Zusammenfassung:	Even if machining textures remain on the surface in contact with a sealing lip, the deterioration of sealing performance is suppressed, and the disorder of the rotation torque of an inner peripheral side member and the generation of abnormal noise are suppressed at the same time. Selecting a lip reaction force (F)/hub diameter (D) and a lip surface roughness (R) included in the design region; the design region is a preset lip reaction force (F)/hub diameter (D) based on a value obtained by dividing a value of a reaction force (F) of a side lip (30) in use by a value of a hub diameter (D) of a diameter of a hub (52) (lip reaction force (F)/hub diameter (D)), and a value of a surface roughness of a sealing surface (31) of the side lip (30), namely a lip surface roughness (R). The hub seal is designed so that the lip reaction force (F)/hub diameter (D) and the lip surface roughness (R) become the selected lip reaction force (F)/hub diameter (D) and lip surface roughness (R), and the hub seal is manufactured so a
