PROBLEM TO BE SOLVED: To reduce the number of rotation transfer components in a conveying device rotationally driving a plurality of conveyor rollers arranged in an arch shape collectively by one drive shaft.SOLUTION: A plurality of conveyor rollers 110A to 110E is arranged in an arch shape along a conveying direction of a workpiece W. A drive shaft 120 has bending elasticity and is warped into the arch shape within a range of elastic deformation, so as to follow an arched arrangement of the plurality of conveyor rollers 110A to 110E. A plurality of first gears 130A to 130E are fixed to the drive shaft 120 axially in a line corresponding to the respective conveyor rollers 110A to 110E. A plurality of second gears 140A to 140E is fixed to rotary shafts of the respective conveyor rollers 110A to 110E and transmits rotation of the drive shaft 120 to the respective conveyor rollers together with the first gears. A plurality of bearings 150A to 150G is arranged in the arch shape, so as to follow the drive shaft 120 warped into the arch shape and pivotally supports the drive shaft 120. A motor 160 rotationally drives the drive shaft 120. |
