Abstract: Provided is a roller hemming apparatus capable of preventing positional misalignment of a lower plate workpiece during a bending process. A roller hemming apparatus of the present disclosure includes a die configured to hold a first workpiece which is a plate material, and a roller configured to bend an edge of the first workpiece onto an edge of a second workpiece, which is a plate material placed on the first workpiece held in the die, to overlap each other, the die including a suction mechanism that opens toward a workpiece contact surface against which a hem flange on a peripheral edge of the first workpiece abuts, and that suctions the first workpiece. Thus, positional misalignment of the first workpiece is prevented during a hemming process.

Abstract: A vehicle body assembling apparatus includes a lower jig, an upper jig movable by an arm of a robot, and a joining device. The joining device performs joining operations for lower component parts (e.g., a temporary assembly of a rear floor frame) transported by the upper jig and positioned by the lower jig, upper component parts (e.g., a temporary assembly of a rear floor panel) held by the upper jig, and a temporary assembly of a vertical assembly (e.g., rear floor component) formed by overlapping the upper assembly with the lower assembly, above the lower jig at different timings.
