式つかみ具。 a first hydraulic cylinder arranged so as to be contractible in the direction of the load axis so that the cylinder body can be connected to the testing machine, and a grip body connected to the tip of the piston rod; and a bifurcated grip body. A pair of left and right second hydraulic cylinders that close grip teeth provided at the tip of the piston rod when hydraulic pressure acts on the head-side pressurizing chamber provided at the tip, and a pair of pressurizing chambers of the first hydraulic cylinder. a pair of pressurizing chambers of the second hydraulic cylinder, and a pipe line that communicates with the pair of pressurizing chambers of the second hydraulic cylinder, and the pressure generated in the first hydraulic cylinder due to the reaction force from the test piece is transferred to the second hydraulic cylinder. A hydraulic gripping tool, characterized in that each of the pressurizing chambers is communicated with each other through the pipe line so as to lead to the head side pressurizing chamber.
