A chair in the saloon (5)
I believe the answer is:
sedan
This clue is a double definition.
'a chair' is the first definition.
(Sedan chair is a type of chair)
'the saloon' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for sedan that I've seen before include "Battle in 1940" , "Where Prussians defeated French" , "Chair used as transport" , "In cars, an alternative name for 'saloon'" , "Saloon-car" .)
