Electric power steering apparatus

摘要

The present invention relates to an electric power steering apparatus. According to the present invention, it is possible to provide an electric power steering apparatus configured to be capable of being assembled in a state in which the tension of a belt is correctly tuned without using a separate process of measuring the tension of the belt, to substantially reduce the number of steps at the time of assembling a motor housing and a rack housing and hence the manufacturing costs, and to reduce vibration and noise to provide a pleasant steering feeling to a driver.
