Provided is a compact reducer device that has a main bearing with a relatively high moment rigidity. The reducer device is provided with a casing, an internal gear, an external gear, a second carrier member, and a main bearing (38). The main bearing (38) has an outer wheel (42) of the casing, an inner wheel (44) of the second carrier member, and taper rollers (46). In the taper rollers (46), a first taper roller and a second taper roller going around a surface other than the first taper roller are alternately disposed in the circumferential direction. At least a part of the engagement portion of the internal and external gears is positioned between a first crossing as the crossing of extension lines (L1, L2) on the same plane of a round surface (42b) of the first taper roller in the outer wheel (42) and a round surface (44a) of the first taper roller in the inner wheel (44) and a second crossing as the crossing of extension lines (L3, L4) on the same plane of a round surface (42a) of the ...
