<p>The present invention is to provide a device for a chamber case of a brake chamber of a vehicle, which can contribute to vehicle weight reduction by applying a plastic resin material to the chamber case and which can increase the rigidity and durability of the chamber case by forming a reinforcing rib in the chamber case and reinforcing the weak portion of the chamber case by adjusting the thickness of the chamber case. To achieve the purpose, the device according to the present invention is formed in a structure to enclose a power spring and a piston. And, the thickness of the upper end part of the chamber case is formed thicker than the thickness of the side part thereof in order to reinforce the strength of the chamber case.</p> |
