1. A damper device comprising:
an input shaft member rotatable around a rotation axis such that a driving force of an internal combustion engine is input to the input shaft member;
an output shaft member rotatable around the rotation axis such that the driving force which was transmitted via the input shaft member, is output from the output shaft;
an input side cam and an output side cam arranged between the input shaft member and the output shaft member so as to respectively have opposing portions opposite each other in a rotation axis direction along the rotation axis, the input side cam and the output side cam respectively connected to the input shaft member and the output shaft member;
a damper bearing having an outer peripheral portion pivotable around a bearing axis on an opposing portion of one of the input side cam and the output side cam, the damper bearing arranged between the opposing portions of the input side cam and the output side cam in the rotation axis direction; and
an urging member urging the output side cam such that an opposing portion of the other of the input side cam and the output side cam abuts the outer peripheral portion of the damper bearing,
wherein a damper bearing assembly including a plurality of the damper bearings, is provided,
the damper bearing assembly has a bearing shaft supporting the plurality of damper bearings,
in the damper bearing assembly, bearing axes of the plurality of damper bearings are arranged along a bearing shaft axis extending in the longitudinal direction of the bearing shaft, and the plurality of damper bearings are arranged at intervals along the bearing shaft axis,
the bearing shaft axis of the bearing shaft of the damper bearing assembly is arranged orthogonal to the rotation axis, and
a shaft support portion supporting the bearing shaft, is provided between the damper bearings of the damper bearing assembly, which are adjacent to each other.
