OPENING/CLOSING MECHANISM AND UNDERFLOOR INSPECTION DOOR
To improve safety without opening a lid when a downward load is applied in a first state where the lid covers a recess.SOLUTION: An opening/closing mechanism 60 includes a body base 10 having a first recess and a second recess 21, and a lid 40. A support mechanism for movably supporting the lid 40 with respect to the body base 10 is provided on a side surface defining the second recess 21 and a side surface of the lid. The side surface defining the second recess 21 is formed with a support portion 30 that contacts a lower portion of the lid 40 in a first state where the lid 40 covers the second recess 21. The support mechanism is configured such that the lid 40 can take the first state, a second state where the lid 40 is moved in a first direction from the first state, and a third state where the lid 40 is moved below the second recess 21 to open the second recess 21 in an upright state in which the lid 40 is rotated about a rotation axis G from the second state, with respect to the body base 10.SELECTED DRAWING: Figure 7
【課題】蓋が凹部を覆う第１状態において下方への荷重がかかっているときには開かず安全性を向上させる。【解決手段】開閉機構６０は、第１凹部と第２凹部２１とを有する本体ベース１０と、蓋４０とを含む。第２凹部２１を画定する側面及び蓋の側面には、蓋４０が本体ベース１０に対して移動可能に支持する支持機構が設けられている。第２凹部２１を画定する側面には、蓋４０が第２凹部２１を覆う第１状態において、蓋４０の下部と当接する支持部３０が形成されている。支持機構は、第１状態と、蓋４０を第１状態から第１方向に移動させた第２状態と、蓋４０を第２状態から回転軸Ｇを中心に回動させた起立状態で第２凹部２１の下方に移動させ第２凹部２１を開放する第３状態とを、蓋４０が本体ベース１０に対して取ることが可能に構成されている。【選択図】図７
