description To provide a lock mechanism capable of surely preventing careless rotation of an operation shaft and being easily mounted on an inner frame, and a building inspection hole provided with such a lock mechanism.SOLUTION: A lock mechanism 1 includes: an operation shaft 8 provided at a position opposed to an inner surface of an outer frame in an inner frame; a bearing 9 for rotatably mounting the operation shaft 8 to the inner frame; an operation receiving part 8E provided on the operation shaft 8 and receiving the rotating operation to the operation shaft 8; a locking part 10 provided on the operation shaft 8 and detachably locked to the outer frame by the rotation of the operation shaft 8; and a spring member 11 inserted between the bearing 9 and the operation shaft 8 and having a sandwiching part 11C sandwiching the operation shaft 8 therebetween.SELECTED DRAWING: Figure 7 【課題】操作軸の不用意な回転を確実に防止でき、且つ内枠への取付けが容易なロック機構と、このようなロック機構を備えた建物点検口と、を得る。【解決手段】ロック機構１は、内枠における外枠の内面に対向する位置に設けられる操作軸８と、内枠に操作軸８を回転可能に取り付ける軸受９と、操作軸８に設けられ、操作軸８への回転操作を受ける操作受部８Ｅと、操作軸８に設けられ、操作軸８の回転により外枠に係脱可能に係止する係止部１０と、軸受９と操作軸８との間に差入れられ、操作軸８を間に挟み込む挟み部１１Ｃを有するバネ部材１１と、を備える。【選択図】図７
