BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom cabinet having a sliding door, more specifically, a protruding portion is formed on a front surface of a lower panel of a cabinet, upper and lower guide grooves are formed in the protruding portion, The upper and lower plates and the side plates are formed in the same shape so that the manufacturing time and cost can be drastically reduced. The upper and lower rollers are fastened to the upper and lower parts of the mirror body, The upper and lower reinforcing bars are connected to each other by a hinge. The elastic springs are connected to each other so that the rollers of the upper roller are elastically pivotally attached to the guide grooves of the upper plate. The lower roller Is seated in the guide groove of the lower plate in a state where it is attached to the lower reinforcing bar, thereby preventing the door from shaking when the sliding door is opened and closed And more particularly to a bathroom cabinet having a sliding door that can open and close the door more smoothly.

In the case of a cabinet for a bathroom, which is generally fixed to a wall of a bathroom and accommodates a bathroom article such as a towel, it is formed of both side plates and a rear plate for connecting the upper and lower plates to the upper and lower plates, and two sliding doors are slidably moved to open and close the cabinet. And a mirror is attached to the front of the sliding door or the sliding door itself is used as a mirror.

A guide rail is provided at the lower portion of the upper plate and the lower plate of the upper plate so that the sliding door can be slidably moved, and a roller device corresponding to the guide rail is coupled to upper and lower portions of the sliding door.

For example, in the case of a bathroom cabinet having a curved double door, a first guide rail and a second guide rail are formed on the front surface and the upper and lower ends of the frame of the bathroom cabinet, respectively, A first door having a rounded corner surface slidable in the left and right directions is connected to the first guide rail at a front side of the frame and connected to the second guide rail in front of the first sliding door, And a second door having a rounded corner surface slidable in the left and right directions is formed.

Therefore, it is possible to maximize the external aesthetic feeling by rounding the corner of the door with a curved surface, and it is possible to improve the efficiency of the space by minimizing the space occupancy by forming the sliding door so as to slide left and right there was.

However, in the case of the conventional bathroom cabinet, the first guide rail and the second guide rail must be provided separately on the front of the frame, and when the door is opened by pushing the door to the left and right, the guide rail is exposed to the front.

Further, there is a fear that the guide rails are deformed due to the structure in which the weight of the door is supported by the guide rails, and there is a problem that when the door is opened and closed, the door rails and noise are generated.
