a pinion drive shaft supported by and moveable over said ball bearing structure;

a pinion formed on said pinion drive shaft at the front end thereof, said pinion being moveable with said shaft, said pinion being disposed with respect to said front bracket such that a gap is formed in communication with said upper portion of said bearing structure; and

a water drain hole provided in the bearing support portion of said front bracket at said lower portion of said ball bearing structure and a water drain passage that communicates between said hole and said interior portion of said front bracket.
