PROBLEM TO BE SOLVED: To provide a lightweight toothed cable with excellent calmness without deteriorating operability and durability of conventional toothed dabbles using steel wire. SOLUTION: Fiber-reinforced resin composition having continuously spiral protrusion of resin attached to the surface in an axial direction of a rod comprising nonmetallic fibers coated and impregnated with a thermplastic resin is used for this toothed cable. Otherwise, the nonmetallic fibers are opened, thermplastic resin is impregnated between the fibers, and the continuously spiral resin protrusion is attached to the surface of it.
