An Oldham ring (1), provided respectively on a first end surface (101) and a second end surface (102) thereof with a first sliding block (13) and a second sliding block (19). A first mounting position (133) is provided on the first sliding block (13), a first roller set (14) is provided in the first mounting position (133), and the first roller set (14) comprises multiple first rollers (141) arranged in a first movement direction, and/or, a second mounting position is provided on the second sliding block (19), a second roller set (18) is provided in the second mounting position, and the second roller set (18) comprises multiple second rollers (181) arranged in a second movement direction. The first sliding block (13) is rollingly friction-fitted with a first groove surface of a first sliding groove (23) of an input element (2); the second sliding block (19) is rollingly friction-fitted with a second groove surface of a second sliding groove (32) of an output element (3). The employment of rolling friction fit in place of an existing rolling friction fit reduces the degree of wear and extends service life.
