Claims

[Scope of utility model registration request]

It has a pair of side plates that maintain an interval at which the tip of the arm of a civil engineering machine such as a power shovel is inserted, and the side plates are provided with a claw support part on the tip side and a pin fixing part on the other end side, and the pin fixing part is provided with the nail support part on the other end side. In a bracket for a gripping device in which a gripping claw consisting of an upper claw and a lower claw that opens and closes each other and is pinned to the tip of the arm is supported by the claw support portion, a rotation link that constitutes a link mechanism for a bucket attached to the arm; and a bracket for a gripping device, characterized in that a rotation link mounting portion, to which the rotation link is rotatably attached, is provided to protrude upward from the upper part of the side plate in correspondence with the operation link.
