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, an elevation member coupled to the stationary member so as to be raised or lowered, a rack gear secured to the stationary member, a pinion gear installed to the elevation member so as to engage with the rack gear, and a restriction unit installed to the elevation member to restrict or allow rotation of the pinion gear. The supporting device further comprises an upper-side supporting member installed to an upper portion of the elevation member, first and second movable members to move along a guide rail of the upper-side supporting member, and connecting devices installed to the respective movable members to connect the display unit, respectively. |
