To provide a mechanical type transportation device allowing the use of two types of floor type and overhead type, facilitating maintenance, providing excellent work environment, and preventing reliability of running from being affected by installation precision and having a simple structure.

This mechanical type transportation device is provided with a rail 15, a rotary shaft 17 provided in parallel along the rail 15, a carrier 26 having a pair of front and rear side running carriers 23, 24 provided along the rail 15 and a pedestal 25 for load, and driven rollers 54, 55 provided in the pair of front and rear side running carriers 23, 24, respectively, and pressed and abutted on an outer peripheral face 53 of the rotary shaft 17. The driven rollers 54, 55 are turned in synchronization. An angle α formed by a tangential line s of the driven rollers 54, 55 and a ridge line n of the rotary shaft is controlled between a stop angle α0 in 90 degree condition and a conveyance angle α1smaller than 90 degrees at a point 0 where the driven rollers 54, 55 come into contact with the rotary shaft 17 to move and stop the carrier 26.
