PROBLEM TO BE SOLVED: To provide a continuously variable transmission mechanism enhancing inner diameter accuracy of a support hole of a journal support member and improving support rigidity, and capable of suppressing influence on an eccentric amount of an eccentric disk.SOLUTION: First and second crank pins 16c-16h, 17c-17h are respectively provided so that a projection portion N1 where the first and second crank pins 16c-16h, 17c-17h are projected along an axial direction is positioned in contours N2 of first and second crank journals 16p-16v, 17p-17v to which the first and second crank pins 16c-16h, 17c-17h are connected. First and second crank journals 16q-16u, 17q-17u respectively have first and second support holes 52a, 52b supporting the first and second crank journals 16q-16u, 17q-17u, and are rotatably supported to a journal support member 52 constituted with a single member. Also, the journal support member 52 is rotatably supported by a mission case 160 through a bearing 105.SELECTED DRAWING: Figure 16 |
