<p>PROBLEM TO BE SOLVED: To assemble and exchange a work supporting plate with excellent workability and to obtain a necessary suitable attaching strength for the work supporting plate. SOLUTION: In a work table device, in which work supporting plates 6 are bent and deformed in corrugation because of an alternate pitch deviation in the slits of adjacent supporting crosspieces 4a-4b and in which the supporting plates 6 are fixed on the crosspieces 4a-4e by a restoring force from the bend, every other crosspieces 4a-4e, i.e., crosspieces 4b, 4d are fixedly provided in a displaceable manner in the extending direction of the crosspieces 4a-4e against a frame 1 by tightening nuts 13 which are each screwed onto screw threads 12 of movable blocks, enabling the pitch deviation of the slits of the adjacent crosspieces to be selectively set to zero or a prescribed value.</p> |
