Claims

[Claims for Utility Model Registration] A rear wheel steering rod that is supported by a housing so as to be movable in the direction of an axis extending left and right and rotatable around the axis, and that steers the rear wheels by moving in the left and right direction; a support body disposed within the housing so as to be rotatable around an axis extending longitudinally and rotated when the front wheels are steered; an annular drive member having a radially extending through hole with a concave spherical inner circumferential surface formed at a predetermined position, and for moving the rear wheel steering rod in the left-right direction by rotation of the support; and a rear wheel steering rod. A pin with a circular cross section is fixedly provided on the rear wheel steering rod so as to be perpendicular to the axis of the steering rod, and the pin is fitted into the pin so as to be able to slide in the axial direction of the rod, and is fitted into the through hole of the annular drive member. A rear wheel steering device for a four-wheel steering vehicle comprising a spherical bush fitted so as to be tiltable in any direction, wherein a spring receiver is attached to the spherical bush so as to protrude toward the free end of the pin; A compression coil spring is arranged between the spring receiver and the pin, and the spring receiver has an occluded shape when viewed from the axial direction of the pin and is configured to open radially outward by its own elastic force. A substantially annular spring portion and a radially outward groove that is integrally provided on the edge of the spring portion on the spherical bushing side and that is fitted into an annular groove formed on the inner peripheral surface of the hole in the spherical bushing. a bent part;
A spring receiving part that is integrally provided so as to extend inward in the radial direction and continue with the remaining part of the spring part, excluding the part facing the missing circular part, at the edge opposite to the bent part of the spring part. A rear wheel steering device for a four-wheel steering vehicle comprising:
