Document Type and Number:
Japanese Patent JP6719876
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fitting, in which a seal portion of a fitting itself is opened at a stage to keep the coupling state in the fitting, even if a high pressure is applied, while being used, to the fitting or a hose by any cause, and in which a leakage is caused to lock to the outside via a fluid discharge passage, thereby to reduce the pressure and to enhance the safety.SOLUTION: In a fitting, a shrinking member is shrunken when the pressure of a fluid in a fluid passage abnormally rises thereby to retract the fitting body axially with respect to a fitting part body so that a seal part, of a seal member, with the fitting of a coupling partner is opened and a leak passage is formed to release the pressure fluid in the fluid passage to the outside.SELECTED DRAWING: Figure 1
