PROBLEM TO BE SOLVED: To prevent damage on an eccentric rocking type gear device due to an influence of a radial load while suppressing an increase in a parts count and a complicated structure. SOLUTION: The eccentric rocking type gear device 1 includes carrier bearings 6, 7 rotatably supporting a carrier 4 in an outer cylinder 2. The carrier bearings 6, 7 includes inner ring parts 6a, 7a rotatable integrally with the carrier 4, outer ring parts 6b, 7b rotatable integrally with the outer cylinder 2, and rolling members 6c, 7c rollably arranged between the inner ring parts 6a, 7a and outer ring parts 6b, 7b. Clearances allowing the rolling members 6c, 7c to be displaced in a radial direction of the outer cylinder 2 are formed between the inner ring parts 6a, 7a and outer ring parts 6b, 7b.
