  The support fitting of Patent Document 1 has a configuration in which an elastic clamping plate is brought into contact with the outside of the opening of the channel material, and a cover, a lighting fixture, or the like is connected to a component fixing screw that protrudes from the inside of the channel material to the outside of the opening. ing. In this configuration, a suspension bolt or the like cannot be connected to the sandwiching element temporarily fixed to the inside of the lip portion, and there is a disadvantage that the application is limited.

  If the nut metal fitting of patent document 2 was devised, it would be possible to connect a suspension bolt, and it could be used in many applications as a construction material, a wiring duct, or a metal fitting for metal wire. However, the spring material mounted inside the channel material is not stable, and there is a possibility that the nut fitting may move during the operation of connecting the suspension bolt.

  With the support fitting of Patent Document 3, the nut fitting attached to the inside of the channel material can be maintained in a stable state. However, since a belt-like elastic material bent into a substantially Z-shaped side surface is used, it takes time and labor to attach the elastic material to the channel material. That is, the elastic material of Patent Document 3 needs to be combined with a nut fitting and an elastic material for each construction. Further, when adjusting the mounting position after mounting the nut fitting inside the channel member, it is necessary to move the elastic member and nut fitting attached inside the lip portion at the same time. As described above, the support metal fitting of Patent Document 3 has a problem in workability at the time of mounting and position adjustment.

  On the other hand, the fixing bracket shown in FIG. 9 can solve the problems in versatility and workability as in Patent Documents 1 to 3. However, once the fixing bracket is locked to the lip portion P1 of the channel material P, there is a problem that it cannot be removed from the opening again. In other words, the fixing bracket is inserted into the opening of the channel material P by swinging the locking portion 100 connected to the fixing portion 200 via the elastic connecting body 300 (see FIG. 9A). It can be locked to the lip portion P1. However, after the locking portion 100 is locked to the lip portion P1, the fixing portion 200 that is in contact with the opening prevents the locking portion 100 from swinging, and thus the locking portion 100 cannot be removed from the opening. It is configured. Therefore, in order to remove the fixing bracket once mounted, it is necessary to move the fixing bracket to the longitudinal end portion of the channel material P (see FIG. 9B). However, in a state where other members are attached to the opening of the channel material P, such movement becomes difficult, and the fixing fitting attached to the opening is often left as it is.
