A practical cable made of a high strength fiber composite material is provided, which has high and stable strength, in addition, has even axial tension against bending and thus has a stable shape, and can be wound on a reel without shape deformation, and is hardly buckled when it is inserted into a hole or cylinder. The cable is formed by singly twisting a plurality of high strength fiber composite materials is used as a strand, and a plurality of the strands are twisted together at a twist angle of 2 to 12 degrees in a direction opposite to a twist direction of the strands, so that a double twist structure is made.

The invention claimed is: 1. A cable made of a high strength fiber composite material, comprising a plurality of strands each comprising a plurality of singly twisted high strength fiber composite materials including a wire of high-strength low-elasticity fiber impregnated with thermosetting synthetic resin, said plurality of single twisted strands being bundled, and twisted together at a twist angle of 2 to 12 degrees in a direction opposite to a twist direction of the strands, so that a double twist structure is made. 2. The cable made of the high strength fiber composite material according to claim 1: wherein the twist angle is 2 to 8 degrees. 3. The cable made of the high strength fiber composite material according to claim 1: wherein said plurality of strands are side strands, and wherein said cable has a core strand in the center, around which said plurality of side strands are disposed and twisted together. 4. The cable made of the high strength fiber composite material according to claim 3: wherein a synthetic resin base inclusion is disposed on the periphery of the core strand. 5. The cable made of the high strength fiber composite material according to claim 4: wherein the synthetic resin base inclusion is a covering layer applied on the periphery of the strand. 6. The cable made of the high strength fiber composite material according to claim 4: wherein the synthetic resin base inclusion is a filament member disposed in a gap between the core strand and the side strands. 7. The cable made of the high strength fiber composite material according to claim 1: wherein the cable does not have a strand in the center, and a plurality of strands are twisted together. 8. The cable made of the high strength fiber composite material according to claim 7: wherein a synthetic resin base inclusion is disposed in a central portion of the cable. 9. The cable made of the high strength fiber composite material according to claim 1: wherein the cable is formed in a process that a strand having a single twist structure with synthetic resin being uncured is fabricated through a layering step, lapping step, and primary closing step, then a plurality of the strands with uncured resin are twisted together into a cable in a secondary closing step, and finally the whole is cured in a curing step. 10. The cable made of the high strength fiber composite material according to claim 1: wherein the cable is formed in a process that a strand having a single twist structure with resin being cured is fabricated through a layering step, lapping step, primary closing step, and curing step, then a plurality of the strands with cured resin are twisted together into a cable in a secondary closing step. 11. The cable made of the high strength fiber composite material according to claim 3: wherein the cable is formed in a process that a single strand having a single twist structure with resin being cured is fabricated through a layering step, lapping step, primary closing step, and curing step, and separately from this, a plurality of strands having a single twist structure with resin being uncured are fabricated through a layering step, lapping step, and primary closing step, then the strand having the single twist structure with resin being cured is used as a core strand, around which the strands having the single twist structure with resin being uncured are disposed as side strands, and then the strands are twisted together into a cable in a secondary closing step, and finally the side strands with resin being uncured are cured in a curing step. 12. The cable made of the high strength fiber composite material according to claim 11: wherein the strand having the single twist structure with resin being cured includes a strand having synthetic resin base inclusion on a periphery.
