ROLLING GUIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/239569
Kind Code:
A1
Abstract:
A rolling guide device 10 comprising: a track member 11; a moving member 21; and a plurality of rolling bodies 31, wherein, on opposite wall surfaces of a pair of wall portions 13 and 14 of the track member 11, rolling body-rolling surfaces 13a, 14a that are in contact with rolling body outer circumferential surfaces of the rolling bodies 31 are formed, a scraper 41 having a pressing portion 41c that presses the rolling body-rolling surfaces 13a, 14a is rotatably provided to the moving member 21, the scraper 41 includes at least an attachment portion 41a and the pressing portion 41c, and is formed such that frictional force of the pressing portion 41c with respect to the rolling body-rolling surfaces 13a,14a is smaller than that of the attachment portion 41a with respect to an attachment shaft 53 formed on the moving member 21. With such a configuration, the rolling guide device 10 allows the scraper 41 to exhibit the function thereof without interfering with the reciprocal linear movement of the moving member 21 relative to the track member 11 even when the moving member 21 is inclined in a rolling direction relative to the track member 11.
