PROBLEM TO BE SOLVED: To provide a net locking member that enables a net for prevention of intrusion of small animals to be easily fixed by an operation performed from one side of a fence by one person, when the net is fixed by fixing means in the state of being annexed to a fence surface.SOLUTION: A net locking member includes: an approximately U-shaped locking piece 2 that is locked to peripheral edges 51a and 61a of both of openings communicating with each other an extension piece 4 that is elongated from one end of the locking piece and that is provided with a plurality of high-frictional-resistance parts 6 along a longitudinal direction and a stopper piece 10 that has a stopper hole part 11 provided with a check structure inhibiting return by being engaged with the high-frictional-resistance parts when the extension piece is inserted from its end. The locking piece has a folded part 2a that is inserted into each opening to be capable of passing to an opposite surface side and that can be locked to the peripheral edge of each opening when pulled back.COPYRIGHT: (C)2012,JPO&INPIT【課題】小動物侵入防止用のネットをフェンス面に添設した状態で固定手段を用いて固定する際に、フェンスの片側からの一人による作業によって容易に固定できる。【解決手段】連通した両開口部の周縁部51a、61aに係止される略U字状の係止片2と、係止片の一端から延び且つ長手方向に沿って複数の高摩擦抵抗部6を備えた延長片4と、延長片をその端部から挿入したときに該高摩擦抵抗部と係合して逆戻りを禁止する逆止構造のストッパ穴部11を有したストッパ片10と、を備え、係止片は各開口部内に差込むことにより反対面側に通過可能であり、且つ引き戻した際に各開口部周縁に係止可能な折り返し部2aを有する。【選択図】図1
