An elevator car ceiling apparatus comprising: an external ceiling plate in which a rescue hatchway is disposed; an internal ceiling plate in which an inspection hatchway that faces said rescue hatchway is disposed, and that is disposed further inside a car than said external ceiling plate; a rescue hatchway opening and closing cover that is displaceable between a rescue hatchway closing position that closes said rescue hatchway, and a rescue hatchway opening position that is positioned further outside said car than said rescue hatchway closing position and that opens said rescue hatchway; and an inspection hatchway opening and closing cover that is held by said internal ceiling plate when in an inspection hatchway closing position that closes said inspection hatchway, and that is removed from said internal ceiling plate by being displaced from said inspection hatchway closing position to a holding release position that is offset horizontally to disengage holding by said internal ceiling plate by lowering the inspection hatchway opening and closing cover into the car, and characterized by further comprising: an inspection hatchway locking apparatus which comprises: an inspection hatchway external operating portion that can be operated manually from outside said car; an inspection hatchway internal operating portion that can be operated from inside said car only using a special purpose key; and an inspection hatchway lock portion that can be displaced between a locked position that stops displacement of said inspection hatchway opening and closing cover from said inspection hatchway closing position to said holding release position and an unlocked position that releases stopping of said displacement of said inspection hatchway opening and closing cover by operating either said inspection hatchway external operating portion or said inspection hatchway internal operating portion. an external ceiling plate in which a rescue hatchway is disposed;
