  • Case structure of driving power transfer apparatus
    Patent number: 5941136
    Abstract: A transfer case of a driving power transfer apparatus is connected to a transverse engine through a transmission in an automotive vehicle. The transfer case has a case body which includes a cylindrical portion, an opening portion connected to an end of the cylindrical portion and a bolt connecting portion formed around the opening portion. The opening portion is connected to the cylindrical portion in offset connection such that a part of the bolt connecting portion is overlapped with the cylindrical portion as viewed from the axis of the opening portion. An adapter is connected to the bolt connecting portion by means of bolts and has a cylindrical engaged portion which is sealingly engaged with the first opening portion of the case body. Therefore, a clearance between the transfer case and the engine is sufficiently ensured to improve the degree of freedom in the layout of the engine.
