As shown in FIG. 10, the bottom wall 33 of the rectangular cylinder 31 is disposed at a position shifted upward from the lower end of the inner side wall 24, and has a so-called raised bottom structure. A flexible piece 40 is formed on the bottom wall 33 as shown in FIG. The flexible piece 40 cuts a part of the bottom wall 33 into a cantilever shape by forming a slit 42 from the center of the bottom wall 33 to the inner side wall 24 side having the tag rear end locking hook 25. It becomes. Further, the flexible piece 40 extends in a direction orthogonal to the inner side wall 24 having the tag rear end locking hook 25, and its tip is abutted toward the inner side wall 24. Further, a pair of reinforcing ribs 41 and 41 are formed on the bottom surface of the bottom wall 33 so as to protrude. As shown in FIG. 10, the reinforcing ribs 41, 41 extend along both side edges of the flexible piece 40 and extend to the inner side wall 24 opposite to the inner side wall 24 having the tag rear end locking hook 25. And connected to the inner side wall 24. It should be noted that the protruding amount of the reinforcing rib 41 from the bottom wall 33 is larger at the portion removed from the flexible piece 40 than at the portion positioned below the flexible piece 40.

  As shown in FIG. 13A, an engaging recess 45 is formed at the distal end of the flexible piece 40 by cutting away the center in the width direction. The engaging recess 45 has a quadrangular planar shape, and the engaging recess 45 and the tag rear end locking hook 25 overlap each other in the vertical direction. And the part which shape | molds the lower surface of the tag rear end latching hook 25 among the resin molds for shape | molding the pallet 10 passes the engagement recessed part 45. As shown in FIG.

  The tag front end positioning portion 35 </ b> V of the present embodiment is disposed at the distal end portion of the flexible piece 40.

  This completes the description of the configuration of the pallet of this embodiment. Next, the effect of the pallet of this embodiment is demonstrated. In order to attach the IC tag 90V to the pallet, the IC tag 90V is inserted into the tag receiving opening 30 from the tag protruding piece 95 side, and the tag protruding piece 95 is inserted into the engaging recess 45 as shown in FIG. In addition, both side portions of the tag protruding piece 95 of the IC tag 90V are inserted into the receiving groove 44 between the first and second back side upstanding walls 46 and 47.

  Then, the IC tag 90V is elastically deformed in a curved state in the vertical direction, and the rear end portion of the IC tag 90V is submerged below the tag rear end locking hook 25, and then elastically restored, so that FIG. As shown in FIG. 12B, the rear end portion of the IC tag 90 </ b> V is sandwiched between the tag rear end locking hook 25 and the inner side wall 24. At this time, the flexible piece 40 is bent downward by the elastic force of the IC tag 90V, and the interval between the tag front end positioning portion 35V and the tag rear end locking hook 25 is widened. Thereby, even if it is IC tag 90V which is hard to elastically deform, it can be easily attached between the tag rear end latching hook 25 and the tag front end positioning part 35V.

  When the attachment of the IC tag 90V is completed, the tag rear end locking hook 25 holds the rear end portion of the IC tag 90V between the inner side wall 24, while the tag front end positioning portion 35V holds the front end portion of the IC tag 90V inside. Since the IC tag 90V is held obliquely with respect to the inner side wall 24 because it is held at a position away from the side wall 24, the whole except for the rear end of the IC tag 90V is lifted from the inner side wall 24. . Thereby, transmission of vibration to the IC tag 90V can be suppressed. In addition, the tag rear end locking hook 25 engages with the recess formed in the rear end of the IC tag 90V, and the tag protrusion on the front end of the IC tag 90V projects into the engagement recess of the tag front end positioning portion 35V. Since they are engaged, the lateral displacement of the IC tag 90V is prevented.

  Thus, also by the structure of this embodiment, IC tag 90V can be attached to the inside of a pallet without using a holder similarly to 1st Embodiment. Further, an engaging recess 45 is formed in a portion overlapping the tag rear end locking hook 25 in the vertical direction, and the tag rear end locking hook 25 and the tag front end positioning portion 35V are formed in the width direction of the inner side wall 24 and the width thereof. Since the arrangement is shifted in a direction orthogonal to the direction, the mounting portion of the IC tag 90 on the pallet 10 can be molded only by a molding die that is opened in the vertical direction of the pallet 10. By these, the manufacturing cost of a pallet can be held down.
