PURPOSE:To make the extent of transmission force larger as well as to prolong a span of service life in each of constituent parts, by attaching plural pieces of spherical bodies tightly to one side of a power transmission part at intervals, and setting up an elastic member and a driven power transmission member, installing a weighting member in the upper part, on this upper part via lubricating oil. CONSTITUTION:Plural metal spherical bodies 2 of 1mm in each diameter are tightly attached to an upper surface of a power trnamission member 1 of metallic material by means of welding device such as brazing or the like at some intervals. And, an elastic member 4 of an oilproof rubber material such as fluoro rubber or the like is set up on an upper part of these spherical bodies 2, while engine oil 5 is interposed between this elastic member and the power transmission part 1 and a driven power transmission member 6 and a weighting member 7 are set up on an upper part of the elastic member 4. Here, when weighting F is added to the driven power transmission member 6 and the elastic member 4 by the weighting member 7 and force in an arrow A direction is added to the power transmission member 1, a contact state between the front of each spherical body 2 and the elastic member 4 grows larger. Therefore, large transfer force is secured with a small load, thus service life in each of constituent parts is prolongable.
