A, 10A. The multi-row tapered roller bearing 10A is composed of a single-row outer ring coaxially arranged with a double-row inner ring 35 and an outer ring spacer 39.
Each of the rolling members 33 is disposed along the inner raceway 36 and the outer raceway 41. In such a multi-row tapered roller bearing structure 10, the multi-row tapered roller bearings 10A coaxially arranged via the inner ring spacer 34 and the spacer 11 are positioned by the fixing member 14 with respect to the housing 43. The multi-row tapered roller bearing structure 10 includes, according to the present invention, pressing means 12A, 12B for pressing the single-row outer rings 38, 38 in the respective multi-row tapered roller bearings 10A in directions approaching each other.

Thus, an appropriate preload is applied to all the rolling members 33 in each row. The outer race spacer 39 interposed between the single-row outer races 38, 38 is not normally used in a double-row bearing, but in the present invention, the rolling member 33 is excessively large with respect to the inner raceway 36 and the outer raceway 41. By appropriately selecting the thickness dimension (dimension in the horizontal direction in the figure) in advance so that a load is not applied, a preload adjusting means is provided when the single row outer ring 38 is positioned on the housing 43 by the fixing member 14. . Further, when the axial force acts on the bearing, the force can be received in only one row at the end without the spacer, whereas the force can be received in two rows by the outer ring spacer 39. as a result,
Damage due to large axial forces can also be avoided.

Since the pressing means 12 for pressing the pressing means 12 in a direction approaching each other is provided, the pressing force of the pressing means 12 is appropriately set, and the thickness dimension of each spacer 39 is appropriately selected, whereby each rolling is performed. The member 33 is brought into contact with the inner raceway 36 and the outer raceway 41 with an appropriate pressure. Therefore, according to the multi-row tapered roller bearing structure 10, the possibility that the rolling member 33, the inner raceway 36, and the outer raceway 41 are damaged can be reduced as compared with the related art.
