A steering wheel lock device comprising a key rotor housed in a rotor case and adapted to be turned between a lock position and an operative position by a key inserted into said key rotor, said key rotor being allowed to move in its axial direction by pressing operation of the key; a cam rotated in association with the key rotor so as to move the lock member; a regulating member having a distal end portion; a regulating projection formed on the outer peripheral surface of the key rotor in such a manner that when the key rotor is turned from the lock position to the operative position, the distal end portion of the regulating member passes past the regulating projection relative thereto, thereby allowing rotation of the key rotor toward the operative position, and when the key rotor is turned from the operative position to the lock position with the key rotor kept in a non-pressed condition, the regulating projection is engaged with the distal end portion of the regulating member, thereby preventing the key rotor from turning to the lock position; and a bypass passage provided in the outer peripheral surface of said key rotor so as to bypass said regulating projection.
