Abstract
A spacer is inserted into a space between an existing pipe and a rehabilitating pipe to adjust a position of the rehabilitating pipe with respect to the existing pipe. The spacer has an elongated shape with both end portions in a longitudinal direction thereof cut off at an oblique angle and has a transverse width increasing gradually from an upper surface portion to a bottom surface portion. A space is formed in the bottom surface portion to correspond to a shape of the upper surface portion, thereby allowing a number of the spacers to be stacked on one another in a thickness direction thereof. The upper surface portion has a flat-plate shape with a flat rectangular surface region.
