Locking of the steering shaft is prevented.

When the shift lever is shifted to the parking position in the state shown in FIG. 6 (the state in which the key rotor 13 is turned to the operating position and the shift lever is at a position other than the parking position), the interlocking member 26 moves to the arrow B. Moves in the opposite direction to be located at the first position shown in FIG. In this state, the locking recess 27 of the interlocking member 26 is in a state corresponding to the locking projection 32 of the regulating member 28, and the movement of the regulating member 28 in the direction opposite to the arrow C is allowed. Has become.

In the state shown in FIG. 5, when the key rotor 13 is rotated from the operating position toward the “LOCK” position, the second cam surface 20 of the second cam projection 17 is moved to the second projection of the regulating member 28. By pressing 30, the regulating member 28 is moved in the direction opposite to the arrow C (the regulating position direction). Therefore, when the shift lever is shifted to the parking position in a state where the key rotor 13 is in the operating position, the key rotor 13 can be turned to the “LOCK” position.

When the key rotor 13 is rotated to the "LOCK" position, the regulating member 28 is moved to the regulating position as shown in FIG. Is restricted from moving from the first position to the second position. Further, by rotating the key rotor 13 to the “LOCK” position, the key can be pulled out from the key rotor 13 and the stelling shaft can be locked by the lock bar.

According to the first embodiment, the regulating member 2
2 is moved from the restriction position shown in FIG. 2 to the restriction release position shown in FIGS. 5 and 6 using the first cam surface 19 of the cam member 14, and is moved from the restriction release position to the restriction position. This is performed on the second cam surface 20 of the cam member 14. Then, when assembling the interlocking member 26 with the key rotor 13 in the operating position (“ACC” position), the regulating member 28 moves to the regulation release position allowing the movement of the interlocking member 26 by the first cam surface 19. (See FIGS. 5 and 6),
