In a sealing device for a deep groove ball bearing that labyrinth-seals the inside of the bearing in close proximity to each other, the tip of the shield plate connects the outer circumferential surface or both end circumferential surfaces of the inner circumferential surface of the other raceway to which the tip portion of the shield plate adjoins the circumferential surface. A first sealing device for a deep groove ball bearing, characterized in that a slope is formed on a slope constituting a labyrinth gap between the shield plate and the tip of the shield plate.
