A linear guide device comprises a guide base on which a runner assembly is movably guided in the direction of a longitudinal axis of the guide base. The runner assembly is driven along the longitudinal axis by a drive spindle that is in threaded engagement with a drive nut on the runner assembly. For additional support of the drive spindle there is a pair of spindle support units, one unit on either side of the runner assembly. A traction rope formed as an endless loop connects the two spindle support units and is reversed over a pulley at the ends of the guide base. The traction rope moves freely past the runner assembly such that the spindle support units are displaceable along the longitudinal axis by abutment of the runner assembly against one of the spindle support units, the other spindle support unit being towed along the guide base in following relation by the traction rope.
