The hook(12) which becomes the rotational center when open/close of the inlet grill and the projector(11) for fixation on the inlet grill(2) and on the front grill(1), the hinge bracket part(13) that supported the hook formed on the inlet grill and the elastic hook part(10) that the projector gets hooked is formed and the break projector(17) which elastically operates by being pushed by the hook is formed when open/closing of the inlet grill and the spring board(16) at the hinge bracket part. When open the inlet grill, the hook spins and positions between the two facing break projectors and at this point, since the thickness of hook is thicker than the distance between the break projector, passes through between the break projector as pushing it away by the artificial pushing force and regains the elasticity of spring board. When the hook passes through completely, the open state of the inlet grill is kept since the break projector returns to its original position by the restorability of spring board. |
