装着してなる流体継手。 Consisting of a female main cylinder 1 and a sub-cylinder 2 having a valve body 3 for opening and closing a flow passage inside, a small diameter portion 1a on the coupling side of the female main cylinder 1 is provided with a diameter 1a that is perpendicular to the axis and inclined inward from the circumferential surface toward the coupling side. A slit 5 is provided, a lock pin 6 is fitted into the slit 5, and the lock pin 6 is engaged with and disengaged from the annular groove 14 of the male main cylinder 11 having a tapered portion and an annular groove to connect the female and male joints A and B. In a fluid coupling for separation, an inner sleeve 7b having an outer diameter approximately equal to the length of the lock pin 6 is fitted into the small diameter portion 1a on the coupling side of the female main cylinder 1 with a spring biased toward the coupling side, and the inner sleeve 7b is inserted into the small diameter portion 1a on the coupling side of the female main cylinder 1. is pressed into contact with the end of the lock pin 6, and on the outer periphery of the inner sleeve 7b is a cylindrical portion of the outer sleeve 7a consisting of a cylindrical portion 7a ₁ whose inner diameter is slightly larger than the length of the lock pin 6 and an inward flange portion 7a ₂ on the connecting end side. 7a A fluid coupling formed by installing ₁ in an integral relationship.
