Abstract: An inclination angle-adjustable supporting device to be used for a display by attaching it to a display apparatus or a display wall. This supporting device comprises an outer cylindrical member having a hollow housing portion at its proximal end portion, a basic rod member housed in the housing portion of the outer cylindrical member in such a manner that the distal end portion thereof is pivoted on the outer cylindrical member so as to allow the outer cylindrical member to incline, and an adjustment screw adapted to be inserted through the bottom surface of the outer cylindrical member and to allow the distal end portion thereof to push on the bottom surface of the basic rod member, thereby to perform the adjustment of the inclination angle of the outer cylindrical member. The basic rod member may be housed in the outer cylindrical member through an adaptor.
