1. A vehicle steering apparatus comprising:
a telescopic mechanism that can move a steering column in a front and rear direction of a vehicle; a tilt mechanism that can tilt the steering column in a vertical direction of the vehicle; a driving mechanism that adjusts and transmits an output torque of a driving motor to a telescopic screw shaft that drives the telescopic mechanism and to a tilt screw shaft that drives the tilt mechanism provided in parallel with the telescopic screw shaft; and a switching mechanism that has a first clutch mechanism which connects and disconnects the driving mechanism and the tilt screw shaft, a second clutch mechanism which connects and disconnects the driving mechanism and the telescopic screw shaft, and a switching motor that switches a clutch mechanism between the first clutch mechanism and the second clutch mechanism, wherein the first clutch mechanism and the second clutch mechanism of the switching mechanism has a first clutch member and a second clutch member, respectively, which mutually move in an axial direction and transmit a rotational force when either the tilt screw shaft or the telescopic screw shaft is connected to the driving mechanism, and when the switching motor moves one of the first clutch member and the second clutch member in a predetermined direction, one of the first clutch mechanism and the second clutch mechanism is put in a connection state, the other of the first clutch member and the second clutch member moves in a direction opposite to the predetermined direction, and the other of the first clutch mechanism and the second clutch mechanism is put in a disconnection state. |
