Although the latter wiring structure does not have the above-mentioned problems, when passing the wire through the grommet attached to the through hole, it is necessary to pass the long wire through the through hole and grommet from one end. Moreover, there is a problem in that the work of pulling out the wiring from within the wiring pit is extremely troublesome.

In view of this point of view, the present invention is provided along the opening edge of a notch opening that is formed in the lid of a wiring pit and is open on the side thereof, and has an abbreviated cross-sectional shape. The edge frame body having an inward protruding edge at its lower end is fitted with and supports an inner lid body composed of a plurality of divided inner lid members, so that each of the inner lid members can be attached and removed in the vertical direction. At the same time, the inner cover member positioned on the notch opening side is snapped onto the edge frame body, and a through hole is arbitrarily opened 1' in the center of the partition edge between the adjacent inner cover members to form a wiring bit. The inner wiring is pulled out to the outside, and the inner cover member is removed as appropriate, the wiring inside the wiring pit is inserted into the edge frame from the side, and the wiring is inserted into the arbitrarily opened through hole. The present invention provides a wire passage structure for a wiring pit cover body that can solve the above-mentioned problems by sequentially snapping inner cover members to an edge frame body to close a notch opening.
