Patent ID: 8839900

Claim:
A structure of a roll-rod for a subframe filled with a hydro liquid therein; comprising: a bracket bar having a front bush mounted at one end thereof; an inner pipe including: a cylindrical pipe, one end of which is mounted on the other end of the bracket bar; and a supporting plate joined with the cylindrical pipe; an endplate joined to the other end of the cylindrical pipe, wherein the endplate is spaced with from the cylindrical pipe; an outer pipe enclosing the inner pipe between the bracket bar and the endplate and including an extension part; where the supporting plate is disposed with a gap in the extension part having a curved shape such that an inner diameter of the extension part is shaped to be larger than an outer diameter of supporting plate while the inner pipe is inserted in the extension part; an insulator forming a front liquid chamber and a rear liquid chamber with the supporting plate in a front and a rear of the supporting plate in a longitudinal direction of the cylindrical pipe while the insulator is mounted between the cylindrical pipe and the outer pipe in a radial direction of the cylindrical pipe so as to receive the hydro-liquid therein; and a housing into which the outer pipe is inserted and fixedly joined and configured to be fixed to the subframe, wherein the supporting plate is movable relatively to the outer pipe such that the gap between the supporting plate and the extension part varies while the insulator is elastically transformed according to movement of the bracket bar and the endplate.
