A handlebars locking apparatus (10) for locking and unlocking of the handlebars (5) on the basis of a code collation is provided. A collation ECU (20) releases a restriction of a rotor (12) latched by a latch (17) by driving a solenoid (15) if an ignition switch is turned OFF while a lock pin (11) is retracted. After releasing the restriction, rotation of the rotor (12) is restricted by the latch (17) and a code collation with a code stored in a portable key (30) is carried out if a lock pin (11) is in a protrusion state after the release of the restriction and the protrusion state is detected by a lock side switch (27). If the code collation is correctly carried out, the protrusion of the lock pin is maintained to lock the handlebars (5). If the code collation is not correctly completed, the restriction of the rotor (12) is released so as to be returned into an unlocked state.
