| 1. A bearing sealing device for sealing a bearing member which is interposed between a first member and a second member and
allows relative rotation between the first member and the second member, wherein the first member is located radially outward
of the bearing member and the second member is located radially inward of the bearing member, comprising:
a seal washer comprising:
a metallic washer located adjacent to the first member and the second member; and
a resilient seal fixed to an inner periphery of the washer and interposed between the first member and the second member for
sealing the bearing member to form a sealed space between the seal and the bearing member, the seal having a first seal element
which is normally in contact with one of member surfaces of the first member and the bearing member, wherein the first seal
element is bendable outward only by increased pressure in the space, wherein an outer periphery of the washer is in contact
with an end face of the first member, which helps to prevent foreign matter from entering into the space.
