To provide technique for reduction of the degradation of friction force and furthermore for improvement of work efficiency.SOLUTION: The fastening structure is provided, which fastens first plate material and second plate material by a fastening member. The fastening member comprises: a bolt having a head portion on the side of one of the first plate material and the second plate material and penetrating through a first through-hole of the first plate material and a second through-hole of the second plate material; a nut to be threadedly engaged with the bolt from the side of the other; and an interposition member interposed between one of the head portion and the nut and the first plate material. The minimum outer diameter of one of the head portion and of the nut is smaller than the diameter of the first through-hole, and the outer diameter of the interposition member is larger than the diameter of the first through-hole.SELECTED DRAWING: Figure 3
【課題】摩擦力の低下を軽減させつつ、作業性を向上させる締結構造の技術を提供する。【解決手段】第１板材と第２板材とを締結部材で締結する締結構造であって、締結部材は、第１板材と第２板材の一方の側に頭部を有し、第１板材の第１貫通孔及び第２板材の第２貫通孔を貫通するボルトと、第１板材と第２板材の他方の側からボルトに螺合するナットと、頭部とナットの一方と第１板材との間に介装された介装部材と、を備え、頭部とナットの一方の最小外径は、第１貫通孔より狭径であり、介装部材の外径は、第１貫通孔より広径であることを特徴とする締結構造である。【選択図】図３
