Claims

[Scope of utility model registration request]

In a shaft seal in which lubricating oil that flows from the bearing to the slinger is sealed within a predetermined area of the bearing housing by a slinger provided on a rotating shaft, the bearing fits onto the inner circumferential wall of the bearing housing. a large diameter part that is larger than the outer diameter of the slinger and a small diameter part that is smaller in diameter than the large diameter part; forms an annular recess in which the inner circumferential wall of the large diameter portion extends toward the small diameter portion so that the outer circumferential surface of the slinger is located at a position opposite to the step; The outer circumferential surface of the slinger on the side of the slinger is brought close to the inner circumferential wall of the small diameter section, and the outer circumferential surface of the slinger on the side of the large diameter section is opened toward the large diameter section from the step. Shaft seal.
