To provide a carrier device propelled by a friction drive means having carrier carriages disposed in a traveling route side in all the traveling route.

This carriage type carrier device is so constituted that a main traveling line 1 and a sub-traveling line 5 are provided in the traveling route of the carriages 2, and the carriage 2 is provided with main drive friction surfaces 20a formed of sides parallel to the traveling direction in left/right both sides of a loading space 7 or its adjacency and sub-drive friction surfaces 21a formed of sides of a rod body 10 attached in parallel to the traveling direction in the central part in the left/right width direction in the lower side of the loading space 7. The main traveling line 1 comprises a straight traveling route and has a main propulsion driving means 3 with a friction drive wheel 23 pressure contacting with a main drive friction surface 20a of the carriage 2. The sub-traveling line 5 has sub-propulsion drive means 6A and 6B with friction drive wheels 25 pressure-contacting with sub-drive friction surfaces 21a of the carriages 2 disposed at appropriate intervals in the carriage traveling direction.
