<p>PROBLEM TO BE SOLVED: To set and maintain tension of a belt in a proper range more easily in an electric power steering device.SOLUTION: By an elastic force of a coil spring 35, distance between a partition part 24 and a pressing part 26, and a distance between a driven pulley 42 and a driving pulley 41, and furthermore, tension of a belt 33 are determined. Therefore, for example, even when looseness of a bolt or elongation of the belt 33 occur, the tension of the belt 33 is kept in a proper range by the elastic force of the coil spring 35. Also, the tension of the belt 33 generates through the elastic force of the coil spring 35 just by assembling both housings 21 and 25, setting of the tension of the belt 33 to an initial value becomes easy.</p> |
