<p><P>PROBLEM TO BE SOLVED: To provide a buffer of a spiral hanger, and a spiral hanger installation structure, which prevent separation and damage on a connection part caused by excessive tension or impact in axial direction, without degrading attaching/detaching operability nor modifying it for enhancing a connection strength of the connection part between spiral hangers, relating to the spiral hanger wherein joint members fixed to both end parts are connected together to constitute a spiral connected body. <P>SOLUTION: The buffer 30 is arranged between a first joint member and a second joint member 20 fixed to both ends of a wire material 5 when a plurality of spiral hangers 3 including them. The buffer comprises a first connection member 31 having a connection part detachably connecting to the first joint member, a second connection member 41 having a connection part detachably connecting to the second joint member, and an elastic member 50 whose both ends are fixed with the first connection member and the second connection member respectively to expand/contract in the axial direction. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
