- ブラシ材の基部を断面U字形のブラシ挟着具で挟着保持してシールブラシを形成し、該シールブラシのブラシ材をばね板から成る外側保護板と内側保護板で挟み、該シールブラシの基部と内外側保護板の基部とを断面U字形のブラシホルダー内に加圧保持し、該U字形ブラシホルダーをトンネル掘削機のテール部内周面に取り付け、U字形ブラシホルダーから延出された上記ブラシ材の先端部を上記外側保護板の弾力にて上記テール部から押し出されるトンネル構築用埋設管の外周面に加圧接触してテールシールを図る構成としたトンネル掘削機におけるテールシールブラシにおいて、上記U字形ブラシ挟着具の側板口縁部と対向する上記U字形ブラシホルダーの内面に細長の平板から成る押え板を溶接にて取り付け、該押え板の基部側エッジを上記U字形ブラシ挟着具の側板の口縁部の外側面に加圧接触するよう配設し、該基部側エッジの加圧接触により同挟着具の側板口縁部を縮閉方向へ加圧する押え力を得ると共に、該基部側エッジの加圧接触により上記シールブラシの引き抜き力に対する制動力を得る構成としたことを特徴とするトンネル掘削機におけるテールシールブラシ。
