A steering locking apparatus for a vehicle is designed in such a way that the rotation of a key rotor (7) located at an unlocking position to a locked position by the rotation of a key (5) is prevented by a restricting lever (16) and the prevention of the rotation of the key rotor (7) is removed by pressing a pressing button (19) so as to allow the key rotor (7) to be rotated to the locked position. In a state wherein the pressing of the pressing button (19) is prevented by operating an electromagnetic solenoid (24) under predetermined conditions and thereby engaging a stopper plate (26) supported by a plunger (25) of the electromagnetic solenoid (24) with the pressing button (19), the load applied to the pressing button (19) is received by a car body through the stopper plate (26). In consequence, no load is exerted on the plunger (25).
