を設けたことを特徴とするミシンの上糸調子台。 A pair of tension discs and a coil spring are sequentially inserted into the support shaft, and an adjustment nut is screwed into a threaded portion formed at one end of the support shaft, and one end of the coil spring is pressed into contact with the adjustment nut. By moving the adjustment nut back and forth in the axial direction, the coil spring is expanded and contracted to change the pressure contact force between the two tension discs, thereby adjusting the tension of the upper thread wound between the two tension discs. In the needle thread tension stand of the sewing machine, a pressure-sensitive conductive rubber is attached to the spindle so as to be deformed in accordance with the pressure applied to the tension plate by the expansion and contraction of the coil spring, and the pressure-sensitive conductive rubber is An upper thread tension stand for a sewing machine, characterized in that it is provided with a means for extracting the degree of deformation as an electric signal.
