みを阻害しない鉄筋篭を提供することを目的とする。According to the conventional reinforcing bar cage, since the connecting side portion is movable with respect to the main body, the lateral length of the reinforcing bar cage can be changed. Therefore, even if the spacing between both reinforcing bar cages is not as designed due to installation errors in both reinforcing bar cages that were installed earlier, manufacturing errors in each reinforcing bar cage, etc., it is possible to place the reinforcing bar cages between both reinforcing bar cages. . However, on the other hand, the poured concrete does not easily wrap around the overlapping portion of the main body and the connecting side portion, which has a high density, and special measures are required to solve this problem. Further, the relative position (lap length) of the main body and the connecting side portion in the solidified concrete is determined by the magnitude of the adhesion between the reinforcing bars of the reinforcing bar cage and the solidified concrete;
Since it is determined by the magnitude of shear resistance of the solidified concrete, there is a limit to how short the lap length between the main body and the connecting side portions can be. SUMMARY OF THE INVENTION An object of the present invention is to provide a reinforcing bar cage whose length dimension is variable and which does not inhibit the movement of poured concrete.

Conversely, when subjected to compressive forces, both plate members 34, 36 press the concrete in opposite directions. As a result, the external force is transmitted to the main body 24 and the connecting side 26, and from the reinforcing bar cage 16 to the other reinforcing bar cages 12, 14.
