<P>PROBLEM TO BE SOLVED: To provide a casing structure enabling an operation from opening an upper lid to laying the same under a case body by two easy movement actions. <P>SOLUTION: The casing structure includes; a case body 11 having a guide groove 17; and the upper lid 31 having a spindle part 37 guided by the guide groove 17 and movable from a state of completely covering the case body 11 to a state of being laid on the undersurface 13a. Each spindle part 37 includes a fan-like cross section and includes one side margin 38 in a radial direction located horizontally in a depth direction when the lid completely covers the case body, and the guide groove 17 includes: a fan-like groove part 17a pivotally supporting the spindle part 37 when the lid completely covers the case body; a circular groove part 17b in communication with the fan-like groove part 17a to turn the spindle part 37 to the lid opening angle of 180 degrees; and a horizontal groove part 17c in communication with the circular groove part 17b to guide the upper lid 31 horizontally until the upper lid 31 is laid on the undersurface 13a of the case body 11. <P>COPYRIGHT: (C)2010,JPO&INPIT |
