Provided is a holder device that uses a pressure medium suitable for grasping a long and thin object to be grasped, that does not require thinning of a device body, and that enables a material suitable for deformation of a sleeve to be used in a part where a pressure chamber is formed. A holder device capable of deforming in a radial direction in which an object (7) to be grasped will be clamped and fixed by the action of a pressure medium, the holder device comprising a device body (2), a sleeve (3) that is disposed at the tip of the device body (2) and that grasps the object (7) to be grasped, a pressure chamber (8) provided encircling the sleeve (3), and a support part (9) that is linked to the device body (2) and that forms the pressure chamber (8) together with the sleeve (3). |
