摘要

A flexible-shaft transmission, particularly for motor-vehicle tachometric instruments or like applications, including a metal cable (2) which is rotatable in a sheath (3) and connectible at respective ends to a rotary drive member and to a rotary driven member inserted in respective end connectors (4, 5) of the sheath. The sheath (3) is constituted by an inner tubular layer (7) of self-lubricating thermoplastics material and by an outer tubular layer (8) of thermoplastics rubber which is extruded on to the inner tubular layer (7) and glued thereto.
