MOTOR ACTUATOR HAVING CONCENTRICITY MAINTAINING STRUCTURE

摘要

PURPOSE: A motor actuator having a concentricity maintenance structure is provided to improve productivity by removing additional assembling processes for maintaining concentricity. CONSTITUTION: A worm wheel(200) is driven by engaging with a worm gear(W). A housing accommodates a motor and the worm wheel. A concentricity maintenance member(400) is installed at the housing. The concentricity maintenance member is combined with a motor shaft(110). The concentricity maintenance member maintains the concentricity of the motor shaft.
