PURPOSE: To prevent that a cable send-out force is dropped due to an increase in the weight of a cable by installing a guide shoe which guides a chain for an endless belt for driving use on a definite track so as to always come into contact with the chain.

CONSTITUTION: An endless belt 20 for driving use constitutes a loop by being connected by a plurality of chains 23-1 to 23-3 arranged at equal intervals in parallel with the lengthwise direction of a cable 1. Out of them, the chain 23-2 is arranged along the rear immediately near a part in close contact with the outer circumferential face of the cable 1 of the endless belt 20. The individual chains 23-1, 23-2, 23-3 are arranged so as to always come into contact with guide shoes 24-1, 24-2, 24-3 fixed respectively to a base stand 18, and they are guided smoothly on a definite track while a sufficient pressure force is applied. Thereby, it is possible to prevent that the send-out force of the cable 1 is dropped due to an increase in the weight of the cable 1.
