範囲第１項に記載のクランプ装置。[Claims for Utility Model Registration] (1) A main body, a first link provided on the main body so as to be rotatable about a first rotation axis, and a second link parallel to the first rotation axis. a clamp arm rotatably provided on the main body around a rotation axis; and a clamp arm rotatably connected to the first link and the clamp arm by a first connecting pin and a second connecting pin, respectively. and two links, and by applying rotational force to the first link, the clamp is in a state where the second connecting pin is located on a straight line connecting the first rotating shaft and the first connecting pin. In a clamping device in which an arm presses a predetermined member to be clamped, the force in the linear direction is applied to the first link in a portion between the first rotation axis of the first link and the first connecting pin. 1. A clamping device comprising: a curved portion that elastically deforms when the first rotating shaft and the first connecting pin are applied to allow the first rotation shaft and the first connecting pin to approach and separate from each other. (2) The curved portion is such that a portion of the first link between the first rotation axis and the first connection pin is curved into an arch shape within the rotation plane of the first link. The second connecting pin is located between the first rotating shaft and the first connecting pin in a clamped state, and the rotating force rotates the first link in the clamping direction. When moving, it acts in a direction to close the bow shape,
The clamping device according to claim 1, wherein the clamping device is actuated in the direction of opening the arcuate shape when the device is rotated in the unclamping direction.
