Title:
ROTATION TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/176687
Kind Code:
A1
Abstract:
A rotation transmission device with a holder (18) that has a pocket surface (24) capable of abutting on a roller (17) in the circumferential direction. The value of the arithmetic mean roughness (Ra) of the pocket surface (24) is equal to or less than the value of the arithmetic mean roughness (Ra) of the cylindrical surface (15) of an output-side member (2). Thus, when an input-side member (1) idles while the roller (17) is in a neutral position, the roller (17) pressed against the cylindrical surface (15) by centrifugal force is caused to rotate easily on its axis.
