An upper thread tension display device, characterized in that one of the class classifications of thread thickness and cloth thickness is displayed on the movable scale section and the other is displayed on the fixed scale section. (2) In contrast to the divided display of the fixed scale section, the movable scale section is an upper thread tension device displayed on a graduated belt driven by a dial that moves in a direction across the divided display. Upper thread tension display device according to range 1. (3) Corresponding to the divided display on the fixed scale section, the movable scale section divides and displays the integrated scale width, and the movable scale section is an upper thread tension device that moves parallel to the divided display on the fixed scale section. An upper thread tension display device according to claim 1 of the utility model registration claim. (4) Claims 2 and 3 of the utility model registration claim characterized in that the display of the divided fixed scale is an optical means that indicates the fixed scale part by an electric circuit connected to a push button on which the scale is displayed. Upper thread tension display device as described. (5) Claims (2) and 3 of the Utility Model Registration characterized in that the display of the divided fixed scale is indicated by an arrow provided at the tip of a lever connected to the selection dial on which the scale is displayed. Upper thread tension display device as described in Section 1. (6) An upper thread tension device that adjusts the upper thread tension by biasing the upper thread tension spring using a cam part, and the adjustment of the thread tension tension gradient is performed by a transmission lever of an intermediate transmitter between the cam part and the upper thread tension spring. The upper thread tension display device according to claim 2, wherein the center of rotation is constituted by an eccentric pin. (7) An upper thread tension device that adjusts the upper thread tension by biasing the upper thread tension spring using a cam portion, and has an arcuate groove for rotating around the dial axis to adjust the thread tension gradient. The upper thread tension display device according to claim 2, characterized in that the upper thread tension display device comprises a cam portion having a cam portion and a locking means for the cam. (8) Either the thread thickness or the fabric thickness is displayed on the indicator part of the upper thread tension device, and the other is displayed on the selection dial, so that the upper thread tension indicator part is displayed on the selection dial.
