AI Technical Summary
Technical Problem
Existing control cables face challenges in achieving a thin diameter while maintaining sufficient breaking strength and elongation, leading to reduced abrasion resistance and durability, which compromises load efficiency.
Method used
An inner cable design featuring a core cable with an outer diameter of 2 mm or less, coated with a resin layer having a film thickness ratio of 2 to 20% and a melt flow rate of 1 to 50 g/10 min, and an outer casing with a 5 to 40% clearance, enhances load efficiency and abrasion resistance.
Benefits of technology
The design achieves excellent load efficiency, improved abrasion resistance, and enhanced productivity even with a small diameter, ensuring effective operation in light operating loads.

Abstract
The purpose of the present invention is to provide an inner cable that has excellent load efficiency even when small in diameter, and a control cable that comprises the inner cable. An inner cable 2 comprises a core cable 21 and a coat layer 22 that covers the core cable 21 and that is formed of a resin material. The diameter d2 of the outer periphery of the core cable 21 is 2 mm or less, the ratio of the film thickness t of the coat layer 22 to the radius r1 of the outer periphery of the inner cable 2 is 2‒20%, and the melt flow rate of the resin material is 1‒50 g per 10 minutes.
