PROBLEM TO BE SOLVED: To enable the tension of a plurality of conductors to be measured individually with a simple configuration in a transmission belt manufacturing process in which a plurality of tension core wires are arranged in parallel and are buried. SOLUTION: A tension measuring device of a conductor for belts comprises a plurality of measurement pulleys 50, 50, and the like so that each of conductors 3, 3, and the like on the way to a belt forming mold from a delivery roll can be suspended. A plurality of support rods 47, 47, and the like are movably provided so that each of the measurement pulleys 50, 50, and the like can be supported rotatably. The support rods 47 can be energized to one side by a tension spring 51. A displacement gauge 52 for measuring the displacement of the support rods 47 travels so that it can measure the displacement of the plurality of support rods 47 by a drive motor 54, or the like. The displacement of the support rods 47 measured by the displacement gauge 52 is input to a sequencer and is converted to the value of tension in the conductor 3. The position of the displacement gauge 52 is discriminated by a rotary encoder mounted to the drive motor 54. COPYRIGHT: (C)2007,JPO&INPIT
