Abstract: The invention relates to a method for determining if a flexible joint means is out of alignment, i.e., if excess torque or pressure has caused malformation or malpositioning of the joint means. This is accomplished by incorporating a flexible leveling means onto a visible surface of the joint means. The leveling means has horizontal and vertical markings which permit simple visible inspection of the joint and a simple determination of the position and condition of the joint.

Abstract: 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 connection 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.
