PROBLEM TO BE SOLVED: To provide a shaft joining device to axially for connecting two tubular parts. SOLUTION: The shaft joining device for axially coupling two tubular parts has an end part provided with a radial flange which includes a connecting device which fastens two flanges tightly so that the two flanges are fixed surely, and loads are applied to the two flanges in the direction of each other. A sealing device, to which large thermal load can be applied, is arranged between the two flanges. The connecting device has at least one sheet metal strap made of a high-elastic material. The sheet material strap extends in at least major part of the circumference of the flange and has an axial outside margin providing a tooth. Since the tooth has an end which is curved inwardly at an angel of 90 degree or more, and which juts out inwardly in the radial direction, fastening the flange by the connecting device allows the tooth to apply axial load to the sealing device, while being supported by the side face of the flange, which is opposed to the end jutting out inward in the radial direction, in a state of applying a stress previously.
