Abstract
In a connection structure of a tubular connection member and a joint member according to an embodiment, a joint member (20) with a cap nut (30) mounted thereon is connected to a tubular connection member (12) with a spiral ridge (14) and a flange (16). The cap nut (30) has a spiral groove formed in the inner peripheral surface and includes a detent member (35) having a movable portion (36) and an extending portion (37). A spigot portion of the joint member (20) is inserted into the tubular connection member (12), and the cap nut (30) is screwed in.
