Publication number: 20230143959Abstract: The steering device includes a steering shaft, a steering column, a bracket, and a fastening mechanism. The steering column includes a lower column and an upper column. The upper column includes a clamp, a cylindrical part, a pair of protrusions, and a reinforcement rib that extends across an outer peripheral surface of the clamp and an outer surface of one of the protrusions. The clamp includes a continuous clamp positioned near the cylindrical part and a spaced clamp spaced apart from the cylindrical part. The protrusions include a continuous protrusion that protrudes from the continuous clamp, and a spaced protrusion that protrudes from the spaced clamp. The reinforcement rib linearly extends from the spaced protrusion toward the continuous clamp.Type: ApplicationFiled: March 25, 2021Publication date: May 11, 2023Applicant: NSK LTD.Inventors: Tomohiro IKUTA, Yoshiyuki SATO, Suguru SUGISHITA, Hirotaka SHIMIZU
