Abstract

PURPOSE: To reliably exhaust intruded water and dust by providing exhaust holes in seal sections of the bearing and below the outer sides of the seal sections.
CONSTITUTION: Slingers 14 having surface S are fitted on and secured to the outer periphery of projected ring portions 12 of inner rings 5a. Within projected ring portions 13 of outer rings 5b seal members 15 having a shape opposing the slingers 14 are fitted and secured. Seal bodies 6 of the seal members 15 are in frictional contact with the surface 13. On the axially outer sides of the seal bodies 6 spaces 7 are defined by inner rings 5a, outer rings 5b, the inner surface of a front lid body 2 and a rib 17 thereof and the inner surface of a flange 21 of an inner ring retainer ring 18, and on the lower side exhaust holes 8 are provided. Water and dust intruded into the seal sections 3 are reliably exhausted from the spaces 7 through the exhaust holes 8.
