A balancer is installed with a frame directed substantially vertically. When an electric motor is energized, a ball screw shaft is rotated about its own axis, displacing a table mechanism in a substantially vertical direction. Simultaneously, a cylinder in the frame is operated to move a piston substantially vertically. At this time, magnets on the piston and magnets in the table mechanism are magnetically attracted to each other, so that the table mechanism is pulled in the same direction as the piston. Consequently, the burden on the electric motor which is loaded by the weight of a workpiece carried by the table mechanism is lessened.
