A conveying apparatus for a rail vehicle seat. A drive device (2) and a support mechanism (4) are lifted to an appropriate height by lifting of a lifting device (3). A seat (1) is placed on the support mechanism (4), and the drive device (2) located on the lifting device (3) pushes the support mechanism (4) and the seat (1) to a mounting position in a rail vehicle, to complete conveying and locating of the seat. Compared to the prior art in which a person repeatedly gets in and out of a rail vehicle to move a seat to implement locating and mounting, the conveying apparatus implements automatic conveying and locating, and improves working efficiency and working convenience.
