The guide rail 7 is substantially U-shaped in a plan view, and is composed of three straight portions and right and left corner portions having a predetermined radius of curvature. Further, the guide rail 7 has a groove portion 8 having a rectangular cross section and horizontal piece portions 9 and 9 protruding laterally.

Reference numeral 10 is a slide piece with a collar made of hard plastic such as DURACON, which has a circular collar portion 11 that is in sliding contact with the guide rail 7, and a cylindrical protrusion portion 12 that is inserted and fixed to the vertical column 2. It has a cylindrical fitting portion 13 which is slidably fitted in the groove portion 8 of the guide rail 7.

Then, as shown in FIGS. 3 and 4, the upper and lower edges of the door member 1 are slidably fitted in the groove portions 8, 8 of the guide rails 7, 7, and the flanged slide pieces 10 are vertically slid. The pillars 2 are attached to the upper end and the lower end of the pillar 2, and the collar portion 11 of the lower slide piece 10 with the collar is slidably contacted with the horizontal piece portions 9, 9 of the lower guide rail 7 to form the door member 1 and the vertical member. It is configured to support the weight of the pillars 2 ...

As a result, the door member 1 floats in the air with respect to the guide rails 7 and 7, and the predetermined gaps A and B are formed between the upper and lower edges of the door member 1 and the bottom surfaces of the grooves 8 and 8. Occurs.

Further, at the horizontal piece portions 9, 9 of the lower guide rail 7, the collar portion 11 of the lower slide piece 10 with a collar is slid so that the door member 1 and the vertical pillars 2 ... It is possible to move along 7 and 7, and at the time of movement, friction resistance is small and slip is good, so it can move lightly and smoothly.

As shown in FIGS. 4 and 5, the door member 1 having the step portions 19 and 19 includes a base material 14 made of plywood or particulate board, a surface material 15 made of expandable polyvinyl chloride, and a base material.
