PROBLEM TO BE SOLVED: To provide an attachment structure which can reduce a possibility that an attachment part is unintentionally removed by any external factor, and can prevent that the removal of the attachment part becomes difficult due to the rigid attachment of the attachment part by the further application of a force in an attached direction.SOLUTION: An attachment structure comprises a lower face material 20 having a bulkhead 10b, and a marker 8 having a claw part 80 which can be fixed to the bulkhead 10b. When the marker 8 is in a fixed state when being attached to the lower face material 20, the removal of the marker 8 along a vertical direction is impossible, when the marker is in a fixation-released state, the removal of the marker 8 along the vertical direction is possible, and when a force to the fixation release direction which is different from the vertical direction acts on the marker 8, a mutual state of the bulkhead 10b and the claw part 80 is switched to the fixation release state from the fixed state.SELECTED DRAWING: Figure 15COPYRIGHT: (C)2018,JPO&INPIT【課題】取付部が、何等かの外的要因により不本意に取り外されてしまう可能性を低減できると共に、取り付けた向きにさらに力が作用して取付部が強固に取り付けられてしまうことにより、取付部の取り外しが困難となってしまうことを防止できる取付構造を提供すること。【解決手段】取付構造は、隔壁10bを有する下面材20と、隔壁10bと相互に固定可能な爪部80を有するマーカー8と、を備え、マーカー8が下面材20に取り付けられている状態において、固定状態の場合には、上下方向に沿ってマーカー8の取り外しが不可能であり、固定解除状態の場合には、上下方向に沿ってマーカー8の取り外しが可能であり、マーカー8に対して、上下方向とは異なる固定解除方向への力が作用した際には、隔壁10b及び爪部80の相互の状態は、固定状態から固定解除状態に切り換わる。【選択図】図15
