DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension guide device for a door used for opening and closing an opening of various storage furniture and a built-in storage space.

[0002]

2. Description of the Related Art In a suspension guide device in which an upper portion of a door is suspended by a guide rail so as to be able to travel in an opening and closing direction, a guide rail having a substantially C-shaped vertical section has a door-side portion. In a state in which the suspending roller of the suspending traveling roller unit is detachably engaged, the suspending roller is easily detached from the guide rail when a lifting force is applied to the door, so that such a situation is prevented. Means for preventing the roller from coming off is required.

As a means for preventing a roller from coming off in this type of a door suspension guide device, for example, a suspension roller is engaged with a rail portion of a guide rail, and then a screw is screwed in so that the tip of the roller is placed under the rail portion. Although it was conceived that the roller could be inserted into the side, both of the function setting and the function release for preventing the roller from coming off had the disadvantage that the operation was troublesome and time-consuming.
