CONNECTING STRUCTURE OF PIPE, CONNECTING STRUCTURE OF FLEXIBLE PIPE AND GAS APPLIANCE

Japanese Patent JP3821955

B2

PROBLEM TO BE SOLVED: To provide a connecting structure of a pipe having no possibility of generating gas leakage.
SOLUTION: This connecting structure of a pipe is provided with couplings 10, 16 in which a center hole 23 is formed at the inside and a coupling main body 32 which is fixed to the tip part of a pipe 12 and is connected attachably/ detachably to/from the couplings 10, 16. A cylindrical narrowing diameter part 46 which is relatively reduced via a projecting step part 50 and is inserted within the center hole 23 of the couplings 10, 16 is formed at the tip of this coupling main body 32. By mounting an O-ring 42 on the outer periphery at the root of this narrowing diameter part 46 and notching cross section at a right angle throughout the entire periphery of the inner periphery of the center hole 23 on the inner peripheral side of the tips of the couplings 10, 16, a notched step part 40 for storing the O-ring 42 is formed.
