Abstract
A workpiece support device including a base; a conducting rotary table that supports a workpiece and that is rotatable about a horizontal rotation axis; a motor that rotationally drives the rotary table; a collecting brush disposed on the base slidable on the outer circumferential surface of a conducting shaft fixed to the rotary table and extending along the rotation axis; a connection terminal that is electrically connected to the collecting brush and to which an external cable is connected; and a liquid-proof cover surrounding the collecting brush and the outer circumferential surface of the shaft. The liquid-proof cover includes an upper back-plate portion that is disposed at the same position as the rear end of the motor, and a lower back-plate portion located below the upper back-plate portion and forming a recess. The connection terminal penetrates through the lower back-plate portion and projects into the recess.
