Abstract
A hub seal seals a gap between an outer race member and an inner race member of a hub bearing. The hub seal includes: an annular base; and a seal member attached to the base and including an annular elastic material. The seal member includes a side lip extending toward an outer side and an intermediate lip extending toward the outer side on an inner periphery side relative to the side lip. A sliding surface of the side lip that comes into contact to seal the gap between the outer race member and the inner race member is rougher than a sliding surface of the intermediate lip that comes into contact to seal the gap between the outer race member and the inner race member.
