  • Patent number: 7740213
    Abstract: In the liquid crystal panel stand, the rotating shaft (13) pierces the fixed member (12), and a fixing portion is provided for fixing the rotating shaft to block its rotation around the axial center. The holding member (14) having a protrusion (14b) protruding from one side surface is formed into a thin configuration for applying the urging force in the direction where the protrusion (14b) protrudes so as to be fixed to the fixed member (12) to apply the pressing force in the direction where the protrusion (14b) protrudes with the force in substantially parallel with the rotating shaft (13). The movable member (11) includes a plurality of holding holes (15, 16) as openings through which the protrusion (14b) of the holding member (14) fixed to the fixed member (12) is inserted to be engaged therewith when the movable member (11) is rotated along the rotating shaft (13).
