摘要： An expansion joint device, wherein both ends of an axially extendable bellows type outer tube (31) are connected liquid-tightly to a pair of connecting path end parts (20) so as to form an extendable path part (30), a tube-shaped resin film (33) not allowing fluid to pass is disposed on the internal surface of the bellows type outer tube (31), both axial end parts of that film are connected liquid-tightly to the connecting path end parts, and a tube-shaped part (34) located at the intermediate part of the tube-shaped resin film (33) covers liquid-tightly the inner surface of the bellows type outer tube (31), whereby it is prevented that the fluid flowing through the inside or foreign matter contained in the fluid remains in the inner peripheral surface recessed part of the bellows type outer tube (31) so as to ensure the sanitation and quality maintainability of the expansion joint device and, in addition to or instead of the bellows type outer tube (31), the inside and outside sleeves are overlapped slidably with each other so as to also form an expansion outer tube.

摘要： Both ends of a bellows-type outer cylinder 31 capable of axial expansion and contraction are connected in a leakproof manner to a pair of connecting passage ends 20, thereby constituting an expansion passage 30. A cylindrical resin film 33 having no permeability to fluid is arranged in an interior of the bellows-type outer cylinder 31, and the axial ends thereof are connected in a leakproof manner to said connecting passage end regions. The cylindrical region 34 positioned in the intermediate region of the cylindrical resin film 33 covers the inner surface of said bellows-type outer cylinder 31 in a leakproof manner.
According to such structure, the fluid traveling through said bellows-type outer cylinder 31 and the impurities contained in the fluid are prevented from residing in the grooves formed to the inner circumferential surface of the bellows-type outer cylinder 31, and the cleanness and quality maintaining property of the expansion joint device is secured. In another example, further added to or instead of said bellows-type outer cylinder 31, an inner sleeve and an outer sleeve may be slidably superposed to form an expansion outer cylinder.
