Abstract
A telescopic module, which may be incorporated in a desk or a chair to elevate or lower a work surface, includes a first tube, a second tube, a holder, and a plurality of rollers. The first tube has a passageway. The second tube is received in the passageway of the first tube for reciprocation. The holder is mounted on the first tube. The rollers are pivoted on the holder to rest against the second tube or the first tube, or both to touch an inner side of the first tube and an outer side of the second tube to be turned when the second tube is moving. The rollers may reduce the friction between the first and the second tubes when the second tube is moving.
