パ。 In a gripper for handling nuclear fuel, which grips and separates fuel by opening and closing a swinging claw equipped on the main body casing of the gripper by operating an actuator, a groove surface is provided above and opposite to the rotating guide pin of the claw. Equipped with a downwardly open U-groove pin guide member and a biasing spring that constantly urges the claw upward so as to draw the guide pin of the claw into the groove of the pin guide member in a no-load state, For handling nuclear fuel, characterized in that a shoulder for supporting the claw is formed at the lower part of the casing side opposite to the claw so that the fuel load applied to the claw when hanging the fuel is transmitted directly from the claw to the casing and supported. Grizpa.
