  Alternatively, it is desirable that the above-described protrusion 30 is disposed on the edge of the base portion 20 in one of the above-described regions. When the protrusion 30 is disposed at the edge of the base portion 20, it is easier to push up the protrusion 30 than when the protrusion 30 is disposed near the insertion shaft portion 24. As a result, the hooking portion 26 can be easily directed in a direction that can be hooked on the plate-like portion 220.

Further, it is desirable that the above-described retaining pulling portion 28 has the curved surface portion 70 . Songs surface portion 70 faces the hook portion 26. When the retaining stop portion 28 has the curved surface portion 70, it is possible to reduce the resistance to ride on the retaining stop portion 28 as compared to the case where the curved surface portion 70 is not provided.

  Further, it is desirable that the protrusion 30 described above has an upright surface 80. The upright surface 80 stands upright from the back surface 92 of the base portion 20. When the upright surface 80 stands upright from the back surface 92 of the base portion 20, the upright surface 80 hits the plate-like portion 220, so that the possibility that the direction of the hooking portion 26 changes naturally can be reduced. When the possibility becomes low, it is possible to reduce the possibility that the clamp tool 10 is naturally detached from the groove 210.

  Moreover, it is desirable that the above-described binding material mounting portion 22 includes a plurality of support columns 50, a roof portion 52, and a lever portion 54. The plurality of support columns 50 face each other. The roof part 52 straddles the tip of the column 50. The lever portion 54 protrudes from at least one of the support column 50 and the roof portion 52 in a direction different from the protruding direction of the support column 50. Thereby, when a force is applied to the lever portion 54, the hook portion 26 can be easily directed in a direction in which the hook portion 26 can be hooked on the plate-like portion 220.
