Guide pins 4 are provided on the floor surface 11 at appropriate intervals so as to be projectable and retractable by magnetic force. And the hanging door body 3
A concave portion 23 is formed between the front and back face plates 25 at the lower end of the concave portion 23, and magnet blocks 21 and 21 holding a magnet M ₁ are loaded at both ends in the longitudinal direction of the concave portion 23. A plate material holding block 22 in which a magnetic material plate M ₂ is inserted and held is loaded, and the inside of the magnet block 21 and the plate material holding block 22 is formed as a running groove 5. A guide pin 4 is embedded in the floor surface 11 so as to be vertically movable.

However, when the hanging door main body 3 travels in the closing direction, the guide pin 4 sinking under the floor is magnetically attracted by the attraction magnet 7 of the magnet M ₁ and pulled up.
Is rushed into the running groove 5 on the lower end surface of the hanging door main body 3, and the running state can be maintained by the magnetic attachment to the magnetic material plate M ₂ to guide the running. Guide pin 4
Is inserted into a cylindrical case 12 embedded under the floor so that it can be moved up and down, and a magnet 6 is attached to the head of the guide pin 4. The other pole of the attraction magnet 7 whose magnetic pole is different from that of the magnet 6 provided at the tip of the guide pin 4 is made the same pole as the magnet 6 on the guide pin 4 side, and the guide pin 4 is retracted below the floor. The repulsion magnet portion 9 is formed (see FIG. 1).

When the guide pin 4 reaches the end of the running groove 5, however, the magnet portion 9 for repulsion presses the guide pin 4 below the floor surface and pushes the guide pin 4 completely into the outer cylinder 12. It is something to keep. Thus, the magnet 6 is provided on the upper end portion of the guide pin 4, and the magnetic body M for magnetically holding the guide pin 4 via the magnet 3 is provided on the hanging door body 3 side. The guide pin 4 is held by a cylindrical case 12 buried below the surface so as to be vertically movable, and when the guide pin 4 is released from the magnetic attachment by the magnetic attachment M on the side of the hanging door body 3, the guide pin 4 is moved by its own weight. The guide pin 4 is dropped and stored in the cylindrical case 12, and therefore the guide pin 4 is moved upward through the magnet 3 at the head of the guide pin 4 due to, for example, a suction action of a cleaner or movement of various metal pieces. Even if it is pulled up, the vacuum cleaner passes and the suction force is released, or when the magnetic attachment is released, the guide pin 4 falls by its own weight and the tubular case 1
Since it is stored in the guide 2, the guide pin 4 does not unexpectedly remain protruding.
