Claims

[Claims for Utility Model Registration] The rotational force of the drive motor is transmitted to a driven member via a gear train, and the pointer is rotationally driven in conjunction with the movement of the driven member, and the pointer is rotated at the final stage of the gear train. , a potentiometer whose rotation range is regulated by a stopper is provided, the rotation range of the pointer is regulated by the potentiometer, and the driven member is provided with a potentiometer whose rotation range is regulated by a stopper.
In an indicating instrument that applies a biasing force to remove bumps in the gear train, a stopper is formed between a pair of gears in the gear train near the rotating shaft of the drive motor, and the stopper and the pointer rotate. An indicating instrument characterized in that a gear train between a stopper of a potentiometer located at an extreme position on a direction side has teeth packed toward an extreme position of a pointer.
