クラスタ。[Claims for Utility Model Registration] A spider body detachably connected to a control rod drive shaft, a plurality of vanes extending radially from a side surface of the spider body, and a finger attached to the tip of each vane. , a control rod cluster comprising: a control rod having a male threaded portion at its upper end that is screwed into a female threaded portion formed in each of the fingers; the finger extends coaxially with the female threaded portion; and a through hole in which at least one groove is formed on the inner surface of the upper end thereof; and the control rod has an extension shaft extending coaxially from the male threaded portion and having a thin-walled cylindrical portion at the tip thereof; After the female threaded portion of the finger and the male threaded portion of the control rod are screwed together, a portion of the cylindrical portion facing the groove is deformed and fitted into the groove, thereby forming the finger and the male threaded portion of the control rod. A control rod cluster configured to connect with the control rods.
