The invention provides a device for preventing lateral displacement for stabilizers, which is simple in construction and easy to manufacture and which is free from thermal degradation. A device for preventing lateral displacement for stabilizers, characterized by comprising a flat plate which includes a first end and a second end, an upper surface contacting a stabilizer, and a lower surface lying opposite to the upper surface, and cut-in steps formed by concaving the upper surface of the first end and the lower surface of the second end, wherein the flat plate is wound along its plate surface around the outer periphery of the stabilizer at a predetermined position thereon and is tightened, and the cut-in steps overlap each other and the opposite ends are fixed at the overlap. |
