  • Publication number: 20200039565
    Abstract: A steering apparatus 200 comprises an outer column 10 provided with a guide groove portion 25, an inner column 11 provided with a stopper 300, and a steering shaft 3 on which a steering wheel 101 is attached. An adjustable range of a telescopic position of the steering wheel 101 is restricted by the stopper 300 being contacted with a portion, at a rear side of the vehicle, of the guide groove portion 25. The stopper 300 includes a stopper body 331 and a fastening and connecting means 332 for fixing the stopper body 331 to the inner column 11. The stopper body 331 and the inner column 11 are formed, respectively, with through-holes 331c and 11a communicated with each other, through which the fastening and connecting means 332 is inserted. With this configuration, a steering apparatus in which the stopper can be easily attached to the inner column is provided.
