Claims

[Scope of utility model registration request]

A disk-shaped ferrule with a fitting hole in the center through which a synthetic resin tube is fitted and inserted, and a short cylindrical member having a through hole coaxial with the column axis and having approximately the same diameter as the inner diameter of the tube. A male threaded portion is formed on the outer peripheral surface near the center from both ends, and the male threaded portion on one end is screwed into a female threaded portion formed on the inner wall of a round hole-shaped recess provided in the synthetic resin electromagnetic valve body. a joint member that is formed to fit together and communicates the tube through the through hole with a through hole formed in the electromagnetic valve body so as to open at the center of the bottom of the recess;
It has an engagement recess with which the other end of the joint member engages, and further has a storage space on the back side of the engagement recess for storing the ferrule with one side facing the open side of the engagement recess. A tube insertion hole is provided approximately at the center of the bottom wall of this storage space, and the ferrule is screwed into the inner wall of the engagement recess to the male threaded portion on the other end of the joint member so that the ferrule faces the end surface of the joint member. A tube fitting structure comprising: a nut member formed with a female threaded portion; and a core rod capable of being engaged and inserted into a through hole of a joint member and into the tube.
