Claims

[Claims for Utility Model Registration] (1) A rolling element is provided between an outer member having an inner raceway serving as a rotating side and an inner member having an outer raceway serving as a stationary side, and the inner member having: It has a track-side cylindrical part having an outer raceway, and a fixing shaft part having a smaller diameter and extending in the axial direction on one end side of the cylindrical part, and an outer member and an inner member on the shaft part side. A rolling bearing with a shaft comprising: a ring-shaped seal body for sealing between the inner member and the outer member; The lid-shaped seal body has an outer peripheral part fixed to the outer member and a flat part corresponding to the end face of the inner member, and the connecting part between the flat part and the outer peripheral part is flexible enough to be elastically deformable in the axial direction. A rolling bearing with a shaft. (2) A rolling bearing with a shaft according to claim 1 of the utility model registration claim, in which the inner member is formed from one member. (3) Scope of claims for utility model registration, paragraph 1 or 2
In the shaft-equipped rolling bearing described in paragraph 1, the lid-shaped seal body is mainly made of an elastic body and has a reinforcing core metal, and
The core metals are each provided independently with a flexible portion as a boundary. (4) Scope of claims for utility model registration, paragraphs 1 to 3
In the shaft-equipped rolling bearing according to any one of Items 1 to 3, a sealing portion is formed between the inner peripheral edge of the outer peripheral portion of the lid-shaped seal body and the outer peripheral surface of the cylindrical portion of the inner member.
