It is known that a wiring duct is formed by externally fitting an outer channel, which is substantially U-shaped in side view, to the inner channel of the above, to form a wiring duct.

In the wiring protection cover, the bottom plate of the inner channel is fixed to the wall surface or the floor surface with nails, and power lines, communication lines, etc. (hereinafter referred to as storage wiring) are housed in the inner channel, and The outer channel is fitted over the inner channel to conceal the inner channel and the storage wiring, and the inner channel and the outer channel are fitted to each other so that the left and right outer plates of the outer channel and the left and right inner plates of the inner channel are In this structure, the engaging elements that are overlapped with each other and project from the left and right outer side plates are engaged with the engagement receiving portions provided on the left and right inner side plates of the inner channel to hold the outer channel in the inner channel.

[0004]

However, in particular,
When the wiring protection cover is installed on the floor, the wiring protection cover is often stepped on, and as a result, the left and right side surfaces of the inner channel are distorted and the outer channel often comes off the inner channel. If the outer channel is left unattached in addition to being damaged, it may cause a fall during walking, which is dangerous.

As a structure having such a problem solved, for example, as shown in FIG. 7, the structure of the wiring protection cover disclosed as an example in Design Registration No. 1099434, that is, a schematic side view A wiring protection cover in which a lid member having engaging edges is externally fitted to left and right engaging ends that are free ends in a channel of the shape of the symbol (hereinafter referred to as prior design 1
Say. ) Is known.

According to this structure, although the channel has sufficient strength for engagement with the lid member, once the wiring is housed, the left and right engaging ends of the channel are sandwiched by the housed wiring and the lid member. Even if the left and right side walls are pinched with fingers and pushed inward, the stored wiring interferes with the removal of the lid member from the channel, making it extremely difficult to remove the lid member. is there.

Further, as a structure different from the prior art 1 and the prior design 1, the structure of the wiring protection cover disclosed in Design Registration No. 1085431, that is, the left and right engaging edges of a substantially U shape in side view is provided.

Compared with, the detachment of the channel and the lid member is somewhat unlikely to occur, but the strength of the left and right walls is
It is remarkably inferior to the prior art 1, there is a problem in that the left and right side surfaces of the channel of the prior design are bent from the root and unusable, or the lid member falls into the channel and comes off.

Further, when the storage wiring is accommodated in the wiring protection cover according to the preceding design, the storage wiring often rises in a wavy manner. In such a case, the lid member is extremely attached. It will be difficult.

Further, in recent years, the storage wiring is often changed from the conventional one having two cores to the one having three cores. In this case, the outer diameter dimension of the storage wiring is for wiring protection. It is oversized, and it is difficult to store the stored wiring in order to continue to use the conventional wiring protection cover, and there is a problem that a part of the stored wiring that is difficult to store rises like a wave. Become.

Further, in order to prevent the problem from occurring, it is necessary to newly increase the size. However, the larger the size, the more bulky it is at the time of installation, and the aesthetic appearance is impaired. . Under these circumstances, there is a strong demand in the market for a wiring protection cover that does not cause such a situation.

The present invention has been made in view of the above circumstances, and it is possible to prevent detachment of the channel and the lid member, have sufficient strength on the left and right side walls, and accommodate the 3-core or 2-core storage wiring. It is very easy to do, there is no problem that a part of the storage wiring rises like a wave, the lid member can be easily attached to and detached from the channel, the bulkiness at the time of installation is suppressed as much as possible, and the current aesthetic appearance is maintained. It is a problem to be solved to provide an excellent wiring protection cover that can be maintained.

When the storage wiring has an inverted T shape in a side view, when the storage wiring is oversized, the engagement wall acts so as to push the storage wiring, and it is possible to prevent the storage wiring from being bumped up. .

In addition, when the lower sloping surface is formed on the ridge of the channel and the sloping surface on the same extension surface as the lower sloping surface is formed on the engaging wall of the lid member, the storage wiring is oversized. Even if it is, while preventing the storage wiring from interfering with the engagement wall as much as possible,
Even when the interference occurs, it is possible to prevent the engagement wall from biting into the storage wiring or the frictional resistance, and to easily engage and disengage the lid member by the resin elasticity of the engagement wall and the engagement edge portion. You can
