A hemming device (10) configured in such a manner that pressing rollers (2b, 2c) which are mounted to a robot (1) are pressed against a workpiece (W), which is placed on an anvil (8), to hem the workpiece (W). The hemming device (10) is provided with: a welding section (60) having a movable electrode (64) for welding the workpiece (W); a support member (3) for rotatably supporting the pressing rollers (2b, 2c) and supporting the movable electrode (64); and a drive device (4) mounted to the robot (1) and rotating the support member (3). A portion of the support member (3), the portion being separated from the portions at which the support member (3) supports the pressing rollers (2b, 2c) and the movable electrode (64), is affixed to the rotation shaft of the drive device (4). The torque generated by the drive device (4) rotates the support member (3) to press the pressing rollers (2b, 2c) and the movable electrode (64) against the workpiece (W).
