In a state in which a ferruleis sandwiched and fixed between a ferrule receiving partand a ferrule pressing part, the ferruleis urged toward the ferrule receiving partside by an urging member. With this structure, without configuring such that the ferrule pressing part is screwed in the ferrule receiving part by rotating several times, the ferrulecan be pressed toward the ferrule receiving partside by a sufficient pressing force by the urging force of the urging member. Therefore, the attaching work of the columncan be performed more easily.

Column-attaching device and ferrule set

A ferrule containeris provided with a ferrule accommodating partand a first column guide part. A ferrule is accommodated in the ferrule accommodating part. The first column guide partguides a column so as to insert the column into the ferrule accommodated in the ferrule accommodating part. Guiding of the column by the first column guide partenables the column to be smoothly and reliably inserted into the ferrule accommodated in the ferrule accommodating part. Consequently, unlike a case in which an operator inserts a column while pinching a ferrule with hand, the work of inserting a column into a ferrule can easily be performed.

Ferrule container, and ferrule container containing ferrule

A ferruleis pressed by a pressing plate, and the ferruleis thereby sandwiched and fixed between a ferrule receiving partand ferrule pressing part. The pressing plateis displaced by a displacing mechanism, whereby the pressing plateis switched between a contacting state in which the pressing plateis in contact with the ferruleand a non-contacting state in which the pressing plateis not in contact with the ferruleand the ferrulecan pass thorough the inside of the ferrule pressing part. By displacement of the pressing plateto the non-contacting state, the ferrule pressing partcan be extracted from the ferruleside, and the ferrule pressing partcan therefore be removed from a columnin a state in which the ferruleis attached in a swaged fashion.
