Claims

[Claims for Utility Model Registration] (1) A pedal sensor that converts the movement of a lever to which pedal movement is transmitted into an electrical signal through a connecting rod whose one end is connected to the pedal, wherein the connecting rod is connected to the pedal. An industrial sewing machine control having a lever fixed to the lever by a screw and nut having a head structure having a plurality of flat side surfaces, and provided with a concave portion or a convex portion that matches at least one surface of the flat side surface portions of the screw head. Pedal sensor connection device of the device. (2) In a pedal sensor that converts the movement of a lever into an electrical signal, the movement of the pedal is transmitted through a connecting rod whose one end is connected to the pedal, and the connecting rod has a washer and a plurality of flat side parts attached to the lever. An industrial sewing machine fixed by a screw and a nut having a head structure, the washer having a rotation prevention structure that matches at least one side of a flat side surface of the head of the screw and at the same time matches at least one adjacent side of a lever. Pedal sensor connection device for control device.
