Abstract

PURPOSE: To offer a lapping device which assures accurate positioning adjustment by eliminating backlash between a worm wheel and worm.
CONSTITUTION: An outer cylinder 1 holding a chucking shaft 2 with rotary freedom with a bearing interposed, is supported by a framing member 4 mounted on the fixed base 3 with the aid of a key 5 which assures mobile possibility only in the axial direction. This outer cylinder 1 is designed with possibility to rotate with the aid of the main worm wheel when a handle shaft 6 for fine adjustment is rotated. A backplate 9 is mounted solidly to this main worm wheel 7 with a cylindrical spacer 8 interposed, and between this backplate and the main worm wheel 7 an auxiliary worm wheel 11 shall be provided in such a way that it can rotate together with the main worm wheel 7. Two or more springs 13 are interposed between this auxiliary worm wheel 11 and backplate 9. Thus the backlash between a worm and a worm wheel can be prevented.
