To provide a wall surface sticking device capable of positioning a plurality of suction pads according to tile sizes so that they do not come to joints even on a surface of a tiled wall of various tile sizes and having deep joints, and capable of obtaining a sticking force of 50 to 60 kg or more which is necessary to cancel a work reaction force, and to provide a cage provided with the wall surface sticking device.

A wall surface sticking device (1) includes a central section (3) having a central shaft (2), a plurality of rotation rods (6) whose longitudinal centers are pivotally supported to the central shaft (2) of the central section (3), a plurality of suction pads (4) respectively provided to both sides of the rotation rods (6) so as to be movable, and a link mechanism (5) which movably connects the plurality of suction pads (4). The link mechanism (5) links and moves the plurality of suction pads (4) along the longitudinal direction of the rotation rods (6), so that each of the plurality of suction pads (4) is translationally moved in a longitudinal or lateral direction. Consequently distances of the suction pads (4) can be enlarged or shrunk.
