Claims

[Scope of utility model registration request]

The outer ring has a cage guide flange bent in the axial direction on the outer periphery of the raceway made of annular steel plate, and the cage guide flange part is axially bent on the inner periphery of the raceway made of annular steel plate. In a thrust needle roller bearing in which needle rollers guided and held by a cage are disposed on at least one of a bent and formed inner ring, the inner circumferential direction of a flange portion of at least one of the outer ring and the inner ring. A notch is provided in the circumferential direction at at least two places with an appropriate interval between the notches and the end face of the flange portion, and a narrow connecting part is provided between the notches in the outer ring, and one of the circumferential ends of the notches in the outer ring is provided. The side connecting part has a claw that bends inward in the radial direction.
A claw portion bent radially outward is formed in a connecting portion on the other circumferential end side of at least one notch, and a claw portion bent radially outward is formed on the connecting portion on the other circumferential end side of the notch in the inner ring. A claw part that bends outward in the radial direction is formed in the connecting part, and a claw part that bends inward in the radial direction is formed in the connecting part on the other circumferential end side of at least one notch. Thrust needle roller bearing.
