Document Type and Number:
WIPO Patent Application WO/2022/202526
Kind Code:
A1
Abstract:
Each of column portions (31) of a resin cage (3) has: roller guide surfaces (40) for guiding rollers; outer-diameter-side recessed portions (32) which are recessed from the roller guide surfaces in the circumferential direction and each of which extends from the outer diameter toward the inner diameter partway to a position in the radial direction; and inner-diameter-side recessed portions (35) which are recessed from the roller guide surfaces in the circumferential direction and which continuously extend from the outer-diameter-side recessed portions to the inner diameter side. Assuming that a distance between the outer-diameter-side recessed portions of the column portions facing each other across a pocket portion (50) defined between the column portions adjacent to each other in the circumferential direction is represented by W1 and a distance between the inner-diameter-side recessed portions of the column portions facing each other across the pocket portion is represented by W2, a relationship of W1>W2 is established.
