置。A worm nut that reciprocates within the gear housing in conjunction with the operation of a steering wheel, and a sector that is integrally formed with a sector shaft that is pivotally supported by the gear housing and that engages with the worm nut and rotates together with the sector shaft. By screwing and adjusting the adjustment screw connected to one end of this sector shaft with respect to the gear housing cover side, the sector is displaced along the axial direction of the shaft, thereby reducing the preload between this sector and the worm nut. In a ball screw type steering mechanism that performs adjustment, the amount of displacement of the sector shaft required to obtain an appropriate preload between the sector and warm dead in the axial direction between the sector shaft and the adjustment screw is equivalent to A preload adjustment device that provides a gap and interposes an elastic body between the sector shaft and the adjustment screw to maintain this gap in a free state.
