The packing (1) according to the present invention is composed of a string-like body (4) in which a tape-like packing material (2) having at least one layer is folded in the thickness direction thereof in zigzags with mountain (3A) portions and valley (3B) portions alternately formed. According to the packing, the string-like body (4) cut into a predetermined length according to the diameter of a shaft (5) concerned may be wound on the outer peripheral surface of the shaft (5) with the width or thickness direction of the string-like body (4) directed in the radial direction of the shaft (5). Thus, the packing (1) is versatile with respect to the shaft diameter. The packing (1) itself produces no slip in the axial direction of a shaft (5) concerned. This prevents the packing (1) from protruding, thus eliminating the release of stress due to decrease in volume. The packing (1) is used with the string-like body (4) folded in the three-dimensional directions. Accordingly, the shaft-following properties of the packing (1) at the time when the same is worn, are satisfactory and the decrese in sealing properties is restrained. <IMAGE> |
