The track comprises an upwardly-extending shaped protuberance for movable securement thereto of complementary locking portions on the walker and a relatively flat outwardly-extending portion or platform for contact with wheels associated with the locking portions, so that the walker may be movably and removably secured to said track and moved along the track by the occupant of the vehicle by wheels riding on the flat portion of said track on the one side and by wheels riding on the floor on the other side of said walker. In a preferred embodiment, spring-biased track lock-on levers having complementary track lock-on hook portions are provided for convenient attachment to and detachment from the track.
