材とを別体に製作して両者を組立て、取外しすることは
できない。For this reason, it is possible to arrange a protective member around the outer circumference of the bellows, but with conventional bellows whose peaks are axially symmetrical, it is possible to deform the bellows between the bellows and the protective member so as not to impair its original performance. It is extremely difficult to provide a sufficient gap, and even if it were possible to use sheet metal, it would be impossible to manufacture the bellows and the protective member separately, assemble them, and then remove them.

The present invention relates to a spiral joint characterized in that a bellows protection ring is screwed onto the peak portion of a cylindrical bellows with a clearance.

グで保護するものである。(Function) The cylindrical bellows used in the spiral joint according to the present invention has a plurality of consecutive ridges spirally formed in the axial direction on its outer peripheral surface, so the spiral ridges are utilized. The protective ring is rotated and fitted to the outer circumferential surface of the bellows so that there is a clearance between the protective ring and the outer circumferential surface of the cylindrical bellows, and the bellows is protected by the protective ring.
また同保膜リングを円筒状ベローズよシ取外す場合には

しめることかできるものである。(Effects of the Invention) According to the present invention, a plurality of peaks are formed in a continuous spiral shape in the axial direction on the outer circumferential surface of the cylindrical bellows constituting the main body of the joint, and the outer circumferential surface of the bellows Leave a play space between the parts to allow the screws to be screwed together.
When a large load is applied, the bellows is prevented from being destroyed by the protective ring, and the clearance provided between the bellows and the protective ring allows the bellows to deform, absorbing the strain acting on the joint and allowing rotation. It is possible to reduce the force acting on the part.
