ABSTRACT:
An indicating device with large graduations for a plane is installed at a combining section of a main base and a worktable of the plane, including a graduation ruler, a pointer and a rack. The graduation ruler formed as an arc is provided with graduations with number figures for readings. The upper end portion of the pointer faces exactly to the graduation ruler for pointing to one of the graduations. The pointer has gear teeth in its lower round edge for engaging with gear teeth located on one side of the rack. Therefore, a displacement the worktable moves relative to the main base can be clearly and easily read from the graduations of the graduation ruler.
