For example, as shown in Japanese Utility Model Publication No. 57-71677, a guide groove for a sliding door is provided on the inner surface of the front edge of the door, a shaft is provided directly protruding from the left and right sides of the lower side of the sliding door, and the shaft is inserted into the guide groove. It is designed to fit. Therefore, in conventional devices, since the sliding door is provided inside the doorway, the storage capacity inside the furniture body is reduced, and since the guide groove opens toward the inside of the furniture body, it is easy to get clogged with dirt, etc. There was a risk that it would not operate smoothly. The present invention is intended to improve such drawbacks; the sliding door can be provided on the outside of the front edge of the doorway of the furniture body, expanding the internal volume of the furniture body, and the guide groove etc. can be installed inside the furniture body. This relates to a sliding door opening/closing device for furniture that can be opened and closed smoothly for a long time without being exposed.
