CONSTITUTION: An electric power steering device comprises a worm shaft(10), a worm wheel(20), a housing(30), a motor unit(40), and a supporting part. A worm gear(11) is comprised in the worm shaft. The worm wheel is rotated with the worm gear and rotates a steering shaft. The housing covers the worm shaft and the worm wheel. The motor unit is coupled with the housing and rotates the worm shaft. The supporting part is coupled with the housing and supports the end portion of the worm shaft by using magnetic force. |
