BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord stopper, and more particularly to a cord stopper.

[0002]

2. Description of the Related Art Conventionally, a cord stopper of this type is roughly classified into a hollow cylindrical case whose one end is closed and a movably housed in a hollow portion of the case, and an open end of the hollow portion of the case. A button that goes in and out of the case, and a spring that is housed in the hollow part of the case, is located between the closed end of the case and the button, and biases the button in a direction projecting from the open end of the case. It was made up of parts (eg.
No. 52412, Japanese Utility Model Laid-Open No. 2-28609, etc.).

In the case, a pair of insertion holes, through which the cords can be inserted, are formed so as to penetrate the outer periphery of the case so as to face each other with the hollow portion interposed therebetween. In the state where the button is pushed into the hollow part of the case against the biasing force of the spring, the button communicates with both insertion holes of the case in series, and the biasing force of the spring causes the button to open. In the state of protruding from the end portion, the communication hole is formed so as to be displaced from the both insertion holes of the case and restrain the string passed through the both insertion holes of the case.

After assembling the three parts of the case, the button and the spring, the button is pushed into the hollow part of the case against the biasing force of the spring, and the two insertion holes of the case and the communicating hole of the button are connected. They were made to communicate in series, and the string was passed from one insertion hole through the communication hole to the other insertion hole.
