Zusammenfassung:	PURPOSE: To obtain fixed sealing efficiency in a compact size by pressing an inner sealing ring onto a stepped portion of an axis at a sleeve section, and by positioning the sleeve section within an inner peripheral surface of an outer sealing. CONSTITUTION: A seal 10 comprises an outer sealing 11 and an inner sealing 12. An inner peripheral surface 16 of an outer sleeve 14 is firmly contacted to an outer peripheral surface 17 of a bearing bushing 1. An outer peripheral surface 20 of an inner sealing 12 is contacted to an inner peripheral surface 21 of an inner sleeve section 15 facing to an axis direction. A sleeve section 22 is concentrically positioned within the inner peripheral surface 21 of the outer sealing 11, and an expansion to a radial direction is prevented by the inner peripheral surface 21. Thereby the seal 10 is a compact size and is firmly disposed to the axis so fixed sealing efficiency can be obtained.
