<p>A connection structure for connection between piping (100) and a connection receiving body (10). The connection receiving body (10) has a joint member insertion hole (17) communicated with a fluid flow passage and into which one end of a joint member (50) is inserted, and also has a first flange (15) to which the joint member (50) is attached. The joint member (50) has a piping insertion hole (53) and a second flange (55) removably attached to the first flange (15) when the one end of the joint member (50) is inserted into the joint member insertion hole (17). The joint member (50) allows communication between the hollow part of the piping (100) inserted into the piping insertion hole (53) and the fluid flow passage of the connection receiving body (10). The joint member insertion hole (17) has a step (19) for preventing the piping (100), which is inserted into the piping insertion hole (53), from moving in the direction of insertion of the piping (100), a stopper member (30) placed closer to the joint member (50) than to the step part (19) and preventing the piping (100) from moving in the disconnection direction, and a seal member (40) placed closer to the joint member (50) than to the stopper member (30) and sealing between the piping and the inner peripheral surface of a wall defining the joint member insertion hole (17).</p> |
