The joining structure of the present invention has been devised to solve such a problem, and its gist is (A) one side end surface of a pair of panels to be joined. A first opening having a predetermined width formed continuously or along a predetermined interval along the line, and (B) in the panel in which the first opening is formed, at the predetermined interval and wider than the first opening. A holding hole formed in the inner part in the direction, and (C) a second opening having the same width as the first opening formed at a position facing the first opening in the other of the panels to be joined or a joining member fixed thereto It has an opening and (D) a joint tool for connecting the pair of panels. The joint tool has (a) a shaft part fitted into the holding hole, and (b) the joint part at a specific angular position. Can pass through the first opening and rotate a certain angle from this Missing a stop portion which not pass through the opening in the rotating position, (c) said first aperture, has substantially the same width as the second opening, which first opening in said specific angular position,
A main body that cannot be inserted into the second opening and that can be inserted into the first opening and the second opening at the rotational position, and (d) connects the retaining portion and the main body with the first opening. A connecting portion that is relatively rotatable inside and fits into the first opening with substantially no gap at the rotation position; and (e) is fitted to the outside of the shaft portion, and when the shaft portion is fitted into the holding hole. A spring that urges the main body portion in a direction to protrude from the first opening by abutting on the peripheral edge portion of the holding hole, and the main body portion is configured such that the retaining portion has the first opening at the specific angular position. It is formed at a position where it is inserted / fitted into the second opening when it is located at a position where it abuts the back side peripheral edge portion of the first opening after passing through.

[0005]

In the joint structure of the present invention,
With the retaining portion of the joint tool positioned at the specific angle position, the retaining portion is passed through the first opening of the one panel, and the shaft portion is fitted into the holding hole.

When the joint member is rotated by a predetermined angle when the slip-out preventing portion passes through the first opening, the slip-out preventing portion cannot pass through the first opening in the pull-out direction, and the elastic force (biasing force) of the spring is exerted. By this, the peripheral edge of the back side of the first opening is brought into contact with a predetermined pressing force, whereby the joint tool is in a state of being prevented from coming off from the first opening.

At this rotational position, the main body of the joint tool is ready to be fitted into the first opening, whereupon the main body is pushed into the first opening against the biasing force of the spring. In this state, the joining surface of the other panel to be joined is aligned with the side end surface of the one panel.

At this time, the second opening formed in the other panel faces the first opening of the one panel. Then, the main body portion of the joint tool in the pushed state is projected by the biasing force of the spring and fits into the second opening.

That is, at this time, the retaining portion is brought into contact with the back side peripheral edge of the first opening under a predetermined pressing force by the biasing force of the spring, and the main body is fitted in the second opening of the other panel. Becomes Further, at this time, the connecting portion that connects the retaining portion and the main body portion is fitted into the first opening with almost no space. Here, the pair of panels are in a state of being joined to each other through the joint tool.

According to the present invention, the panels can be joined to each other from the inside of the room. Therefore, the workability in joining the panels is good, and the panels can be joined efficiently in a short time.
