Abstract
A hinge structure for a flat visual display device comprising: a pivotal plate connected to the flat visual display device; a fixing plate connected to a supporting portion for supporting the flat visual display device; a rotational shaft inserted to vertical planes of the pivotal plate and the fixing plate, for rotation of the flat visual display device in one degree of freedom; a frictional member which is formed on an outer periphery of the rotational shaft for enclosing the rotational shaft, and whose both ends have a frictional member tightening plane of a planar shape on which a second inserting hole is formed; and a tightening member inserted to the second inserting hole, for tightening the frictional member tightening plane, thereby tightening the rotational shaft by means of the frictional member, and generating strong breaking force accordingly.
