PROBLEM TO BE SOLVED: To make a seam allowance dimension variable with good workability.SOLUTION: A guide member 30 in a rectangular parallelepiped shape is rotatably attached to a sewing machine body 12 via a rotation shaft 34, and flat four faces FS1 to FS4 of the guide member 30 can be sequentially brought into contact with an end of a skin piece by rotation of the guide member 30 with the rotation shaft 34 as the center of rotation. The shortest distance between one face of the four faces and the center of rotation is made different from the shortest distance between other faces of the four faces different from the one face and the center of rotation. |
