Claims

[Scope of Claim for Utility Model Registration] A support bush that swingably supports a suspension arm, and an inner pipe through which a support shaft extending in the longitudinal direction of the vehicle body is inserted, and which is inserted into the inner pipe. , an outer pipe that forms a circumferential gap between the inner pipe and the outer circumference of the inner pipe.
a rubber layer connecting the inner pipe and the outer pipe and separating the circumferential gap into a circumferential gap on the outer side of the vehicle body and a circumferential gap on the inner side of the vehicle body; An orifice is formed that communicates the outer peripheral gap with the inner peripheral gap of the vehicle body, and the outer end of the vehicle body is brought closer to the outer pipe than the inner end of the vehicle body. It consists of an orifice block inserted into the inner pipe, and liquid sealed in each of the gaps and the orifice, and the spring constant on the outside of the car body is larger than that on the inside of the car body. A support bush for a suspension arm.
