Abstract
A cage made of a resin includes: a small-diameter annular portion on one side in an axial direction; a large-diameter annular portion on the other side in the axial direction; and a plurality of column portions which link the small-diameter annular portion and the large-diameter annular portion to each other. Spaces which are formed between the large-diameter annular portion and the small-diameter annular portion and between the column portions adjacent to each other in the circumferential direction are pockets which hold the taper rollers. A surface of the entire cage including the small-diameter annular portion, the large-diameter annular portion, and all of the column portions is configured by aggregating a surface viewed from the one axial side and a surface viewed from the other axial side.
