The above-mentioned drive cord has a core material disposed in the center, a synthetic resin envelope material enclosing the core material, and a rack tooth is formed on the core material, and a part of the core material is exposed outside in the tooth groove of the rack tooth. The exposed core material is composed of an aggregate of fibers knitted or twisted from a material that is more elastic and has higher strength than the foreskin material, and is embedded in the foreskin material at the same time as the foreskin material is extruded.
