Abstract
An electric power steering system comprising an upper bracket, a steering column, a steering shaft provided rotatably within the steering column, a tilt mechanism comprising a tilt clamp which tightly fastens the steering column between tightening plate portions of the upper bracket and a tilt pivot which oscillates the steering column, an electric assist unit provided at a lower end of the steering column, and a lower bracket fixed to the vehicle body at an opposite side of the electric assist unit to the steering column to rotatably support a pivot shaft of the tile pivot. A housing of the electric assist unit is brought into engagement with a pivot shaft of the tilt pivot in such a manner as to be allowed to move loosely, so that the steering column is allowed to oscillate about the pivot shaft, and a column rotation restricting portion is provided between the lower bracket and the housing.
