<P>PROBLEM TO BE SOLVED: To provide a case body, and to enable a cover to smoothly open and close without restricting the design of its cover which covers the aperture in an openable and closable way. <P>SOLUTION: The aperture 2c is formed in the case body consisting of a base 1 and an upper cover 2, in such a way that the aperture 2c may be openable and closable by using an access cover 3. In the access cover 3, an arm 31 is formed wherein two or more projections 33 are formed along an arcuate line. The projections 33 are engaged with the upper cover 2 so that a guide 21 may be formed, wherein a slidable arcuate groove 23 is formed. By making the projections 33 slide along the groove 23, the access cover 3 carries out the rotating operation so that it can be opened and closed, while a rotation-center-axis line A of this rotating operation is set on the outside of the case. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
