摘要： PROBLEM TO BE SOLVED: To surely shut off in emergency, and make an emergency shutoff mechanism work regardless of a bent of a horizontal branch pipe part with flexibility due to an application of an external force. SOLUTION: A branch saddle 31 comprises a saddle part 33 fused on a surface of a synthetic resin pipe 32, and a perforating pipe part 35 erected on the saddle part. A tapping cutter 36 is provided on an inner surface of the perforating pipe part 35 of the saddle to perforate on a surface of the synthetic resin pipe. A shutoff value unit 37 is provided in the tapping cutter to shut off a passage in the valve when a pressure difference between the upstream and the downstream becomes more than a prescribed pressure when the flow rate in the downstream increases. This branch saddle with the shutoff valve maintains the tapping cutter on the inner surface of the perforating pipe part of the saddle. The tapping cutter 36 has a passage where liquid communicates in a gap to the inner diameter of the perforating pipe part 35 of the saddle. The liquid in the synthetic resin pipe 32 flows from the perforating pipe part 35 of the saddle to a branch pipe part 34 provided on the perforating pipe part through a valve unit attached inside the tapping cutter 36.
