The bottom wall of the annular groove is formed by being fluid-tightly fitted to the circumferential surface or the outer circumferential surface, and is formed by closing the opening of the annular groove with the main body. In a hydraulic holder in which a thin wall portion constituting the body bulges out and holds an object in close contact with an object previously fitted to the thin wall portion, an end surface of the main body and an end surface of the flange facing the front end surface. A notch is provided on either one of the surfaces to form an O-ring groove that opens in the opposite direction to the direction in which the flange extends in cooperation with the other surface, and an O-ring is disposed in the formed O-ring groove. At the same time,
A hydraulic holder characterized in that the annular groove extends at least to a position facing the O-ring groove.
