed and along which the projection piece slides;
• and
• the second engaged portion includes:
• a step portion that is formed by grooving a side face of the groove, at a middle portion of the rail, by one step in a height direction of the vehicle, and that has a size sufficiently large for a width of the projection piece in a direction substantially parallel to the board;
• and
• a longitudinal groove that is formed by further grooving a part of the step portion, and that has a width which substantially corresponds to a width of the projection piece in a thickness direction of the board.
