PURPOSE:To perform a spacer inserting work very easily and surely by turning side frames and intermediate frames with rear ends of intermediate frames as fulcrums to open gap parts after intermediate frames are positioned between two side frames. CONSTITUTION:Intermediate frames 5 between which a shield plate 8 is interposed are inserted between two side frames 1a and 1b and are positioned mutually, and edges 51 and 52 are formed in rear ends of intermediate frames 5 in this state. Screw rods 15 and 16 for depressing the shield plate 8 are engaged with an arm 14. When the screw rod 16 is loosened to depress the screw rod 15, one intermediate frame 5 and the upper side frame 1a are turned with the edge part 52 in the rear end of the intermediate frame as a fulcrum to open a gap G2, and a jig 17 is moved to insert a spacer 19. In case that a gap part G1 is opened, the screw rod 16 is depressed. Consequently, the spacer inserting work is performed very easily and surely. |
