Claims

[Scope of utility model registration request]

a rack guide that holds a rack that engages with a pinion connected to a steering wheel side from a side opposite to the pinion so that the rack can move in the axial direction; a spring that biases the rack guide toward the rack; In a steering device equipped with a spring cap that adjusts the amount of compression of the spring, the rack guide and the spring cap are fitted to each other so as to be relatively rotatable, and the rack guide and the spring cap are mutually fitted between the rack guide and the spring cap. A steering device characterized in that a clearance is formed to allow relative movement in a direction approaching and a direction away from the steering device, and a locking portion is provided on each of the rack guide and the spring cap to prevent the clearance from expanding beyond a certain value. .
