Claims

[Scope of utility model registration request]

A housing assembled to the vehicle body; an input member assembled to the housing and connected to the front wheel steering device so as to transmit power; and an input member assembled to the housing and connected to the rear wheel steering device so as to transmit power. and an output member assembled in the housing to connect the input member and the output member, and driven by a drive device assembled in the housing to be in a non-transmission state, an in-phase transmission state, or a reverse-phase transmission state. the input member and the output member are connected so that power cannot be transmitted when the connection mechanism is in a non-transmission state, and the rear wheel steering device is connected to the front wheels when the connection mechanism is in an in-phase transmission state. The input member and the output member are connected so as to be able to transmit power so as to operate in the same phase as the front wheel steering device, and further, when the connection mechanism is in a reverse phase transmission state, the rear wheel steering device is in reverse phase with the front wheel steering device. In a variable steering ratio device for a front and rear wheel steered vehicle, in which the input member and the output member are connected to enable power transmission for operation, the variable steering ratio device is driven by the drive device and interlocks with the input member and the output member. A positioning hole opening toward the housing is provided in one component of the movable connecting mechanism, and the positioning hole opens when the connecting mechanism is in a non-transmission state and the input member and the output member are in a neutral state. Front and rear wheels characterized in that a mounting hole coaxial with the same positioning hole is provided in a part of the opposing housing, and a positioning pin whose tip can be inserted into the positioning hole can be attached to this mounting hole. Steering ratio variable device for steered vehicles.
