PROBLEM TO BE SOLVED: To surely prevent the axial movement of a shaft support member by tightly sticking the end portion of a fixing member to the base of a recessed part formed in the shaft support member, pushing the shaft support member in a direction orthogonal to the axial direction by the fixing member, and surely fixing the shaft support member to a sewing machine frame. SOLUTION: A thread tension bracket 17 is formed with a recessed part 21 formed of a wall face 23 being parallel to a second axial direction, and a bottom base 24 orthogonal to the wall face 23 in the second axial direction, and includes a screw set 20 having a first shaft part 25 mounted on the sewing machine frame to regulate a movement in the second axial direction, and a second shaft part 26 formed with a side 29 along the second axial direction, which faces the wall face 23 of the recessed part 21. In a state where the set screw 20 is mounted on the sewing machine frame, the end portion 28 of the second shaft part 26 presses the bottom 24 of the recessed part 21. COPYRIGHT: (C)2008,JPO&INPIT
