Abstract

　製造の容易な構成によってツースとアダプタとの固定力を増大させることができるバケットのツース取付構造を提供する。バケットのツース取付構造では、弾性部材(７)が、アダプタ(３)の孔(３１)に挿入され、第１取付ピン(５)の雄ネジと第２取付ピン(６)の雌ネジとが螺合されることによって第１取付ピン(５)と第２取付ピン(７)とに挟まれて軸方向に圧縮され、径方向に膨張することによって孔(３１)の内壁面に密着する。また、アダプタ(３)の孔(３１)のうち弾性部材(７)と対向する部分は、孔(３１)の他の部分と同径であり、弾性部材(７)の少なくとも軸方向中間部分の外周面には周方向に沿って延びる凹部が設けられている。
