It is a molded part that has an L-shaped protruding part at one end and a double fold back and a screw hole at the other end. There is a pressing portion having a spring property, which has a plurality of concave portions corresponding to the thickness of the control cord in the c portion. As shown in FIG. 5, the other cord receiving plate 22 is a rust-proof metal flat plate having a round hole or a rectangular hole at one end and a screw at the other end. There is a hole engraved with a thread to stop the.

Then, as shown in FIG. 6, the absorption refrigerator has
