ABSTRACT:
A hub unit is configured such that nitrogen gas, which functions as inert gas, is filled in a rolling element arranging space which is defined by an inner circumferential surface of an outer ring and an outer circumferential surface of a hub body for arranging rolling elements therein in such a manner as to be sealed therein in a semi-hermetically closed state by a seal member and a cover, so as to prevent the nitrogen gas from flowing out to an exterior space. The seal member, which is provided at an end portion of the rolling element arranging space which end lies on a vehicle-outer side, is formed as an elastic seal element, and is fixed to the outer ring at one end whereas being secured to the hub body at the other end thereof while being elastically deformed, whereby the seal member has a function to prevent the intrusion of water from the exterior space into the rolling element arranging space. This seal member prevents the inert gas filled in the rolling element arranging space from flowing out to the outside.
