On its inner peripheral surface, a first protrusion 7 that can be engaged with the valley portion 2 of the compound tube 3 (specifically, the valley portion 2 of each of the electric wire protection tubes 3 1 and 3 2 forming the compound tube 3) is almost entirely formed. It is a projecting piece all around the lap. It goes without saying that the insertion hole 6 is of a size capable of inserting the compound pipe 3 in the state where the first protrusion 7 is provided. However, in order to make it easy to insert the multiplex tube 3 into the insertion hole 6, when the multiplex tube 3 is inserted into the insertion hole 6, between the two electric wire protection tubes 3 1 and 3 2 forming the multiplex tube 3 The bottom plate 15 of the mountain portion 20 that enters

A semicircular arc-shaped second projecting member 8 that is engaged with another trough portion 2 different from the trough portion 2 with which 7 is engaged is provided. Specifically, as shown in FIG.
The bottom plate 15 of the box body 4 is provided with a rib 24 having two semi-circular cutouts having the same radius as the radius of the insertion hole 6, and the second projection 8 is projected at the edge of the cutout. It is set up. However, in this case as well, in order to make it easier to insert the multiple pipe 3 into the insertion hole 6, the mountain-shaped portion 2 of the rib 24 that is inserted between the two electric wire protection pipes 3 1 and 3 2 that form the multiple pipe 3.
The second protrusion 8 is not provided on the top portion (flat portion 28) of 6 (FIG. 3).

As shown in (b) of the same figure, the second protrusion 8 is provided in an arbitrary valley portion 2 (the valley portion 2 1 closest to the tip in FIG. 5b) of the compound tube 3 (FIG. 5b).
And the mountain portion 1 (1 1 ) adjacent to the valley portion 2 2 which is located in front of the valley portion 2 1 by a predetermined pitch in the inserting direction of the double pipe 3.
Then, the first protrusion 7 is locked on the double tube 3, and then the compound tube 3 is rotated in the direction of the arrow in FIG. Rotates the double tube 3 in the same direction, as shown in FIG. 5 (c), the ridges 1 1

Therefore, even if a bending force is applied to the compound pipe 3, it is difficult to unintentionally release the fixation of the compound pipe 3 and the box body 4, and especially when a bending force is applied upward (toward the opening), The tube 3 and the box body 4 are almost never unlocked. When removing the compound tube 3 from the box body 4, the compound tube 3 is rotated in the opposite direction (the direction opposite to the arrow in FIG. 5b) to move the first and second protrusions 7, 8 and the valleys 2 2 and 2 1 are disengaged. Also in this case, FIG.
Unless a bending force of a predetermined value or more is applied in the direction opposite to the arrow of (b), the engagement between the first and second protrusions 7 and 8 and the valleys 2 2 and 2 1 will not be released. Absent.

楕円形とすることもできる。As shown in FIG. 6A, in the first protrusion 7 shown in FIG. 3, the substantially lower half of the insertion hole 6 (approximately half of the bottom plate side) can be omitted. However, from the viewpoint of firmly fixing the compound pipe 3, both ends 7a of the first projecting member 7 are arranged at the radial center of the insertion hole 6 (at the position indicated by the alternate long and short dash line in FIG. 6a).
It is desirable that the bottom plate 15 be slightly projected to the side.
In this case, it is desirable to chamfer the end portion 7a of the first protrusion 7 in order to easily insert the multiple tube 3 into the insertion hole 6. In addition, as shown in FIG.
Of the two mountain-shaped portions 20 in the insertion hole 6 shown in (a), the mountain-shaped portion 20 on the bottom plate 15 side can be omitted. Also in this case, it is desirable to project both ends 7a of the first protrusion 7 to the bottom plate 15 side from the radial center of the insertion hole 6 (the position indicated by the dashed line in FIG. 6b). It is desirable to chamfer the end 7a.
6 (a) and 6 (b), the rib 24 and the second protrusion 8 provided therein are not shown. Further, the shape of the insertion hole 6 is not limited to the one shown in the figure, and the shape can be appropriately changed to facilitate insertion of the multiple pipe. For example, it may be an elliptical shape that is elongated in the height direction of the side wall (vertical direction in FIGS. 6A and 6B).

内に挿通されている電線が傷付く虞がない。The indoor wiring box of the present invention has the following effects. (1) The electric wire protection tube can be attached to the box body without using a member such as the connector M shown in FIG. 10 which is separate from the box body and the double tube. (2) The first protrusion is engaged with the valley portion from one side in the radial direction, and the second protrusion is engaged with the other valley portion from the other side in the radial direction. That is, since the wire protection tube is fixed from both sides in the radial direction facing each other, it is difficult for the protection tube to come off from the box body regardless of the radial direction of the protection tube. (3) Since screws and pins are not used to fix the electric wire protection tube to the box body, there is no fear that the electric wire inserted into the electric wire protection tube will be damaged by them.
