Abstract
A flexible transmission device utilizes two flexible cables or ropes to pass through a narrow passage and connect two operating elements. An extendable mechanism is an intermediate of the two flexible elements. The extendable mechanism includes two tubes co-axially linked to each other. The two flexible elements overlap in the extendable mechanism in a free moving condition, which allows the relative distance between the two operating elements changing. When a flexible element is pulled from an operating member, a slider connected between the two flexible elements will be biased to fasten the two flexible elements so that the drag force can be transmitted to the second operating member.
