Abstract
In a conduit for a control cable, it is possible to ensure a good rigidity of a stranded portion 3A having a plurality of strand line elements 3 which are wound to an outer surface of the liner 2 without increasing a diameter (8.0 mm or less) of a conduit 1. In order to secure a greater polar moment of inertia of area, a combinatorial relationship between the number (N) of the strand line elements 3 and a diameter (.phi.) of the strand line element 3 is selected from the following group A, B and C. Where A:=.phi.=1.1.about.1.2 mm and N=13, B: .phi.=1.2.about.1.35 mm and N=12, C: .phi.=0.95.about.1.1 mm and N=14.
