3. By extending the left side wall 14 and the right side wall 15 to the front side F, it is formed in a bottomed rectangular tube shape having an opening 10 on the front surface. Each of the rear side wall 11, the upper side wall 12, the lower side wall 13, the left side wall 14, and the right side wall 15 has a closing plate 1 which can be separated by applying a pressing force.
6 are provided with connection ports 17 for a plurality of conduit tube connectors.

A first groove 1 having an arc-shaped cross section and extending in the left-right direction is formed on the outer surface of the upper side wall 12 above the extension of the rear side wall 11.
8 is formed upward, and a second groove 19 having a circular arc-shaped cross section is formed downward on the outer surface of the lower side wall 13 on a lower extension line of the rear side wall 11.

An elastically deformable upper arm piece 20 is connected to a central portion of the upper side wall 12 in the horizontal direction near the first groove 18, and a central portion of the lower side wall 13 in the horizontal direction near the second groove 19. One lower arm piece 21 that can be elastically deformed is continuously provided. The upper arm piece 20 is attached to the upper side wall 1.
2. An L-shaped section having a base portion 20A rising in a direction away from the outer surface of the base member 2 and a pressing portion 20B extending from the upper end of the base portion 20A toward the rear side to a position facing the first groove 18. A guide surface 22 formed by a downward inclined surface that extends obliquely toward the distal end is formed on the distal end side of 20B, and the engaging groove 24 opens downward at a position facing the first groove 18 in the pressing portion 20B. It is formed in the left-right direction. Further, the lower arm piece 21 includes a base 21A that is lowered in a direction away from the outer surface of the lower side wall 13 and
A L-shaped section having a pressing portion 21B extending from the lower end of A to a position facing the second groove 19 facing downward from the lower end, and extends obliquely toward the distal end of the pressing portion 21B. A guide surface 23 formed by an upwardly inclined surface is formed, and an engagement groove 24 is formed at a position facing the second groove 19 in the pressing portion 21B so as to open upward and in the left-right direction.

Next, the wiring box main body 1 having the above-described configuration.
The procedure for attaching the upper side to the upper horizontal fixing bar 2A and the lower horizontal fixing bar 2B will be described. Upper horizontal fixing bar 2
A and the lower horizontal fixing bar 2B are connected to the wiring box body 1.
3 can be elastically deformed and deformed when pushed from the front side, and as shown in FIG. The distance H is determined by the first groove 18 in the wiring box body 1.
And the second groove 19 are set to a value substantially equal to the vertical interval H1. First, as shown in FIG. 4, the wiring box main body 1 is positioned close to the front sides of the upper horizontal fixing rod 2A and the lower horizontal fixing rod 2B, and the upper horizontal fixing rod 2
A, the first groove 18 and the upper arm piece 20 face each other in the front-rear direction, and the second groove 19
And the lower arm piece 21 are opposed to each other in the front-rear direction.

In this state, for example, the upper side of the wiring box body 1 is pushed backward (in the direction of arrow R). Thereby, as shown in FIG. 5, the upper horizontal fixing bar 2 </ b> A comes into contact with the guide surface 22 of the upper arm piece 20. By pushing the wiring box body 1 further rearward from this state, the upper horizontal fixing bar 2A is guided by the guide surface 22 and the upper arm piece 20
6A and 7B are elastically deformed upward.
As shown in FIG. 7, the upper horizontal fixing bar 2A is received in the first groove 18 and the engaging groove 24 of the upper arm piece 20, and the upper horizontal fixing rod 2A is pressed by the upper arm piece 20 from above. And lock. Then, the lower side of the wiring box main body 1 is pushed backward (in the direction of arrow R). As a result, as shown in FIG.
Abuts on the guide surface 23 of the lower arm piece 21. By further pushing the wiring box body 1 backward from this state, the lower horizontal fixing bar 2B is guided by the guide surface 23 to elastically deform the pressing portion 21B of the lower arm piece 21 downward,
