PROBLEM TO BE SOLVED: To shorten a construction term by facilitating the joining of adjoining two members. SOLUTION: This joint integrally joins the adjoining two members 30 and 30 and is provided with a male joint 2 which is provided in one member 300 and has a fitting member 3 provided with serrated cross-sectional recesses/ projections 4 in the outer circumferential surface and a female joint 10 which is provided in the other member 30 and has a fitting object member 12 provided with recesses projections 13 to be mutually fitted with the recesses/projections 4 of the fitting member 3 of the male joint 2 in the internal circumferential surface. The female joint 10 is constituted movably in the orthogonal direction to the fitting direction with the male joint 2. The fitting object member 12 is divided into a plurality of pieces ts and pushed in the direction of contracting its diameter by a pushing member 13. The female joint 10 is enlarged inn fitting with the male joint 2 to allow the fitting with the male joint 2, and after the completion of the fitting, it is contracted, and retains the fitting state with the male joint 2.
