It is configured to be slidable in the length direction of 11. The joint material
A screw hole (tap hole) 46 is formed at each of two (plural) positions in the length direction of the main runner 11 in each side plate portion of the 45. A bolt 47 is provided through the elongated hole 17 of the main runner 11 from outside, and the bolt 47 is
By being screwed into 46, the joining material 45 is fixed between the ends of the main runner 11.

The operation of the above embodiment will be described below. In order to dispose the ceiling runner 10 below the ceiling structure 1, first, as shown in FIG. 11A, the runner holder 30 is arranged at a predetermined position. That is, the bolt 3 provided with the runner holder 30 is coupled to the insert nut 2 by a screwing operation, thereby disposing the runner holder 30 at a predetermined position. The level adjustment and the direction adjustment of the runner holder 30 are performed based on the screwing amount at that time.

In this state, the main runner 11 is lifted, and the stationary locking portion 33 is fitted into one side of the pair of rectangular holes 15 as shown in FIGS. 4 and 11B. This fitting (lifting) is performed until the upper surface of the upper plate 12 is brought into contact with the lower surface of the side plate portion 32.
Is made to face one end of the locked portion 16 in the length direction of the main runner 11. At this time, the movable locking portion 34 is rotated upward around the horizontal pin 37 by abutting on the upper surface of the upper plate 12.

Next, the locked portion 16 is
Are moved relative to each other, that is, the main runner 11 is moved in the length direction A, and one end of the locked portion 16 is made to protrude into the recessed portion 36 of the stationary locking portion 33, and the slip-off preventing surface 33a is Is pressed against the lower surface at one end to engage the one end. At this time, the movable locking portion 34 is provided on the other side of the rectangular hole 15 formed in the pair.
The movable locking portion 34 is pivoted downward B about the horizontal pin 37 to be fitted into the rectangular hole 15 and the disengagement prevention surface 34 a is pressed against the other end of the locked portion 16. By doing so, the other end side is engaged. The pressing operation by the downward rotation B can be performed by the weight of the movable locking portion 34 or by a forced operation by the operator.

By such a one-touch operation, FIG.
As shown in FIGS. 3 and 11C, the main runner 11 can be disposed below the ceiling structure 1 via a plurality of runner holders 30. At that time, the runner holder 30 is
Prevents the main runner 11 from dropping, and the movable locking portion 34 prevents the main runner 11 from slipping (prevents relative movement in the reverse direction).

Then, by the same operation as described above, the main runners 11 can be linearly added to each other as shown in FIG. 9 and FIG. At this time, the additional joint is provided by inserting a joining material 45 between the ends of the main runner 11, and the elongated hole 17 of the main runner 11 is inserted into the screw hole 46 of the fitted joining material 45. By screwing the bolt 47 passed from the outside to the main runner
The joining material 45 can be fixed between the ends of the main runner 11, so that the ends of the main runner 11 that are linearly connected can be firmly connected.

When the main runner 11 group is linearly spliced and arranged, and the runner holder 30 cannot be used at the end of the main runner 11 group, as shown in FIG. Plate 18 is used. That is, the through hole 18 formed in the short portion of the joint plate 18
The joint plate 18 is fixed to the side structure 6 by screwing the bolt 19 passed through a into the insert nut 2.
Then, the bolt nut 20 is applied from the long hole 18b formed in the long portion to the rectangular hole 15 so that the joint plate is formed.
Fix 18 to the main runner 11. As a result, the end of the main runner 11 group can be supported.

The sub-runner 21 can be provided between the main runners 11 arranged side by side as described above. That is, the locking members 40 are fitted into both ends of the sub-runner 21, respectively, and one of the locking members 40 has the locking portion 40a attached to the end surface 21.
a of the sub-runner 21 in a state protruding from the
By screwing a fastening fixture 43 passed from the outside to the screw hole 41, it is fixed to the sub-runner 21 side at the protruding position, and the other has its locking part 40a retracted with respect to the end face 21a. In this state, the fastening fixture 43 passed through the long hole 27 of the sub-runner 21 from the outside is lightly screwed into the screw hole 41, so that the sub-runner 21 is temporarily fixed to the sub-runner 21 at the projecting position.

In this state, the sub-runner 21 is lifted,
