PROBLEM TO BE SOLVED: To prevent the coming-off of a male joint from a female joint by employing a simple and robust joint structure. SOLUTION: A between-rings joint comprises: the female joint 10 with an approximately cylindrical fitting body 12, which is provided on a female joint surface 10a; the male joint 20 with a pin 22 for being inserted through the fitting body 12, which is provided on a male joint surface 20a; a locking ring member 30 which is arranged in such a manner as to be fitted into the outer peripheral surface 12a of the fitting body 12; and a push-in ring member 40 which moves the locking ring member 30 in an insertion direction E along with the insertion of the pin 22. As the pin 22 is inserted into the fitting body 12 so that the locking ring member 30 can be moved in the insertion direction E, the fitting body 12 is moved to a radial inside so as to fasten and fix a peripheral portion of the pin 22.
