Abstract
A spacer for positioning a rehabilitating pipe has an elongated shape with both end portions in a longitudinal direction cut off at an angle. The spacer has a transverse width increasing gradually from an upper surface portion to a bottom surface portion and a space formed in the bottom surface portion to correspond to a shape of the upper surface portion, thereby allowing a plurality of the spacers to be stacked on one another in the thickness direction.
