The bottom of the shoe is bent and slightly protrudes. Inside the groove on the sill, a slit corresponding to the protrusion is formed. According to the present invention, the structures of the shoe and sill prevent separation of the door, and reinforces the entire strength of the door, reducing unnecessary expenses for preventing separation of the door. Furthermore, when abnormal impact or power is applied to the hoistway door and the hoistway door is accidentally opened, this invention prevents a user from falling into the shaft. |
