PURPOSE:To prevent the oscillation of a pointer almost without using designed space by regulating the rest position of a pointer wheel depending on magnetic interaction between a magnetic material integral formed with the wheel and a magnetic material fixed on a non-movable section of a movement. CONSTITUTION:As a positioning magnet 1 is magnetized in the direction of the arrow, an attraction force is generated between magnetic teeth 2 made of a soft magnetic material. The positioning magnet is fixed on a wheel train carrier 8 through a rotary bush 5 and with the position of a convex thereof 1 fixed, the magnetic teeth 2 can be positioned governed by the convex within the rnage of a backlask of the pointer wheel 8. This can prevent the oscillation of the pointer using little designed space. |
