Claims (1)

[Scope of Claim for Utility Model Registration] (1) A front wheel steering mechanism that steers the front wheels according to the rotation of a steering wheel; a pair of cables that respectively transmit rearward steering amounts in the respective directions; and a pair of cables that are housed in a housing and are connected to rear ends of the pair of cables and that control the rear wheels in accordance with the steering amounts that are respectively transmitted via the cables. In a four-wheel steering system for a vehicle equipped with a rear wheel steering mechanism for steering, a pair of cables are formed in a tubular shape and fixed to the vehicle body at a predetermined location, and each accommodates the pair of cables along the internal axis direction. A casing is provided, and is screwed onto each rear end outer periphery of the pair of casings on each inner periphery, and screwed onto each inner periphery of each entry port of the pair of cables in the housing on each outer periphery. A four-wheel steering system for a vehicle, characterized in that each rear end of the pair of casings is assembled to the housing via a pair of nut members having different pitches or screw directions on the inner circumference and each outer circumference. (2) A front wheel steering mechanism that steers the front wheels in response to rotation of a steering wheel; and a front wheel steering mechanism that is connected to the front wheel steering mechanism at each front end and extends rearward to steer the left and right steering amount of the front wheels rearward, respectively. Four wheels of a vehicle, comprising a pair of cables for transmitting information, and a rear wheel steering mechanism that is connected to each rear end of the pair of cables and that steers the rear wheels according to the amount of steering that is transmitted via the cables. In the steering device, a pair of casings are formed in a tubular shape and are fixed to a vehicle body at a predetermined location, and each accommodates the pair of cables along an internal axial direction; A four-wheel steering device for a vehicle, comprising a bracket that holds a pair of casings and is movably fixed to a vehicle body.
