Abstract
A needle case and a yoke are respectively formed on their surfaces to be joined together with a key and a keyway which are so shaped as to provide a clearance for receiving a wedge of suitable shape. When driven into the clearance thus provided in the keyway between the needle case and the yoke fastened together, the wedge tightly holds them together in intimate contact with each other.
