Provided is a cable including a stranded member floating-preventing element that can be easily peeled off.

A power transmission line core includes one core member and six side members twisted around the core member, each member obtained by impregnating a fiber bundle including a plurality of carbon fibers that are continuous in the longitudinal direction and bundled into the fiber bundle with a resin and curing the resin. A tow including a plurality of tow fibers that are continuous in the longitudinal direction and arranged flatly and densely is spirally wound around the surface of the power transmission line core in the direction opposite to the twisting direction of the side members. The tow is detachably entangled in the unevenness on the surface of the power transmission line core.

A wire rope having improved durability and that can be used in a medical device to be inserted into a patient's body. The wire rope includes a core wire and side wires. The core wire is a special metal element wire that has a hardness at an outer periphery in a cross-section thereof that is higher than that at a center in the cross-section thereof. The wire rope does not include grease.

A reinforcement strand (400) comprises a core (403) around which steel filaments (404) are twisted all with the same final lay length and direction. The steel filaments are arranged in an intermediate layer comprising N first steel filaments and an outer layer of 2N steel filaments circumferentially arranged around the intermediate layer. In the intermediate layer filaments will contact one another at a closing lay length that is determined by the number of steel filaments N in the intermediate layer, the diameter of the core and the diameter of the first steel filaments. By choosing the final lay length and direction equal to the between two and six times the closing lay length gaps will form between the intermediate layer filaments. The 2N outer layer filaments are further divided into a group of smaller (408) and a group of larger (406) diameter steel filaments.

A pneumatic radial tire includes belt layers disposed on an outer circumferential side of a carcass layer in a tread portion. The belt layers are formed of steel cords in a N+M structure in which the number of wire strands N of an inner layer is 2 to 4 and the number of wire strands M of an outer layer is 2 to 7. A twist direction of the inner layer is different from a twist direction of the outer layer. The steel cords are inclined with respect to a tire circumferential direction to intersect each other in layers of the belt layers. A belt cover layer disposed on an outer circumferential side of the belt layers is formed of organic fiber cords having elongation of 2.0% to 4.0% under 2.0 cN/dtex load. The organic fiber cords are wound spirally along the tire circumferential direction.

This steel cord for reinforcing a rubber article includes one core strand having a two-layer twisted layer structure formed by intertwining a plurality of steel filaments, and a plurality of sheath strands having a twisted layer structure formed by intertwining a plurality of steel filaments. The sheath strands are intertwined around the core strand, a core of the core strand is formed by two core filaments, and the diameter of outermost layer sheath filaments forming an outermost layer sheath of each sheath strand is greater than the diameter of filaments inside the outermost layer sheath of the sheath strand.
