ABSTRACT:
A transmission housing arrangement accommodates a plurality of meshing gears and comprises a main housing accommodating a part of meshing gears, an extension housing connected to the main housing and accommodating other meshing gear, and an intermediate plate partitioning the extension housing from the main housing and having a through hole at a lower portion of the intermediate plate for communicating the extension housing to the main housing, wherein the extension housing comprises a bottom wall defining a room under the meshing gear in the extension housing and a lubricating oil passage from the through hole to the room, the lubricating oil passage so curved that a flow of the lubricating oil into said extension housing is limited, whereby the meshing gear in the extension housing is prevented from sweeping up to much lubricating oil.
