The invention provided a sewing machine, improved to automatically switch the sewing machine to the thickness of cloth. This sewing machine includes: a housing having a base plate; a top arm; and a strut for integrating the base plate with the top arm. A metallic presser presses a cloth piece near a stitch forming position. The metallic presser driven by a movable rod is capable of moving between the lift position for releasing the cloth piece and the pressing position for the cloth piece to be pressed. When the metallic presser moves between these positions, the distance of at least one movable rod part from a reference structure fixed to the housing stably changes. The position sensor detects the position of the metallic presser in the pressing position. A control system makes signal connection thereto. The system sets an adjustment variable for the sewing machine depending upon the output value of the position sensor. As a result, the obtained sewing machine automatically performs switching to the thickness of variable cloth piece.
