PROBLEM TO BE SOLVED: To provide a nest building prevention material fitting attachment for attaching a nest building prevention material on a lid of a pole transformer in an easily detachable manner.SOLUTION: A nest building prevention material fitting attachment 1A to be detachably attached to an annular tool 11 protrusively provided on a lid fixture 10 of a pole transformer 7 includes: a first holding part 2 for detachably holding the annular tool 11 and a second holding part 5 attached in a state that the direction of an opening 6a is reversed with respect to the first holding part 2 for detachably holding a horizontal material 13a of a nest building prevention material. The first holding part 2 includes: a first holding leaf spring 3 made of a flat plate material with a C- or U-shaped cross section and at least one protrusion 4 that is provided on an inside surface 3a in a protruding manner. The second holding part 5 is composed of a second holding leaf spring 6 made of a flat plate material with a C- or U-shaped cross section. When the annular tool 11 is held by the first holding part 2, the protrusion 4 enters a hole 12 of the annular tool 11, thereby forming a fitting structure with the annular tool 11.COPYRIGHT: (C)2015,JPO&INPIT【課題】柱上変圧器の蓋上に営巣防止材を着脱容易に取設するための営巣防止材取付けアタッチメントを提供する。【解決手段】柱上変圧器7の蓋固定具10上に突設される環状具11に着脱可能に装着される営巣防止材取付けアタッチメント1Aであって、環状具11を着脱可能に挟持する第1の挟持部2と、第1の挟持部2に対して開口部6aの向きが逆転した状態で取設され、営巣防止材の水平材13aを着脱可能に挟持する第2の挟持部5と、を有し、第1の挟持部2は、断面コ又はU字形の平板材からなる第1の挟持用板バネ3と、その内側面3a上に突設される少なくとも1つの突起4とを具備し、第2の挟持部5は、断面コ又はU字形の平板材からなる第2の挟持用板バネ6からなり、環状具11を第1の挟持部2で挟持した際に、突起4は環状具11の孔12に侵入して環状具11と嵌合構造を形成することを特徴とする営巣防止材取付けアタッチメント1Aによる。【選択図】図2
