PROBLEM TO BE SOLVED: To provide a spacer device enabling an axial direction and an angular displacement to be attained between an inner ring and an outer ring and enabling an efficient spacing-apart action between the roller elements to be attained.SOLUTION: This invention is constituted in such a way that a toroidal roller bearing having an inner ring and an outer ring includes a spacer device 18 between the inner ring and the outer ring comprising a first roller element contact surface and a second roller element contact surface opposite to the first roller element contact surface; each of the first roller element contact surface and the second roller element contact surface has a concave shape to be formed to be coincident with a convex contact surface of each of roller elements 16a, 16b and 16c; the spacer device has protrusions extending from the first roller element contact surface and the second roller element contact surface outwardly; and there is provided a terminal member in which the protrusions extend at least partially over the ends of the two adjoining roller elements when the spacer device is being used.SELECTED DRAWING: Figure 7 |
