PROBLEM TO BE SOLVED: To insert seal such as oil seal having a lip into a shaft without generating a part turned up of the lip. SOLUTION: Seal 10 is once inserted from the D cut part 14C of a shaft 14 to the end part of a cylindrical shaft body 14B and the seal 10 is advanced at a first speed (40mm/second, for instance) from the location up to a location where the seal 10 does not hit against a thick diameter part 14A of the shaft 14. At this time, the seal 10 is pulled out on the shaft body 14B from the location to the side of the D cut part 14C at a second speed (10mm/second, for instance) and is further inserted again from the location to an appropriate location at a third speed (70mm/second, for instance) becomes a possibility that the lip 10A of the seal 10 is completely turned up is high. The operations at these second speed and third speed are performed one time or a plural number of times. At the time of the last insertion of the seal 10, the seal 10 is located at a prescribed insertion location. |
