Invention endlessly contributive to transportation (5)

I believe the answer is:

wheel

I'm a little stuck... Click here to teach me more about this clue!

'invention' is the definition.
(I have seen 'Revolutionary invention' mean 'wheel' so perhaps 'invention' could also mean 'wheel')

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for wheel that I've seen before include "- - of Fortune" , "One needless to reinvent" , "Ship's steering device" , "revolutionary device" , "Circular steering device" .)

I've seen this clue in the Evening Standard.
