〈効果〉
本考案は、以上の構成からなり、連結具本体、
押圧部材およびボルトの３部品からなり、部品点
数が少なくて済むので製造、組立がきわめて容易
に行える。<Effects> The present invention consists of the above-mentioned configuration, and includes a connector main body,
It consists of three parts: a pressing member and a bolt, and because the number of parts is small, manufacturing and assembly are extremely easy.
また、連結具本体と押圧部材が管体の内側に挿
入可能な大きさであるので、連結具自体が小型の
ものであり、資材節減が図れ、安価に提供するこ
とができる。 Furthermore, since the connector main body and the pressing member are large enough to be inserted into the inside of the tube, the connector itself is small, which saves on materials and can be provided at low cost.
管体の連結に際しては、予め連結具本体、押圧
