To provide a hidden door lock that also has a safety function to prevent improper unlocking.SOLUTION: Included are: a lock rod horizontally retractable from a lock rod hole formed on the door tip side end face of a lock member; and a push member which is attached to the inside of a door frame and has a plate-like extension part which is released in a shortened state when a door plate in a closed state is pushed in and extends a fixed length in the door opening direction. In addition, included is: a receiving hole formed at a face on the side of the door plate of the extension part and constitutes a locked state when the lock rod is inserted under a door closed state. The extension part is formed in a lock rod protection part covering the lock rod hole, and the outside surface of the door plate in the closed state is formed on substantially the same surface as the outside surface of the door frame. Provided are a highly safe hidden door lock and a hidden door, in which the door plate is pushed out in the outdoor direction together with the lock rod in the locked state by the extension operation of the extrusion member to be in a half-opened state, but contact with the lock rod from the outside becomes difficult through a gap between the door frame and the door plate in the half-opened state by a lock rod protection part, and the door is prevented from moving in the pushing direction even when the lock rod is directly pushed by an auxiliary rod.SELECTED DRAWING: Figure 4
