Hydraulic cylinders (10) of a conveying apparatus (100) includes piston rods (21) that extend in parallel, pistons (22), and cylinder tubes (23) that have an internal pressure chamber partitioned into first and second pressure chambers (R1 and R2). A pair of the hydraulic cylinders (10) are arranged in parallel with an interval in a width direction of a conveyance path. The cylinder tube (23) slidingly moves to the first pressure chamber (R1) side by supplying a hydraulic pressure to the first pressure chamber (R1) and discharging a hydraulic pressure from the second pressure chamber (R2), and the cylinder tubes (23) slidingly move to the second pressure chamber (R2) side by supplying a hydraulic pressure to the second pressure chamber (R2) and discharging a hydraulic pressure from the first pressure chamber (R1). The workpiece (W) is supported by a pair of the cylinder tubes (23). |
