PURPOSE: A cube for developing intelligence is provided to enable a stable operation by preventing a dropping out during a movement and/or a rotation with integrally forming a fastening protrusion which is hanged in a hanging groove on the contact surface of a guider of each moving member which is moved and/or rotated. CONSTITUTION: A cube for developing intelligence integrally comprises 8 fan shaped sectors according to a guiding hole in the circumference of the sphere. 2 fan shaped sectors are connected with a screw. A first, a second, a third, and a fourth guider (22, 32, 42, 52) are fitted respectively in the guiding hole between the fan shaped sector. Fastening protrusions (23, 24) are respectively formed in both side end parts of the first guider of a first moving member (21) in order to be inserted in the hanging groove of the guiding hole or a hanging groove (33) of a second moving member (31). Fastening protrusions (53, 54) are respectively formed in both side end parts of the fourth guider of a fourth moving member (51) in order to be inserted in the hanging groove of the guiding hole or a hanging groove (43) of a third moving member. The second moving member and the third moving member are contacted to each other. |
