Provided is an electric power-assisted steering (EPAS) apparatus including a gear housing in which a nut coupler coupled with a ball nut through a bearing is formed and an accommodation portion is formed in an internal circumferential surface of the nut coupler, and a lock screw configured to have an external circumferential surface on which a screw portion is formed, coupled to the nut coupler, and supports the bearing, and to have a loosening preventer formed to protrude toward the accommodation portion after the screw portion is coupled to the nut coupler.

An airbag device includes: an airbag body that is configured to deploy toward a front side of a driver; and a control unit that is configured to deploy the airbag body using a first deployment method when a central axis of a rim portion of a steering member of a vehicle is in a first state and a deployment condition is satisfied and deploy the airbag body using a second deployment method in a second state when an inclination angle of the central axis in relation to the central axis in the first state exceeds a threshold and the deployment condition is satisfied.

A steer-by-wire steering device includes a steering shaft 7; a rotation-restricting member A including an annular main cylindrical portion 1 mounted on the steering shaft 7 and at least one main ridge portion 2 formed on an outer periphery of the main cylindrical portion 1; an engagement member 6 configured to move in proximity to and away from the rotation-restricting member A; and a cushioning member B. The engagement member 6 and the at least one main ridge portion 2 are configured to come in contact with each other through the cushioning member B in conjunction with rotation of the steering shaft 7.

In an electric steering lock device for saddle-ride type vehicle, a casing movably supports a lock pin and a slider. The lock pin is linearly movable between a lock position and an unlock position. The slider is movable in a direction identical to a movement direction of the lock pin. The casing houses an elastic member that is interposed between the lock pin and the slider, and an electric motor that provides a power that drives the slider. The electric steering lock device for saddle-ride type vehicle avoids being large-sized and reliably detects a position of the lock pin. A casing 18 movably supports a first interlocking member 72 and a second interlocking member 73. The first interlocking member 72 moves in a direction identical to a lock pin 19 by interlocking with the lock pin 19. The second interlocking member 73 moves in a direction orthogonal to the movement direction of the lock pin 19 and the first interlocking member 72 by interlocking with the first interlocking member 72. A switch 74 that detects a position of the second interlocking member 73 is mounted on the casing 18.

A system for a vehicle includes a gear and a plate fixed to the gear. The gear is driving by a motor for providing relative rotation between a steering wheel and steering shaft of the vehicle in an adaptive front steering system. The system includes a solenoid including a coil and a pin moveable relative to the coil to engage the plate based on a signal. A sensor is configured to detect a change in current through the coil associated with initial movement of the pin relative to the coil. The system includes a controller programmed to change the duty cycle signal in response to the change in current to slow movement of the pin to reduce or eliminate a clicking noise associated with the pin seating in an extended position or retracted position.

A steering lock device includes a motor configured to rotate a motor shaft, a worm attached to the motor shaft of the motor, a main gear configured to rotate along with rotation of the worm, a cam member integrally provided with the main gear, and a rod including an insertion and extraction portion. The insertion and extraction portion is configured to be inserted into and extracted from an opening provided on a steering shaft side in accordance with an operation of the cam member along with rotation of the main gear. At least a part of at least one member of the worm and the insertion and extraction portion is configured to be accommodated in a circumferential region of the main gear when the main gear is viewed in a plan view along a rotation axis direction of the main gear.
