Kind Code:
A1
Abstract:
A shell outer ring (11) includes a cylindrical outer ring body (12), flanges (14) protruding radially inward from both axial ends of the outer ring main body (12), and a rounded portion (16) that joins the outer ring body (12) and the flanges (14) and has a rounded bulging surface on the outer surface. The outer peripheral surface of the outer ring body (12) on the axially outer side is formed into a tapered surface (17) that gradually decreases in diameter toward the axially outer side. The tapered surface (17) smoothly connects with the bulging surface of the rounded portion (16). Regarding a cut surface made by cutting the shell outer ring (11) at a plane including the center axis of the shell outer ring (11), a virtual circle (16c) that overlaps the cross-sectional line of the bulging surface is located on the inner diameter side of the cross-sectional line of the tapered surface (17).
