(2) Conventional Technology Conventionally, as this type of device, for example, a device in which a plug socket is provided on a lid plate of a wiring storage duct is known, and this is an exposed type in which the plug socket is always exposed on the lid plate upper surface. There is a tilt type that raises the plug socket to the top surface of the cover plate only when it is used.However, if the plug socket is made to protrude above the cover plate, the plug socket is relatively large, which may be an obstacle or damage the appearance. In addition, there is a problem that the plug may be inadvertently removed.

Therefore, in order to solve such a problem, for example, Japanese Patent Laid-Open No. 1-
As disclosed in Japanese Patent No. 138916, a duct with a built-in outlet, in which a plug socket is always fixedly housed in a duct body so that a plug of an electric device can be connected to the plug socket in the duct body, is placed at a proper place on the floor. It has already been proposed to arrange an electric wire connected to the plug into a room through a passage opening provided in an upper lid of the duct with a built-in outlet.

(3) Problems to be Solved by the Invention In the above-mentioned proposal, however, the plug socket is immovably mounted in the duct body of the above-described outlet built-in duct. In order to deal with this, a large number of ducts with built-in outlets must be distributed and arranged on the floor in advance, and it is expensive and the floor construction work is troublesome. It could be performed only at the position where the duct with a built-in outlet was installed, and it was extremely limited. Furthermore, even if the lid of the outlet built-in duct is opened and various operations such as inspection and maintenance are performed inside the duct body, there is a problem that the plug socket fixed to the duct body interferes with the work.

An object of the present invention is to provide a floor wiring device that can solve the above problems.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above object, according to a first feature of the invention, a wiring accommodating duct arranged in a floor and an inside of the wiring accommodating duct are provided. A flexible electric wire to be housed in the electric wire and a plug socket connected to a free end of the electric wire and receiving a plug connected to an indoor electric device via a connecting wire in the duct. , A channel-shaped duct main body that extends linearly along the floor surface, and a lid plate that covers the upper opening of the duct main body so as to be openable and closable to form a part of the floor surface. It is supported on the inner wall surface of the duct body so that it can move freely in the duct longitudinal direction in the wiring accommodating duct along with the free end of the electric wire, and the connecting wire is provided on the lid plate. From inside the wiring storage duct through the passage opening It is designed to be pulled out indoors.
