<p>PROBLEM: Disclosed is a connecting structure that enables a lid body to be connected by the slight rotation thereof in either direction, and that is tolerant of use in many environments including sandy or dusty environments. MEANS FOR SOLVING THE PROBLEM: A connecting structure 1A for connecting a first member 2A and a second member 3A, wherein the first member 2A comprises a connecting upright portion 21 and a plurality of locking flanges 22 provided to extend outwards along the circumferential direction of the outer side surface of the connecting upright portion 21, while the second member 3A comprises a connecting side-wall portion 32 that overlies the connecting upright portion 21 and a plurality of locking projections 33 provided to extend inwards from the inner side surface the connecting side-wall portion 32. The bottom faces of the locking flanges 22 distend downwards in a convex curved shape, and when the second member 3A is overlaid on the first member 2A and rotated, the upper faces of the locking projections 33 are guided with sliding contact along the convex curved bottom faces 23 of the locking flanges 22 and locked at the lowermost position of the convex curved bottom faces 23.</p> |
