Description of the Related Art Conventionally, in assembled furniture or the like in which a shelf member is supported in the middle of extension of a column, for example, a shelf member is divided in a longitudinal direction into a mounting hole formed by forming a tubular portion. Both ends of the two columns are respectively inserted from both sides, both ends are fitted inside the mounting hole, and a clip inserted into the tubular part from the outside is passed through both ends. Thus, it is known that the two columns can be joined to the shelf member by a simple work, and can be disassembled by removing the clip (Japanese Patent Publication No. 58-5808).
(See Japanese Patent No. 7).

[0003]

However, in such a conventional structure, it is good when disassembly after assembly is possible, but when disassembly is not required, two wires are provided on both sides of the mounting hole. Since it is necessary to insert clips further after inserting the respective ends of the columns, the workability in connecting the shelf member and the columns is poor. Further, since the two columns are connected to each other via a clip which is a separate member, it is difficult to eliminate rattling of the columns connected to the shelf member.

The present invention has been made in view of such conventional problems, and has a good workability in connecting a shelf member and a support, and a shelf member capable of connecting both without rattling. The present invention relates to a connection structure with a pillar.

In order to solve the above-mentioned problems, according to the present invention, an end portion of a column is inserted into a mounting hole opened in a shelf member from one direction and another member is inserted from another direction. In a structure in which the shelf member and the column are coupled by inserting the end portions and engaging the both end portions inserted in the mounting hole with each other, the mounting portions are attached to the both end portions. fitting portion fitted into the hole are respectively formed, one
A second fitting portion that fits inside the fitting portion on the other side is provided at the tip of the fitting portion on the other side, and a first fitting portion that closely contacts the inner peripheral wall of the mounting hole of the fitting portion on the other side is provided. the wall is provided with a engaging claw projecting towards the inside, that the second fitting portion Yusuke
An engaging portion with which the engaging claw is engaged is provided on the second wall. In addition, the other member is configured to be another pillar connected to the shelf member.

[0006]

In the above structure, when the support pillar and the other member are inserted from both sides of the mounting hole, the support pillar and the other member are formed on the first wall and the engaging portion formed on the second wall. By engaging the engaging claws, it is possible to prevent the engaging claws from coming off the mounting holes.
At this time, since the first wall of the engaging claw comes into close contact with the inner wall of the mounting hole, it does not come off from the engaging portion. Therefore, the slipping off can be reliably prevented. On the other hand, as for the strut and the other member, the respective fitting portions are fitted inside the mounting holes, and at the same time, the second fitting portion formed on the fitting portion on one side is fitted inside the fitting portion on the other side. By fitting, the strut can be prevented from rattling in a direction intersecting with the insertion direction (removal direction) into the mounting hole.

Further, when the other member is another column, the two columns can be simultaneously joined to the shelf member.
