The needle head 7a of the sewing needle 7 is inserted in the needle insertion hole 12c of the needle holding portion 12. The contact element 14 is inserted in the through hole 13a formed in the through hole portion 13. The operation screw 15, which is formed from a component separated from the contact element 14, is rotated and screwed into the through hole 13a. The operation screw 15 presses against the contact element 14 without rotating the contact element 14, thereby pressingly fixing the sewing needle 7 in place. Therefore, the sewing needle 7 will not tilt or moved downward by rotation of the operation screw 15. In this way, the sewing needle 7 can be simply and accurately positioned.
