Abstract

A hub seal (1) includes a seal main body (3) and a slinger (4). The seal main body (3) includes a reinforcement ring (10) and an elastic body portion (20). The slinger (4) includes a flange portion (31) and a tubular portion (32). An outer tubular surface (3a) as a tubular surface is formed in the seal main body (3). The elastic body portion (20) has a side lip (21) on an inner periphery side relative to the outer tubular surface (3a). The tubular portion (32) of the slinger (4) has a weir portion (33) which has an annular shape, is positioned on an outer periphery side relative to the side lip (21), and extends toward the outer periphery side, in an end portion on an inner side. The outer tubular surface (3a) faces, from the outer periphery side, the tubular portion (32). Between the outer tubular surface (3a) and an end (33a) of the weir portion (33), a first gap (S1) is formed whose width (W1) in a radial direction is narrower than a width (W2) of a second gap (S2) in the radial direction, the second gap (S2) being formed between the outer tubular surface (3a) and a portion which faces the outer tubular surface (3a) and is not the end (33a) of the weir portion (33).
