Has been formed.

With such a mode, when the operator grips the knob portion 30a, the partition plate 150 can be prevented from being an obstacle, facilitating the attachment/detachment operation of the stopper member 30 and preventing the stopper member 30 from falling. And work efficiency can be improved.

Further, as shown in FIG. 14, the main body portion 153 of the partition plate 150 is formed so that the plate thickness becomes thinner toward the pedestal 13 (−Z axis side) (T5<T4).

According to such an aspect, when the main body 153 is manufactured, the main body 153 can be easily taken out from the mold, so that the manufacturing efficiency can be improved.

Further, by making the plate thickness of the lower end portion of the partition plate 150 (the end portion of the partition plate 150 on the side of the pedestal 13) thin, the lower end portion of the partition plate 150 when the test terminal cover 140 is mounted on the test terminal 12. Since the contact between the metal terminal 14 and the metal terminal 14 can be reduced, the workability of mounting the test terminal cover 140 can be improved.

On the other hand, the alternative measuring instrument terminal partition plate 152 of the partition plate 150 is formed such that the plate thickness thereof becomes thinner toward the upper end portion (+Z axis side) of the partition plate 150 (T6<T4).

According to such an aspect, as in the case of the main body portion 153, it is possible to easily take out the alternative measuring instrument terminal partition plate 152 from the form when manufacturing the alternative measuring instrument terminal partition plate 152, so that the manufacturing efficiency can be improved. Becomes

Of course, when the entire partition plate 150 including the main body portion 153 of the partition plate 150 and the terminal partition plate 152 for the alternative weighing device is manufactured by one mold, for example, the entire partition plate 150 has a lower end (-Z axis). It may be formed such that the plate thickness becomes thinner toward the side) (T5<T4<T6).
