摘要： PROBLEM TO BE SOLVED: To provide a roller bearing device which is easily manufactured and assembled, is small-sized and inexpensive, and effectively distributes preload in the axial direction on an inner side ring.SOLUTION: A roller bearing device includes an inner ring 3, an outer ring 2 and two sets of rolling members 4, 5 which are arranged between tracks 9, 13, 10, 14 formed on the inner ring and the outer ring 2, 3. Therein, the rolling member 4 includes at least one roller 6 capable of enduring a stress in the axial direction, the rolling member 5 includes an angular contact roller 8 capable of enduring both of a stress in the radial direction and the stress in the axial direction, and the inner ring and the outer ring 3, 2 are coaxial to a rotation axis X-X of a roller bearing 1. The roller 6 includes a first swing axis Y-Yinclined at a first angle αof 45-95° with respect to the rotation axis X-X and the roller 8 includes a second swing axis Y-Yinclined at a second angle αof 0-45° with respect to the rotation axis X-X.
