PROBLEM TO BE SOLVED: To provide an eyelet hole linking sewing machine with which smooth needle shogging motion is carried out without the exertion of undue load on the respective members of a needle shogging mechanism and a sewing machine spindle. SOLUTION: This eyelet hole linking sewing machine 1 has a needle shogging mechanism 3 including a needle shogging oscillation body 106 which vertically moves back and forth cooperatively with the sewing machine spindle 44, a needlebar guiding member 60 into which a needle bar 20 is inserted and a needle shogging yoke 200 which consists of a connecting collar 203 having connecting pins 204 and 204 inserted onto an upper part 60b of the needlebar guiding member 60, a supporting shaft 201 inserted to the needle shogging oscillation body 106 and fork parts 200a and 200a for supporting the connecting pins 204 and 204. The surfaces 200b and 200c parallel to each other are formed at the fork parts 200a and 200a so as to face one above the other and the connecting pins 204 and 204 are grasped across angular barrels 210 and 210 so as to be oscillatable along the two surfaces between the two surface facing one above the other.
