Abstract

PURPOSE:To make mechanism efficiency ever so better, by supporting a friction ball rolling element with a rolling friction mechanism, while pressing the friction rolling element to a friction surface being locked to both input and output shafts under pressure. CONSTITUTION:Each of friction ball rolling elements 8a and 8b is supported by a thrust bearing 5 and a bearing 10 in combination, while these rolling elements 8a and 8b are pressed against each of friction surfaces 16 and 14 being locked to both input and output shafts 1 and 17 by means of a pressure spring 30 and a plate spring 6 under pressure. With this constitution, since these friction ball rolling elements 8a and 8b are eventually pressed coherent to these friction surfaces 14 and 16 through a technique of rolling friction by the bearing 10 and the thrust bearing 5, any loss due to friction is as little as negligible and, what is more, there is no loss by force, thus mechanical efficiency comes yet better as a whole.
