<p>An actuator portion 8 provided separately from an operating portion includes a lock member 13 for locking a steering shaft 9, a motor 18, and a lock control mechanism 34. The lock control mechanism 34 has a driven body 21 rotated by the motor 18 through a gear mechanism 43, a cam member 20 for moving the lock member 13, and an unlock spring member 27 constituted by a torsion coiled spring and disposed between the driven body 21 and the cam member 20. When the motor 18 is subjected to an unlocking operation in the condition that handle torque acts on the lock member 13, the spring force of the unlock spring member 27 is accumulated while the unlock spring member 27 absorbs the rotational displacement of the driven body 21.</p> |
