Dust cover structure for a power transmission member

A vehicle comprising:

• an engine having an output shaft;
• an axle for supporting wheels of said vehicle;
• and
• a power transmission member for transmitting output power of said engine to said axle, said power transmission member comprising:
• a shaft having first and second ends;
• a large diameter spline section formed on said first end of said shaft;
• a tubular joint section having splines for engaging with said splines of said large diameter spline section;
• a large diameter portion formed on said shaft adjacent to said large diameter spline section;
• and
• a generally tubular dust cover extending between said large diameter portion of said shaft and said tubular joint section, said dust cover including a first end having generally the same diameter as said large diameter spline section and a second end having generally the same diameter as said tubular joint section.

A power transmission for transmitting output power of an engine to an axle of a vehicle comprising:

• a shaft having first and second ends;
• a first large diameter spline section formed on said first end of said shaft and a second large diameter spline section formed on said second end of said shaft;
• first and second tubular joint sections having splines for engaging with said large diameter spline sections on said first and second ends, respectively, said first tubular joint section for transferring motion from the engine to said first end of said shaft and said second tubular joint section for transferring motion from said shaft to the axle of the vehicle;
• first and second large diameter portions formed on said shaft adjacent to said large diameter spline sections on said first and second ends of said shaft, respectively;
• and
• first and second generally tubular dust covers extending between said first and second large diameter portions of said shaft and said first and second tubular joint sections on said first and second ends, respectively, each of said first and second dust covers including a first end having generally the same diameter as said large diameter spline sections on said first and second ends, respectively and a second end having generally the same diameter as said tubular joint sections on said first and second ends, respectively.
