受け部材722のボトムプレート722Aの所定位置には、図9に示すように、円形形状の貫通孔THが形成されている。この貫通孔THには、下方に大径部が位置すると共に、少なくとも小径部の下部に雄ねじが形成された段付形状の円柱部材732が上下動可能に貫通されている。また、円柱部材732の小径部であって、その大径部とボトムプレート722Aとの間に位置する雄ねじには、内周面に雌ねじが形成されたナット734が螺合されている。さらに、円柱部材732の小径部であって、ボトムプレート722Aから上方に突出する先端部には、V字レバー726の中央部が回転可能に固定されている。
受け部材722のボトムプレート722Aの所定位置には、円形形状の貫通孔THが形成されている。ボトムプレート722Aの下面であって、貫通孔THに対応する位置には、溶接ナット736が溶接されている。溶接ナット736には、六角穴付きボルト、六角ボルトなどのボルト738が下方から螺合されている。ボトムプレート722Aから上方に突出するボルト738の軸部には、少なくとも内周面に雌ねじが形成されたナット740が螺合されており、その周壁にV字レバー726の中央部が回転可能に固定されている。
