CONVEYING DEVICE

PURPOSE:To increase efficiency in assembling work by conveying a conveyance object having a caster without a pallet, and installing an ascending and descending machine. CONSTITUTION:Rails 1 to guide both side surfaces of a caster of a conveyance material are laid down, on an assembling line, and a hook 2 to push the conveyance object is arranged, and a driving system is arranged to move this hook 2 longitudinally along the rails 1. A lifter 3 is installed in an assembling work place, and a plate where the rails 1 are laid down on an upper surface of this lifter 3 is arranged at an interval. A structure is formed in such a way that a stopper to fix the conveyance object is attached to the lifter 3, and the caster on the rails 1 is made fixable or releasable by ascent and descent of the lifter 3, and ascends together with this plate when it is further raised. Thereby, since manufacturing cost is reduced and conveyance weight is lightened, a driving motor is downsized, and the running cost is reduced.
