Unless otherwise specified, tolerance: ± 0.3 (Unit: mm)


(Note1) A ground terminal is connected electrically to a shaft.

◆〈Shaft slot direction〉
There is a difference in the direction of the slot on the shaft between shorting and non-shorting type.
The location of the shaft of each type when their shafts are fully turned to CCW is shown in the chart below.
