Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in Figure 1, the sliding door (D) provided with a timing belt departure preventing member according to the present invention is a timing belt 20 that receives the power from the drive unit 100 to rotate in accordance with a predetermined track Equipped,

The timing belt 20 is connected and fixed to the upper portion of the door panel Da,

The door panel Da is provided with a roller in order to reduce frictional resistance and noise when the rail R moves along the frame P provided thereon.

The door panel Da is opened or closed in both directions according to a space to be installed, or is installed in one direction in a place such as a connecting passage entrance of a train having a narrow space, or three or more door panels are interlocked to open and close.

The driving unit 100 and the motor (M) fixedly coupled to the frame (P),

It is arranged on the rotation shaft (Ma) and the frame (P) of the motor (M), respectively, and are arranged facing each other at intervals to ensure the opening and closing movement displacement of the door panel (Da),

The timing belt 20 is made of two pulleys (10a, 10b) hanging while maintaining a constant tension state,

In the drawing, the motor M and the rotation shaft Ma are deformed in a direction of transmitting power by using a general bevel gear or the like.

As the rotation shaft Ma rotates forward and backward by the power transmitted from the motor M, the pulley 10a coupled to the rotation shaft Ma rotates and the timing belt 20 is engaged with the pulley 10a. Is rotated and the door panel Da, which is connected and fixed to the timing belt 20, is to open and close.

In the sliding door according to the present invention, the separation preventing member 30, which is a core, is applied to any one or both of the pulleys 10a and 10b of the driving unit 100 when the door panel Da is forcibly opened and closed. Is provided so that the timing belt does not pass over the teeth 11 of the pulleys (10a) and (10b), and eventually block the movement of the door panel.
