ABSTRACT:
A supported body, such as a display panel or liquid crystal panel, is revolvably supported by a support via a revolution shaft and secured at an arbitrary revolution angle by a lock device. The lock device includes a torsion spring having a free end and a fixed end, into which the revolution shaft is inserted in an intimately contacting state, a holding member provided to the support or supported body so as to hold the revolution shaft rotatably and having an engaging part engaged with the fixed end of the torsion spring, and a stopper member secured to the revolution shaft and abutting the free end of the torsion spring for preventing coming-off of the fixed end of the torsion spring from the engaging part. In addition, an interlocked rotating member is disposed rotatably on the revolution shaft between the stopper member and the free end of the torsion spring so as to abut to and rotate together with the free end of the torsion spring when the supported body is revolved in a reverse direction relative to the winding direction of the torsion spring. The torsion spring and the stopper member can be replaced with a pair of torsion springs disposed so as to sandwich the interlocked rotating member which is typically ring-shaped.
