Abstract:
Disclosed is a leveling motor, which removes a gap from a threaded portion converting a rotating force of the leveling motor into an axial feeding force to minimize a movement error and enable a leveling operation to be precisely controlled, and includes a housing, a shaft axially moving in the housing and having on an outer circumference thereof a threaded portion, a threaded pipe provided on an outer circumference of the shaft and having on an inner circumference thereof a grooved portion that corresponds to the threaded portion, and an elastic member supplying an upward elastic force to the shaft, whereby the threaded portion axially comes into close contact with the grooved portion by the elastic force of the elastic member.
