Document Type and Number:
WIPO Patent Application WO/2022/176667
Kind Code:
A1
Abstract:
In the present invention, a reducer (1) comprises: an input shaft (10) that rotates about a rotational axis (O1); an internally toothed gear (20) that is disposed about an eccentric axis (O2), that operates in association with rotation of the input shaft (10), and that has a plurality of internal teeth (21) and a guiding member (30) protruding in a first direction of the axial direction; an externally toothed gear (40) that is disposed in a second direction of the axial direction in relation to the internally toothed gear (20), that is capable of rotating about the rotational axis (O1), and that has a plurality of external teeth (41); an output shaft (50) that rotates about the rotational axis (O1) in association with rotation of the externally toothed gear (40); and a lower case (65) disposed in the first direction of the axial direction in relation to the internally toothed gear (20). Formed in the lower case (65) is an accommodating recess (67) that restrains the rotation of the internally toothed gear (20) and that receives the guiding member (30) so as to allow the internally toothed gear (20) to eccentrically swing around the rotational axis (O1).
