Claims

[Scope of utility model registration request]

A joint body is provided with a fluid flow path along the axial direction and has a joint portion on the outer periphery thereof that can be engaged with and detached from another flow pipe connection portion, and a joint body is provided with an annular projection in the flow path of the joint body. a check valve body having an end face facing the valve seat and slidably fitting into the flow passage; a guide groove provided along the axial direction on the circumferential surface of the check valve body; When fluid flowing from the direction of the valve seat collides with the check valve body, it deforms elastically and separates the end face of the check valve body from the valve seat.When fluid flowing from the opposite direction collides with the check valve body, this fluid pressure and its elastic force A joint structure with a check valve function, characterized by comprising a spring that brings the end face of the check valve body into contact with the valve seat and closes the guide groove.
