TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a transmission system capable of reducing a price without swelling a general purpose plastic such as polypropylene while manifesting activities for suppressing an allophone and a rotating torque to the level equivalent to that of a conventionally used synthetic hydrocarbon-based grease. SOLUTION: This transmission system has a rotating body 2 and a fixed body 3 which mutually and relatively rotate, and a transmission body wound like a spring, and the rotating body 2 and the fixed body 3 are combined so as to freely and mutually slide. The transmission body is housed in a ring-like space formed in the interior by the rotating body 2 and the fixed body 3 so that the winding state may be freely tightened and loosened. The rotating body 2 and the fixed body 3 are coated with a polyglycol-based grease G at the sliding positions.
