The present invention provides a carrier elevating apparatus suitable for a low floor type conveying apparatus with carriers. A cam rail 36 extends along a horizontal running track, along which a carriage runs. The carriage includes a deck 1, on which an erectable cross-linking mechanism 3 is mounted. The cross-linking mechanism 3 supports and vertically moves a carrier 2A. The cross- linking mechanism 3,includes a link 14a and a link 14b. The link 14a is supported at its lower end pivotably by the deck 1 through a fixed horizontal pivot shaft 16. The links 14a and 14b are connected together at their middle points by a fulcrum shaft 15, which is parallel with the pivot shaft 16. The link 14a is fitted with a driven member 25 between the shafts 15 and 16. An elevator 27 is supported vertically movably by the deck 1. The elevator 27 includes a bearing member 32 fixed to its top and a cam follower 34 supported by its bottom. The driven member 25 is supported by the bearing member 32 horizontally movably relative to it. The cam follower 34 can follow the cam rail 36, lifting the elevator 27, so that the cross-linking mechanism 3 erects to elevate the carrier 2A.
