Claims

[Claims for Utility Model Registration] A main shaft 2 rotatably supported by a sewing machine arm 1 and operatively connected to a motor 3; A needle bar 10 is moved up and down, and a needle 13 is removably attached to the lower end of the needle bar 10.
a lower shaft 16 rotatably supported by the sewing machine bed 15 and rotated or rotated in conjunction with the rotation of the main shaft; The hook 20 is provided with a tip 21 for catching a thread ring, and a fixing screw 24 is provided for fixing the hook and the lower shaft so that the attachment position of the hook to the lower shaft can be adjusted. An adjustment gauge for a sewing machine that forms stitches by working, and the adjustment gauge is removably fixed to the needle bar 10 and has a notch that can be engaged with the tip of the hook point 21. 35, and the notch has an axis substantially perpendicular to the axial direction of the lower shaft for moving and positioning the tip 21 in the axial direction of the lower shaft with the fixing screw 24 loosened. A direction abutment surface 36 is formed, and a thread wheel capture direction abutment surface 37 substantially parallel to the axial direction of the lower shaft is formed for rotating and positioning the tip 21 in the thread wheel capture direction. An adjustment gauge for a sewing machine, characterized by:
