摘要： A sealing structure with an annular pocket and a sealing device includes an annular pocket and a sealing device. The pocket is provided in a slinger, and the sealing device is attached to a housing of a differential device. The slinger is arranged on an output shaft of the differential device. A recessed part of the pocket is defined by an inner peripheral tubular portion, an outer peripheral tubular portion and a bottom portion of the slinger. The outer peripheral surface of the pocket is formed in the outer peripheral tubular portion of the slinger. The outer peripheral surface of the pocket increases in diameter toward the outside in an axis direction. A side lip of the sealing device extends in the outward direction, and an annular gap is formed between the side lip and the pocket.
