Abstract
In a balancer device () including a pair of balancer shafts (), the radial bearings (-) for the balancer shafts are formed solely in the balancer housing () and/or an integral extension () thereof. Because a pump cover () provided separately from the balancer housing does not include a radial bearing for either balancer shaft, the pump cover is not required to be attached to the balancer housing when machining the radial bearing bores in the balancer housing so that the manufacturing process is simplified, and the coaxiality of the bearing halves for each balancer shaft can be ensured without difficulty as opposed to the case where the pump cover is provided with a bearing bore which is required to be aligned with the corresponding bearing bore of the balancer housing.
