PURPOSE: To raise the efficiency of drawing operation by a method in which drawing tools are attached to upper and lower frames facing each other, a support to be attached with a pull device is erectly set between the upper and lower frames, and when one end is drawn, the other end is held.

CONSTITUTION: A drawer device is made up of upper and lower drawing tools 5 and 6, a support 23, a pull device 32, and a coupler 18. The tools 5 and 6 are made up of couplers 7 and 10 and pullers 8 and 11. The tools 5 and 6 are attached to upper and lower frames 3 and 4 from the beginning, and the support 23 is erectly set by thrusting the screw 20 through the lower coupler 18 through a support piece 9 to the upper frame 3. When drawing the upper frame 3, hooks 33 and 34 are coupled to draw the frame 3 by the puller 32, and even for the lower frame 4, the hook 33 is coupled with the tool 6 to pull it in the same way. The drawing operation can thus be made by only one person.
