Abstract
An expansion tube joint of the present invention comprises a first cylindrical body, a second cylindrical body inserted along an axis of the first cylindrical body, a seal member mounted between the first and second cylindrical bodies closer to an insertion port of the first cylindrical body, a lock mechanism provided at a position deeper than the seal member for restricting a relative movement range along the axis of the first and second cylindrical bodies, and a coming-out preventing member for preventing the seal member from coming out from the insertion port of the first cylindrical body, wherein after a member constituting the lock mechanism is mounted, the seal member can be mounted.
