We are developing a sliding door device that rolls along a rail. Such door body end faces c, d
The structure is such that when the door bodies are housed in the door body housing part (not shown), the end faces c and d rub against each other and easily overlap each other when the door bodies are housed in the door body housing part. This is for the purpose of Note that 27 is a connecting link for interlocking the door bodies, and 42 is a sealing material.

However, in this sliding door device, when the guide roller 20 provided at the bottom of the door body 5A is rolled along the lower rail 3, as shown in FIG. Since the body 5A protrudes to the outside of the room, the upper and lower frames must be designed and structured to take this protrusion into consideration, which poses a problem in that the upper and lower frames become larger. In addition, as shown in FIG. 9, since the end faces c and d of the abutting portions of the door bodies 5A and 5B in the door frame curved portion 1x are in different directions, the sealing effect of the sealing material 42 is incomplete, and the air There was a problem with poor watertightness.

(Problems to be Solved by the Invention) In view of the above-mentioned problems, the present invention is designed to prevent the door body from protruding toward the outside when the door body moves through the door frame bending portion, and to prevent the door frame from protruding from the edge of the door frame. It is an object of the present invention to provide a sliding door device with improved air/water tightness at the abutting portions.

(Means for Solving the Problems) The present invention provides an engaging portion that removably engages with an adjacent door body at the end of the door body in the width direction, and each engaging portion is arranged horizontally. The cross-sectional shape forms an arcuate hook shape with a rounded tip, and when the engaging portions of adjacent door bodies are engaged with each other, the rounded tip arc surface forms an arcuate hook shape with a rounded tip. A U-shaped guide rail is provided at the lower part or upper part of the door frame that supports the door body, and is configured to fit into the arcuate inner surface of the engaging part of the door body and hold the door frame. The door is characterized in that a guide is provided at the lower part or the upper part of the joint part to be movably fitted into the guide rail and to hold the engaging parts of adjacent door bodies in the engaged state. When the door body is opened and closed, the ends of the door body are opened and closed with their ends interlocking with each other, which prevents the ends of the door body from protruding at the curved part of the door frame. Since the ends of the door body remain engaged, air and water tightness is maintained.
