PROBLEM TO BE SOLVED: To reduce the number of partitems and reduce a cost. SOLUTION: In a sealing device 3 formed such that a guide ring 4 and an oil seal 5 are assembled together, the surface of the guide ring 4 between an outer ring body 1 and the guide ring 4 is covered with an elastic substance 6 to form structure for ensuring sealing ability and this structure eliminates an O-ring used in a conventional type. This constitution further reduces a parts cost and labor required for assembly compared with a conventional type. |
