RADIATION PANEL DEVICE

摘要

Among outward path-side extension parts and returning path-side extension parts protruding from panels, an outward path-side extension part and a returning path-side extension part installed at the same side with respect to a rotary shaft are connected. That is, the outward path-side extension part and returning path-side extension part extracted via extraction tube sections are connected without variation in distance before and after swing of a panel.
