摘要： PROBLEM TO BE SOLVED: To provide a connection structure capable of preventing nozzle clogging and fuel leak from an attachment surface even if a connection branch pipe is detached and then reattached. SOLUTION: A through hole connecting to a flow passage in a main pipe is included. An external circumference edge of the through hole is used as a pressure receiving seat surface opening in a conical shape. A coupling fitting formed as a separate body is externally fitted on an outer circumference wall part of a main pipe with surrounding the pressure receiving seat surface. A screw sleeve surrounding the pressure receiving seat surface part and having male screw on an outer circumference is inserted and is engaged with the coupling fitting and is fixed. A pressing seat surface formed on an connection part of a branch pipe is abutted on the pressure receiving seat surface part. A cylindrical sleeve is inserted between the branch pipe and the screw sleeve. A tip of the cylindrical sleeve is abutted on a pressing head part and a box nut which the branch pipe is penetrated through and is built in is fastened. Consequently, the cylindrical sleeve is pushed down by the box nut and the pressing head part is adhered on the pressure receiving seat surface. COPYRIGHT: (C)2007,JPO&INPIT
