PROBLEM TO BE SOLVED: To provide a portable slope which can be compactly folded in the travelling direction of a wheelchair as well as improve the traveling stability of the wheelchair by reducing the amount of downward deflection of the travelling surface of the portable slope in the expanded state.SOLUTION: A portable slope includes: a slope body 2 which serves as a travelling surface 4 of a wheelchair in an expanded state Y1; and an expansion maintaining metal fitting 3 for maintaining the expanded state Y1. The slope body 2 is formed from at least one slope connection body 5 having first connection means 7 for connecting a plurality of slope pieces 6, into which the slope connection body is divided in the travelling direction of a wheelchair, so as to be folded on the mountain fold side. The expansion maintaining metal fitting 3 includes: a first and second metal fittings 10 and 11 attached to the outside surface of the slope pieces 6 adjacent to each other in the travelling direction; a connection shaft 12 for connecting the first and second metal fittings 10 and 11 so as to be bent around a lateral axis line j; and a stopper part 13 for preventing the bending of the slope pieces to the valley fold side in the expanded state Y1. |
