  Further, since the fixture 30 has the second movement restricting portion 52, the bottom plate 22A of the gantry portion 22, the first fixing portion 34, and the lower side portion 36B are maintained in parallel when assembled to the flange portion 92. The Therefore, it is possible to avoid the lower part 36 </ b> B from interfering with the flange part 92, and the header holder 20 and the fixing tool 30 can be smoothly arranged at predetermined positions of the flange part 92.

  Further, according to the fixture 30 of the present embodiment, both the gantry 22 and the flange 92 are provided between the distal end surface 35S of the movement restricting portion 35 and the distal end surface 38S of the bolt 38 formed in the first fixed portion 34. Since the header holder 20 can be fixed to the flange portion 92 in one stage of operation.

  Further, since the header holder 20 is arranged on the one surface 92A side of the flange portion 92, the header holder 20 can be arranged in a space-saving manner using the dead space of the H steel 90.

  Moreover, since the header holding part 28 is arrange | positioned above the position which clamps the mount part 22 and the flange part 92 with the fixing tool 30, a moment does not act on a clamping part, and it can fix stably.

  Further, since the movement restricting portion 35 formed on the first fixed portion 34 abuts against the inner surface of the facing portion 26 of the gantry 22 and the movement of the gantry 22 in the plate width direction Y is restricted, The backlash is suppressed and can be stably fixed.

  Further, since the convex portion 26A of the gantry 22 is engaged with the concave portion 35A of the fixture 30, and the movement of the gantry 22 in the direction perpendicular to the plate width direction Y is also restricted, rattling of the gantry 22 is suppressed. Can be fixed more stably.

  Further, since the pressing portion 33A is in contact with the one surface 92A of the flange portion 92, the gantry portion 22 can be fixed more stably. In addition, since the pressing portion 33A has a corrugated portion that contacts the one surface 92A, it works so that the convex portion bites into the attached member when fixed, and stably fixes the fixture to the attached member. be able to.

  Further, since the escape portion 33B is formed in the bent portion between the pressing portion 33A and the intermediate portion 36A, the tip end surface 92S of the flange portion 92 can be brought into contact with the intermediate bent portion 33M, and the frame The part 22 can be fixed stably.
