The cycloid reducer of the present invention comprises an output flange, a rotating shaft, a bearing and a preload adjustment device. The output flange has an adjusting screw hole. The rotating shaft has an output end penetratingly disposed in the output flange. The bearing has an inner ring provided to the output end of the rotating shaft and an outer ring provided to the output flange. The preload adjustment device has a preloading plate and an adjustment screw. The preloading plate is adjacent to the output end of the rotating shaft and abutted against the outer ring of the bearing. The adjustment screw is screwed into the adjustment screw hole of the output flange and has one end abutted against the preloading plate. In this way, when the adjustment screw is rotated, the preloading plate can be pushed by the adjustment screw and further being abutted against the outer ring of the bearing, so that the preloading plate exerts a pre-pressure to the bearing.
