械的零位置に調整される。 In the zero position adjustment device having such a configuration, the body portion 2b of the zero position adjustment shaft 2 is inserted into the hole 1 formed in the cover 1.
At the same time, the pin 2d is positioned in the hole 1c. Thereafter, by pushing the zero position adjustment shaft 2 into the hole, the zero position adjustment shaft is attached to the cover 1 with a snap fit by the action of the protrusion 2f formed on the body portion 2b. In this case, the pin 2d is engaged with a notch 3b formed in the zero position adjustment arm 3. By inserting a screwdriver or the like into the groove 2e and rotating the zero position adjustment shaft 2, this rotation is caused by the notch 3b of the zero position adjustment arm 3 via the pin 2d.
This zero position adjustment arm 3 is rotated about the boss stopper 4 by contacting the side surface of the same. This rotation is transmitted to the tension band via the tension spring 5, which causes the instrument movable part 9 to rotate, and the pointer 9b to be adjusted to a desired mechanical zero position.

Further, in the embodiment, the hole 1c is connected to the hole 1b, but as shown in FIG. 3C, the holes 1b and 1c may be provided independently. If it is desired to increase the rotation angle for zero position adjustment, it is preferable to configure as described above because if the fan-shaped hole 1c is connected to the hole 1b, snap-fitting will not be possible. Also, fan-shaped hole 1c
Instead of using it as a stopper, as shown in FIG. A hole 1d whose angle θ1 is smaller than the angle θ2 may be provided.

As explained above, in the conventional zero position adjustment device, the pin 2d of the zero position adjustment shaft 2, which is engaged with the zero position adjustment arm 3, is connected in series with the body part 2b for attaching this shaft 2 to the cover 1, that is, Although it was provided on the body part 2b,
This poses no problem if the distance between the cover 1 and the zero position adjustment arm 3 is sufficient. On the other hand, in the zero position adjustment device of the present invention, the pin 2d of the zero position adjustment shaft 2
Since it is provided in parallel with the body part 2b, that is, on the outside of the body part 2b, it is extremely suitable as a zero position adjustment device for a thin meter in which the distance between the cover 1 and the zero position adjustment arm 3 is narrow. Further, since the cover 1 is attached to the cover 1 by a snap-fit method, the number of parts is small, and furthermore, there is an advantage that only a slight modification is required to the zero position adjustment device of the conventional meter.
