Document Type and Number:
Japanese Patent JP2007247777
Kind Code:
A
Abstract:

To provide a dustproof mechanism while simplifying the construction of a conventional ball screw circulating component.

In the positioning and dustproof mechanism, a fitting ring groove is formed in the inner edge of a nut body adjacent to the circulating component, a fixing scraper constructed with a C-type retainer ring 31 is provided in the fitting ring groove, a soft cover layer 34 is applied on the outer edge of the retainer ring so as to be just fitted into the fitting ring groove of the nut body, and a spiral scrape part 35 is formed at the inner edge of the cover layer corresponding to a rolling screw groove of a ball screw. Thus, the fixing scraper fixes the circulating component to the nut body with the elastic operation of the soft cover layer. The spiral scrape part is utilized for scraping work for the rolling screw groove to enable dustproof operation.
