PROBLEM TO BE SOLVED: To provide a steering device which extends the life of a disc spring elastically supporting a bearing of a ball screw mechanism.SOLUTION: A steering device includes: a ball screw mechanism 8 which applies an axial force to a rack shaft of a vehicle on the basis of rotation of a nut 80; and a bearing 20 which supports the nut 80 so that the nut 80 rotates relative to the housing 10. The steering device includes: a plate 31 which is disposed spaced away from the bearing 20 in a rack shaft axial direction ZA; and a disc spring 32 disposed between the bearing 20 and the plate 31. The plate 31 contacts with the housing 10 in the rack shaft axial direction ZA. The disc spring 32 elastically supports the nut 80 in the rack shaft axial direction ZA through the bearing 20. One side surface 31c of the plate 31 which faces the disc spring 32 is formed into a taper shape so as to intersect with a rack shaft radial direction ZB. |
