Abstract:
A steering locking device for restraining an operation of a steering wheel at a time of locking, comprising:a collar surrounding a steering shaft which is rotated integrally with the steering wheel, the collar being provided with an opening, an annular clearance being formed between an outer periphery of the steering shaft and an inner periphery of the collar; a spacer press-fitted in the annular clearance and being formable into a circular arc shape surrounding the steering shaft, the spacer being formed of a woundable member which is woundable around the steering shaft from an outside of the collar through the opening of the collar, the spacer being elastically deformable so as to increase or decrease a diameter of the circular arc formed by the spacer; a locking device main body fixed to a fixing member; and a locking member supported on the locking device main body and being displaceable to a locked position for preventing the collar from being rotated, and a locking released position, wherein a relative rotation between the steering shaft and the collar is restrained by the spacer in a case where a torque applied to the steering shaft is not more than a predetermined torque when the collar is prevented from being rotated by the locking member at the locked position, and wherein the spacer is connected to the steering shaft so as to be integrally rotatable, and is pressed against the inner periphery of the collar by such an elastic restoring force that the spacer attempts to return to a free state.
