<P>PROBLEM TO BE SOLVED: To obtain a structure having a loading cam device which is small in size, light in weight, easy in the securement of the efficiency of the face pressure of each traction part at starting, and also easy in the securement of sufficient durability. <P>SOLUTION: Intermediate rollers 19, 19 are constituted of two pairs of intermediate roller elements 21, 21 constituting axial piece half parts of the intermediate rollers 19, 19, respectively. Elastic members such as disc springs 22, 22 are sandwiched between the two pairs of intermediate roller elements 21, 21 at each intermediate roller 19, 19. Then, elastic forces in directions in which axial dimensions are increased are imparted to the intermediate rollers 19, 19, and a preload for securing the face pressure of a rolling contact part between and among peripheral faces of a sun roller 4a, an annular roller 5a, and the intermediate rollers 19, 19 is imparted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
