PURPOSE:To enable satisfactory washing with a simple washing operation by providing a female side spring and male side spring outside an inside fluid path. CONSTITUTION:Both or one of female and male joints 19, 20 are shifted such that the tip sides of the male and female joints 19, 20 are opposed and moved close to each other on the same axis. At first, the tip surface of a male body abuts against the tip surface of a valve seat part 22 of the female joint 19 through an annular seal 55 to divide the inside of the annular seal 55 from the outside. Then, nearly at the same time, the female and male side valves 23, 41 abut against each other on the respective tip end surface. Further, while the moved male body moves back the valve seat part 22, the female side valve 23 substantially moves back the male side valve 41. That is, the female side valve 23 stops the male side valve 41 at a fixed position in the advance of the male body, so that a female side valve hole 30 and male side valve hole 45 are opened. Under such a condition, fluid flow therethrough. Since springs 24, 42 are absent in an inside path under the connecting condition of the joint for fluid, the fluid does not enter a gap between the springs 24, 42 and between the spring receiving ports. |
