Claims

[Scope of utility model registration request]

A connecting member whose front end is connected to the front wheel steering link mechanism, extends rearward, and is operated in response to steering operation of the front wheels, and this connecting member is connected to an operating rod of the rear wheel steering link mechanism to operate the connecting member. In a rear wheel steering device for a front and rear wheel steered vehicle, the rear wheel steering device is provided with a coupling mechanism for steering a rear wheel by displacing the operating rod in its axial direction in accordance with the movement of the operating rod. a carrier assembled to be rotatable about a second axis perpendicular to the axial direction of the housing; and a driving means assembled to the housing to rotate the carrier about the second axis, the carrier being in a fixed state. a first coupling body attached to the carrier so as to be rotatable about a third axis passing through the second axis and parallel to the axis of the actuating rod; and a first coupling body disposed between the carrier and the actuating rod and attached to the housing. The actuating rod has an arcuate tooth portion centered on the fourth axis that is assembled to be rotatable about a fourth axis perpendicular to the second axis and the third axis, and that engages with a rack provided on the actuating rod on one side. a sector gear, a second connecting body assembled to the sector gear in a neutral state so as to be rotatable about the third axis, and connected to the first connecting body so as to be rotatable about the second axis; The first connecting body is connected to the distal end of an arm provided on the first connecting body, and is also connected to the rear end of the connecting member, so that the connecting part with the connecting member can be moved forward or backward along the second axis. 1. A rear wheel steering device for a front and rear wheel steered vehicle, comprising a link that rotates one connected body about its rotation axis.
