To provide a lid body locking structure capable of extremely easily performing opening/closing operation, and having no possibility of breaking unexpectedly.
In the lid body locking structure, when a lid body 12 pivoted on a main body part 14 is rotated in the closing direction, a locking member 31 is displaced in the anti-lid body side against an energizing force, and the lid body 12 is held under a closed condition. In this lid body locking structure 21, a sliding locking member 41 sliding along the locking member 31 is provided, and an operating part 42 positioning on the outside of the locking member 31 is formed on the sliding locking member 41. A pressing part 44 for pressing a part to be pressed of the locking member, and a rotation regulating part 45 for preventing a locking nail 32 of the locking member 31 from rotating to the anti-lid body side, are formed. On the locking member 31 or in the vicinity thereof, when the rotation regulating part 45 is at a position for preventing the locking member from rotating, and the lid body 12 rotates in the closing direction to interfere to the locking member 31, a locking allowing structure for rotating and/or deforming the locking nail 32 to the anti-lid body side is formed.
