Claims

[Claim for Utility Model Registration] A permanent magnet fixed to one end of a flexible shaft that transmits the rotation of an automobile's drive system, and a permanent magnet that is rotatably placed opposite the permanent magnet, and generates a rotational moment as the permanent magnet rotates. A helical spring is used to adjust the reaction torque of the helical spring. A speedometer with an indicator adjustment mechanism, characterized by being provided with an adjustment lever that changes the position of the fixed end of a spring.
