Abstract: A housing extends in an axial direction of a rack shaft connected to a pinion shaft so as to cover at least the rack shaft, and has an end portion on which a cover member is fitted to cover the end portion. The housing includes a holding portion that has an inner side sinking in a radial direction of the housing, and holds the cover member, and a plurality of convex portions that protrude in the radial direction of the housing, and are circumferentially disposed on a downstream side of the holding portion in a fit-in direction of the cover member, while separating from the holding portion by a predetermined distance in the fit-in direction.
