Abstract:
1. A method for engaging a pair of polycrystalline silicon rods by using a coupling member having both end parts larger than the width of a slit being received into an engaging groove, in order to engage a pair of polycrystalline silicon rod, wherein the silicon rods have a structure for hanging of silicon rods to each other end-to-end, wherein the engaging groove is formed on both end face of the rods facing to each other, the engaging groove being defined by the slit having a narrow width and an inner space larger than the width of the slit, said slit being open on an end face of the rod and said inner space being open on a side face of the rod for receiving the coupling member having both end portions, said coupling member received into the engaging groove being passed through the open slit to become a state bridging over both rods, and both end portions of the coupling member fitted into the said inner space being engaged with the slit to become the state stopping the passing through, and the silicon rods being passed through the coupling member.
