PURPOSE: To make it easy to grip with hand the upright frame of a rotary storing unit by placing plural storing bodies shaped in approximately rectangular frames between upper and lower endless rails to enable their free movement, joining neighboring storing bodies to each other with joining arms, and making the right and left upright frames of the storing bodies circular in their cross- sections.

CONSTITUTION: Plural storing bodies 4 shaped in approximately rectangular frames are placed between upper and lower endless rails 1 and 15 to enable their free movement. In addition, neighboring storing bodies are joined together with joining arms 5 and 22, and at least the right and left upright frames 4a of a storing body 4 are made ellipsoidal in their cross-sections. As a result, it not only becomes easy but also causes no undue apprehension to grip the upright frames of the storing bodies when moving the storing bodies.
