  • Patent number: 9682412
    Abstract: Hemming finishing pliers press and thereby bring a folded portion of a panel into close contact with an inner surface side of the panel facing the folded portion, by a clamping action of first and second holding arms. A pressure receiving plate for supporting an outer surface of the panel is provided in a tip end portion of the first holding arm. A pressing claw for pressing the folded portion against the panel supported by the plate is provided in a tip end portion of the second holding arm. A pressure receiving surface of the plate facing the outer surface of the panel is set wider than a pressing surface of the claw facing the folded portion. A supporting wall for supporting a flexed part of the folded portion is formed in the plate. Accordingly, the pliers enable efficient hemming finishing without requiring a skill.
