Claims

[Scope of utility model registration request]

A tension spring 7 is housed in a spring housing tube 6 consisting of an outer tube 4 and an inner tube 5 slidably fitted to the outer tube 4 to form a horizontally expandable member 8. In addition, a plurality of pairs of links 1, 1 each having center portions C, C connected to each other in a swingable manner are arranged in the vertical direction, and an upper end portion 2 of the links 1, 1 is provided.
, 2 are swingably connected to the lower end portions 9, 9 of the pair of links 1, 1 located above the links 1, 1 to form a vertically extendable link mechanism 3; The horizontally expandable member 8 is disposed between the links 1, 1, and the pair of links 1,
Upper end 2 or lower end 9 of one of the links 1
is swingably connected to the inner cylinder 5 and the upper end 2 or lower end 9 of the other link 1 to the outer cylinder 4, respectively, so that the upper end 2 or 2 of the pair of links 1, 1 or A clothesline characterized in that lower end portions 9, 9 are resiliently biased so as to constantly draw each other in inward directions A, A.
