Claims

[Scope of utility model registration request]

a rotary shaft whose front end is connected to the front wheel steering link mechanism, extends rearward and rotates in accordance with the steering operation of the front wheels; and this rotary shaft is connected to an operating rod of the rear wheel steering link mechanism to rotate the rotary shaft. In a rear wheel steering device for a front and rear wheel steered vehicle, the coupling mechanism is provided with a coupling mechanism for steering a rear wheel by displacing the actuation rod in its axial direction in response to the actuation of the actuation rod. the second perpendicular to the axis of the rod
an input shaft rotatably assembled around an axis and rotated by the rotating shaft; and an input shaft rotatably assembled coaxially and rotatably with the input shaft to the actuating rod in a neutral position. an output shaft movable integrally with the actuating rod; a holder mounted to the housing between the two shafts so as to be tiltable about a third axis perpendicular to the second axis and parallel to the axis of the actuating rod; The input shaft is connected to the input shaft between the two shafts via a universal joint having a connection center at the intersection of the second and third axes, and is rotatably assembled to the holder and rotated by the input shaft. an intermediate shaft that is
a guide provided integrally with the output shaft between the intermediate shaft and the output shaft and extending in an arc shape with the intersection point as the center when the output shaft is in the neutral position; a pushing member that is integrally provided with the intermediate shaft between them and movably engages with the guide and rotates the guide when the intermediate shaft rotates; and a pushing member that is assembled to the housing and that rotates the holder. A rear wheel steering device for a front and rear wheel steered vehicle, comprising a drive means for rotating about the third axis.
