の可撓体を介装したことを特徴とするパツカー。 In a pump car that pressure-injects injection liquid into the ground from the bottom of a borehole, the piston is stopped by the rise of the piston between the cylinder body and a stopper fixed to the lower end of the piston rod, which also serves as a liquid supply pipe that penetrates the cylinder body of the piston cylinder. A packer characterized by interposing a thick cylindrical flexible body that bulges radially outward when pressed by a metal fitting and forms a partition between a piston rod and a borehole wall.
