きる。Next, the step of connecting the narrow channel member 12 to the hanging bolts 4 will be described with reference to FIGS. 3 and 4. First, the connecting metal fittings 10 are received in the form of receiving the hanging bolts 4 in the receiving grooves 30, 30. Is inserted into the suspension bolt 4, and then the narrow channel member 12 is sandwiched between the pair of holding portions 28, with the bottom thereof facing the suspension bolt 4. Further, each bent piece 32 is moved toward the respective opposing portion side, in other words, the rising portions 12a, 12
Ru bent with a finger toward the inside of a. Each bent piece deformed
32 is the end portions 12b, 12b of the rising portions 12a, 12a.
The hanging and the connection of the narrow channel member 12 to the suspension bolt 4 are basically completed. In this state, the pair of upper and lower locking portions 34, 34 are drawn in the vertical direction X perpendicular to the longitudinal direction of the narrow channel member 12 and bite into the screw groove 4 a, thereby connecting the connecting fitting 10 itself to the longitudinal direction of the suspension bolt 4. It locks in the direction Y, and at the same time, prevents the narrow channel member 12 from moving in the longitudinal direction X and the longitudinal direction Y of the suspension bolt. As a result, the narrow channel member 12
However, it is also possible to prevent rotation in the direction Z around the axis along the longitudinal direction, and the connection between the suspension bolt 4 and the narrow channel member 12 becomes very strong. The narrow channel member 12 can be temporarily fixed to the suspension bolt 4 if the bent piece is not completely bent but is slightly bent.

In this case, as shown in FIG. 5B, by slightly shortening the bent piece 32, the bent piece 3
2 can be prevented from lowering the pressure contact efficiency due to the tip of the second contacting the bottom of the narrow channel member 12.

However, when the channel member 12 is narrow, it is necessary to prevent the bent pieces 32 from interfering with each other. Since the bent pieces cannot be formed too long, the bent pieces are relatively difficult to bend. Therefore, in the sixth connection fitting 60 shown in FIGS. 13 to 15, the rising portion 1 of the channel member 12 is attached to one of the holding portions 28, 28.
A hook portion 35 for hooking the end portion 12b of 2a is provided, and a relatively long bent piece 32 is provided on the other of the holding portions 28,28. By increasing the length of the bent piece, labor saving at the time of bending is achieved.
