A carriage-type conveyance device using a carriage having a vertically movable object-supporting base that is controlled by a cam rail on the floor side, in which a turntable for changing the direction of the carriage has a low-floor structure. In the carriage-type conveyance device, the object-supporting base that is vertically movable between a lowered position and a lifted position is placed on a conveyance carriage (1), a cam follower roller vertically moving in association with the movement of the object-supporting body is provided at the bottom of the conveyance carriage (1), and a cam device (58) for pushing up the cam follower roller and a work section (3A) in which the object support base is supported at the lifted position are provided in a traveling route of the conveyance carriage (1). The conveyance device further has the turntable (7) placed in a traveling route on the downstream side of the work section (3A) and changing the direction of the conveyance carriage (1), and also has a means for holding at the lifted position the object-supporting body of the conveyance carriage (1) from at least the time immediately before the object-supporting body enters into the turntable (7) until it has exited from the rotated turntable (7).
