Claims

[Scope of utility model registration request]

A universal joint used in a flexible supply circuit extending from the end of a fixedly installed combustion gas supply pipe to a gas combustion appliance includes a tubular female member 1 and a male member 2, both of which have a fluid passage 3 penetrated through the center. is provided with a connecting end 4 at each end thereof which can be connected to all components forming the flexible supply circuit, including the end of the fixed gas supply pipe and the hose end of the gas combustion appliance; In 1,
A large diameter O that opens at the end that does not have the connection end 4
Ring engaging portion 51, an inner circumferential tapered portion 52 having a smaller diameter in the direction of the end where the connecting end 4 is provided, and an annular groove whose groove bottom position is a diameter larger than the small diameter of the inner circumferential tapered portion 52. 53, the small-diameter O-ring engaging portion 54 is recessed in the above-mentioned order so that the fitting recess 5 has its tip communicated with the fluid passage 3, while the male member 2 is recessed in the above-mentioned order. A fitting connection part 6 having a shape that allows the end opposite to the forming position of 4 to be fitted and inserted into the fitting recess 5 is arranged in order from the larger diameter to an engaging part 61, an annular groove for a retaining ring 62, and an engaging part 63. are provided, and the engaging parts 61, 63
At the same time, a large and small O-ring 7 that matches the engagement diameter is engaged, and a C-shaped retaining ring 8 is press-fitted into the annular groove 62 for the retaining ring, and the fitting connection portion 6 is inserted. The C-shaped retaining ring 8 is press-fitted into the fitting recess 5, and the outer periphery of the C-shaped retaining ring 8 is immersed in the annular groove 53, thereby connecting the female member 1 and the male member 2 into one body using the C-shaped retaining ring 8 as a connecting medium. A universal joint for use in a combustion gas flexible tube supply circuit, characterized by comprising:
