PROBLEM TO BE SOLVED: To provide a new metallic cylinder joint equipped with a rubber ring, which eliminates difficulty and danger in work for driving a propeller pipe or the like into a lateral face hole at an extreme depth from the ground and connecting the pipe to the hole, ensures the pipe connection, and prevents breakage of the pipe. SOLUTION: The metallic cylinder joint equipped with the rubber ring is to be embedded in the lateral face hole formed in a concrete manhole, a culvert, or the like which is cast in situ, newly cast, or currently in use, as a joint for a connecting pipe such as the propeller pipe, in such cases of position correction of the manhole or the like. The metallic cylinder joint is formed by mounting a plurality of circular steel rings for bearing load of an inner face connecting pipe of a cylinder body of the metallic cylinder joint and for positioning and mounting the rubber ring, and fitting a base side of the rubber ring which is press-fitted to the connecting pipe such as the propeller pipe, into a gap between the circular steel rings, whereby the metallic cylinder joint is provided with the rubber ring.
