PROBLEM TO BE SOLVED: To provide a lid opening/closing mechanism having an urging means 4 for always urging a lid body 3 to be openable/closable and lockable to an upper surface of a body 2 in a closed condition, capable of urging the lid body in the opening direction with a very simple structure unnecessarily sorting without using any metal, capable of easily assembling, and capable of sufficiently demonstrating the urging force in the opening direction. SOLUTION: The lid opening/closing mechanism comprises the urging means 4 for always urging the lid body 3 in the opening direction by stretching an elastic annular body 7 in an extended condition over a first locking part 5 of a rear of the lid body and a second locking part 6 of an upper part of the body forward thereof. |
