[Effects of the Invention] The present invention has the above-described structure and operation. Since the diameter of the hole 5 is larger than the diameter of the support shaft 4, the support shaft 4 is set in the hole 5 when the opening / closing door 2 is opened. On the other hand, since the difference in diameter is free, the operation becomes lighter, and even if the dimensions of the end of the open / close door 2 and the door frame 3 are small, the open / close door 2 does not hit the door frame 3 and the open / close door 2 rotates while escaping. As a result, the opening / closing door 2 can be smoothly opened and closed without being stuck.

Further, since the support shaft 4 is positioned so as to be biased toward the locking piece 2a side on one side of the hole 5 when the opening / closing door 2 is opened, the opening / closing door 2 is closed and the locking piece of the opening / closing door 2 is closed. When the locking portion 3a of the door frame 3 is locked with the door frame 2a, the open / close door 2 is firmly attached without rattling, the dimensional accuracy of the open / close door 2 and the door frame 3 is improved, and the appearance is not damaged.

If the hole 5 is an Ω-shaped groove having a narrow opening 5a at the tip, it can be easily attached to and detached from the support shaft 4, and the opening / closing door 2 and the door frame 3 are made of resin. Since it is made of molded products, it can maintain a certain degree of springiness when attached and detached, and can maintain its performance even after repeated attachment and detachment for a long period of time.
