ABSTRACT:
A handle apparatus has a rough movement handle and a fine movement handle for rotating an output shaft at leastwise two stages of rough and fine movements by rotationally operating these handles. The rough movement handle is constructed as a crank handle. The fine movement handle is provided in a position apart from a rotating center of the crank handle. A medium movement handle may be provided coaxially with the fine movement handle. It is therefore possible to provide the inexpensive handle apparatus capable of increasing a driving torque of the rough movement handle, shifting the fine movement handle to an arbitrary position, making an installation thereof easier and reducing the number of parts required.
