<P>PROBLEM TO BE SOLVED: To provide a structure that allows a lid to be easily mounted/removed with little force in a short time, with respect to a structure wherein the opening portion of a cabinet is sealed with a removable lid. <P>SOLUTION: A gasket 4 is mounted on the surface of one side of a lid plate 3 having a profile larger than the profile of the opening portion 2. A locking material 6 is pivotally rotatably supported on the side of the lid plate 3 whereon the gasket 4 is mounted. It is so constituted that the locking material 6 is rotated as indicated by an outline arrow in a colored background in the selected drawing, so that the periphery rim 2a of the opening portion 2 is sandwiched between the locking material 6 and the lid plate 3 so as for them to be able to be fixed with the gasket 4 being stamped. On the lid plate 3 side surface of the locking material 6, sloped surfaces 6b, 6c are formed at its end portions in the shorter side direction, with a pressing surface 6a at the center side in the shorter side direction being so constituted as to protrude farther from both the ends toward the lid plate 3 side. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
