LID BODY

To provide a lid body capable of easily forming an opening.SOLUTION: A lid body 100 is provided with: a lid base part 10 in a generally flat plate shape having an opening part 11 passing in a plate thickness direction V; and an open/close part 40 in a generally flat plate shape connected with a peripheral edge 11a of the opening 11 of the lid base part 10 through a first uncut remained part 20 and a second uncut remained part 30 and capable of rotating relating to the lid base part 10 around a rotational shaft passing through the first uncut remained part 20 and the second uncut remained part 30 as a center, wherein the open/close part 40 rotationally moves from a first position positioned on a generally identical plane of the lid base part 10 and the open/close part 40 to a second position on which one surface of the lid base part 10 in a vertical direction V and one surface of the open/close part 40 abut to each other, and the open/close part 40 covers the opening 11 when it is at the first position, and when a pressed-in part 41 arranged on one side across the rotation shaft is opened to the other side in the vertical direction V, a lid part 42 arranged on the other side across the rotation shaft is opened to one side and at least one part of the opening 11 is exposed.SELECTED DRAWING: Figure 2 【課題】容易に開口を形成できる蓋体を提供する。【解決手段】蓋体１００は、略平板状で、板厚方向Ｖに貫通する開口部１１を有する蓋基部１０と、第一切り残し部２０と第二切り残し部３０とを介して蓋基部１０の開口部１１の周縁１１ａと接続され、第一切り残し部２０と第二切り残し部３０とを通る回転軸を中心として蓋基部１０に対して回動可能な略平板状の開閉部４０と、を備え、開閉部４０は、蓋基部１０と開閉部４０とが略同一平面上に位置する第一位置から、蓋基部１０の上下方向Ｖにおける一方側の面と開閉部４０の一方側の面とが当接する第二位置まで回転移動し、開閉部４０は、第一位置にあるとき、開口部１１を覆い、回転軸を挟んで一方に設けられた押込み部４１が上下方向Ｖにおける他方側へ開いたとき、回転軸を挟んで他方に設けられた蓋部４２が一方側に開いて開口部１１の少なくとも一部が露出する。【選択図】図２
