(54) Engine balancer


(57) To provide an engine balancer that facilitates discharge of an oil. A distance between a balance shaft (25) and an inner peripheral surface (23c) is gradually reduced to an opening (41a) of an oil discharging path (41) of an oil discharging path (41) in a rotational direction (counterclockwise direction in the drawings). Since the distance between the balance shaft (25) and the inner peripheral surface (23c) of a weight chamber (23) is reduced, a force is applied in such a direction as to compress the flowing oil. The applied pressure pushes out the oil flowing along the balance shaft (25) into the oil discharging path (41).
