To provide an apparatus for holding a tubular matter, which can hold easily a flexible tubular matter 10 made of a resin or a metal at the coaxial position relative to a core material 14 even under variation in its diameters.

The apparatus comprises a core material 14 set forth coaxially in a tubular matter 10 to be held, an inner coil spring 11 and an outer coil spring 12 set forth under fitting in a space between the core material 14 and the tubular matter 10 and a pressing means for pressing the coil springs 11 and 12 along the axial direction of the core material 14. When the coil springs 11 and 12 set forth under fitting are pressed along the axial direction of the core material 14, the adhering surfaces are pressed with each other so as to move the outer coil spring 12 toward the direction of the diameter.
