Abstract: A rotating movable body for a wire rope includes a rotating portion through the interior of which a wire rope passes, the wire rope being formed by twisting together eight strands, and rotary plates provided on the rotating portion so as to engage with parts of the outer shape of the wire rope, wherein the rotary plates are arranged at a predetermined interval in the extension direction of the wire rope, and in a state where each of the plurality of strands is in contact with one of the rotary plates, the rotating portion moves in the extension direction of the wire rope and rotates so as to follow the twist of the strands.

Abstract: This invention concerns a coupling device including a detachable member 20 that can be attached to and detached from a grille, a first coupling member 21 and a second coupling member 22 provided on the detachable member 20, and a connecting member 23 provided on the detachable member 20 so as to connect the first coupling member 21 and the second coupling member 22, wherein the first coupling member 21 and the second coupling member 22 respectively include elongated holes, arc-shaped portions 51a, 51b provided on respective outer peripheral lower portions of the first coupling member 21 and the second coupling member 22, and semicircular arc portions that can be coupled to the grille, and the connecting member 23 includes a fixing shaft 24 that extends in a horizontal direction and is inserted into the respective elongated holes in the first coupling member 21 and the second coupling member 22.

Abstract: A vision guide with a light guiding rod including rope member formed by twisting plural strands; light guiding rod of circumferentially light emitting type being adheringly wound around spiral indentations formed between strands on outer circumference of rope member with core layer made of acrylic-based resin and clad layer made of fluorine-based resin; and light source attached to end portion of light guiding rod, wherein amount of change luminance of light guiding rod in test time over duration of 1000 hours by accelerated weathering tester is contained within range of ±10%; amount of change in each numerical value of chromaticity [x, y] is contained within range of ±0.02; flexural modulus of elasticity of light guiding rod under atmosphere of ?20 degrees Centigrade is contained at range of 0.5-5.0×103 MPa; rope member is formed by twisting strands at twisting angle from 10°-20°; and spiral indentations are uniformly formed with pitch from 100 mm-200 mm.

Abstract: Provided is a wire rope with resin wire, including a wire rope body in which a plurality of strands are twisted together, and at least one resin wire spirally wound around the wire rope body along a recess between the strands. Strand grooves into which the strands can fit and a resin wire groove into which the resin wire can fit are formed spirally along the twist of the wire rope with resin wire, in a winding hole of a resin wire winding die used for winding the resin wire around the wire rope body. As a result, the resin wire can be easily and reliably mounted on the wire rope body and a wire rope with resin wire can be thus produced.
