PURPOSE:To correct easily an error generated between a pointer and an indicating scale by fixing a unit body to only a base plate, and also forming it so as to be turnable coaxially with a pointer shaft. CONSTITUTION:In case a bracket 20 is moved in the same direction as an error correcting direction of a pointer in a circular arc-shaped hole part 22, by the same angle portion of an error theta between the pointer 9 and an indicating scale marked on a dial 5, a unit body 17a turns centering around a shaft 19, and at the same time, a pointer shaft 8 also rotates, and the pointer 9 moves to a correct indicating position of the scale. Thereafter, the unit body 17a is clamped and fixed to a base plate 2 by a nut 24 and a screw 23, and the pointer 9 is held at a correct indicating position of the scale. In this way, an error generated between the pointer and the indicating scale can be corrected easily and quickly. |
