PROBLEM TO BE SOLVED: To provide a coupling member, a falling prevention member, and a bird damage prevention tool, which can be simply coupled even when a worker wears a pair of rubber gloves for preventing electric shock, and can be prevented from coming off due to torsion.SOLUTION: A bird damage prevention tool 1 is formed by coupling a plurality of coupling members 3. In this bird damage prevention tool 1, when coupling the adjoining coupling members 3 through the insertion holes 30a of which a cable is passed, while holding the support part 33 of one coupling member 3 between a forefinger and a middle finger, a thumb is hooked over the pedestal part 32 of the other coupling part 3, and if the forefinger and the middle finger are brought close to the thumb, a protruding part 35 hits the pedestal part 32, and the tip of the protruding part 35 drops into an anti-loosening hole part 36. Then, if the thumb, the forefinger, and the middle finger are pushed from both sides so that the pedestal part 32 and a mounting piece part 34 are brought close to each other, the protruding part 35 is inserted into the anti-loosening hole 36 and is left as it is so as not to be pulled out. Therefore, the coupling members can be simply coupled to each other even if the worker wears a pair of rubber gloves.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】作業員が感電防止用のゴム手袋を付けている場合でも簡単に連結すること、また、ネジレからくる外れを防止ができる連結部材、脱落防止部材、及び、鳥害防止具を提供する。【解決手段】鳥害防止具1は複数の連結部材3を連結してなる。この鳥害防止具1では、挿通孔30aに電線が通された隣り合う連結部材3を連結する場合、一方の連結部材3の支柱部33を人差指と中指とで挟みながら、他方の連結部材3の台座部32に親指を引っ掛け、人差指及び中指を親指に近づけると、突起部35が台座部32に当たって、突起部35の先端が抜止孔部36に落ちる。そしてこのとき親指と、人差指及び中指とを、台座部32及び取付片部34が互いに近づくように両側から押すと、突起部35が抜止孔部36に挿入されてそのまま抜けなくなる。そのため、この連結部材は、ゴム手袋をしていても簡単に連結することができる。【選択図】図2
