特徴とする揺動可能なシールドジヤツキ。 In shield excavators, tunnel excavators, inclined shaft tunnel excavators, etc. that press the shield jack against a reaction force member to obtain digging reaction force and dig, the base of the shield jack is supported on the machine side with a spherical seat or hinge. The entire shield jack is arranged at an angle with respect to the machine axis line from the initial installation stage, and the spreader provided at the tip of the rod of the shield jack is brought into contact with the reaction member, and the shield jack is A swingable shield jack, characterized in that a swinging means is provided to cause the shield jack to follow changes in the angle of inclination as the jack expands.
