<p>A supporting device for display units enables height adjustment with ease and accuracy, and stably maintains the adjusted height while allowing a plurality of display units to be mounted thereon. The supporting device includes a stationary member (10), an elevation member (20) coupled to the stationary member (10) so as to be raised or lowered, a rack gear (41) secured to the stationary member (10), a pinion gear (42) installed to the elevation member (20) so as to engage with the rack gear (41), and a restriction unit (50) installed to the elevation member (20) to restrict or allow rotation of the pinion gear (42). The supporting device further comprises an upper-side supporting member (60) installed to an upper portion of the elevation member (20), first and second movable members (71,72) to move along a guide rail of the upper-side supporting member (60), and connecting devices (80) installed to the respective movable members to connect the display unit, respectively.</p> |
