Abstract
A balance shaft housing (an upperhousing U and a lower housing L) disposed in an oil pan ( ) for accommodating balance shafts ( L, R) provided with counterweights ( ) for canceling out the vibromotive force caused by pistons, characterized in that an intake passage (an intake pipe ) of a pump ( ) for taking in lubricating oil within the oil pan is formed integrally with the housing, and that an oil strainer attaching portion ( ) is formed integrally with a bearing wall (a first bearing wall ) for supporting the balance shafts. According to this construction, since the thickness of the oil strainer attaching portion increases the rigidity of the bearing wall supporting the balance shafts, the increase in rigidity of the housing can be attained without increasing the thickness of the housing.
