Claims (1)
えながら少しずつ回転せしめる穿孔装置において
、上記ロツドを取囲むように崩壊防止用ケーシン
グを穿孔装置本体に回転自在に取付け、該ケーシ
ングとロツドとの間に回転力伝達用コマを介挿さ
せて、上記ロツドの回転をケーシングに伝達せし
めるようにしたことを特徴とする穿孔装置。 In a drilling device that rotates a rod having a drilling bit at its tip little by little while applying an impact, a collapse-preventing casing is rotatably attached to the drilling device body so as to surround the rod, and a casing is installed between the casing and the rod. A drilling device characterized in that a rotating force transmitting piece is inserted to transmit the rotation of the rod to the casing.
