Claims

[Scope of utility model registration request]

A ratchet mechanism provided in the rotating drum biases a lever that can rotate step by step in only one direction with respect to the rotating drum in the direction in which it can rotate. By passing one end of the cable, which is wound around the outer periphery and allowed to run back and forth by being unwound around the outer periphery, through the rotating drum and fixed to the lever from the direction in which the lever cannot rotate. In the apparatus for absorbing the slackness of the cable, the ratchet mechanism is formed by ratchet teeth provided in the rotating drum and pawls provided on the lever and meshing step by step with the ratchet teeth. At the same time, the ratchet teeth, the pawl, and the lever are arranged in a direction that allows the lever to rotate slightly when the pawl fully meshes with the engagement surface of the ratchet after the pawl advances one step at a time on the inclined surface of the ratchet tooth. A device for absorbing slack in a cable that rotates back and forth, characterized in that the cable rotates in the opposite direction.
