PROBLEM TO BE SOLVED: To automate both of opening action and closing action of a lid element. SOLUTION: The lid element opening/closing mechanism comprises a closing lock releasing mechanism portion 21 capable of releasing a magnetically attraction state between both by making a partner side closing lock magnet 14 react to separate from a lid side closing lock magnet 11 at a closing position; a closing action mechanism portion 31 capable of moving a lid element 5 from an opening position to the closing position against its weight, while using magnetic repulsion between both by making a partner side closing action magnet 16 move close to a lid side closing action magnet 13 at the opening position; and a returning mechanism 41 returning the closing lock releasing mechanism portion 21 to the closing position of the lid element 5 by movement from the opening position to the closing position of the lid element 5 due to the closing action mechanism portion 31.
