) is tilted, the door body (1) slides down in the opening direction.
扉本体（１）は、案内支持杆（２）の傾動だけでも自走
開閉が可能であるが、傾斜角度が小さいと、動き初めの
速度が小さく、開閉動作の速やかな反応が得られない。The door main body (1) can be opened and closed by itself by simply tilting the guide support rod (2), but if the inclination angle is small, the initial speed of movement is low and a quick response in opening and closing operations cannot be obtained.

速度を与える。Therefore, when magnetic levitation is completed and the guide support rod (2) is tilted, the magnetic field generated by the electromagnet (14)
A current is rapidly increased to the electromagnet (14) so as to strongly repel the permanent magnet (12), causing the door body (1) to repel the electromagnet (14) fixed to the wall (3a). This gives the door body (1) an initial speed for inertia running and for sliding down the slope.

When the door approaches the wall (3b), it is detected by the door detection sensor (
16) group, and actuates the electric actuator (8) according to the detected position of the door detection sensor (16), and operates the electric actuator (8) side end (7) of the guide support rod (2).
) is made higher than the horizontal position and the inclination angle of the guide support rod (2) is reversely inclined.
扉本体（１）の自走力の制動には、案内支持杆（２）の
逆傾斜と、電磁石（１４）の反発力作用の両方を、同時
に行なってもよい。To brake the self-propelling force of the door body (1), both the reverse tilting of the guide support rod (2) and the repulsive force action of the electromagnet (14) may be performed simultaneously.

開閉装置。(2) A magnetic levitation means provided at the top of the door body is electromagnetically linked to a guide support member made of a magnetic material, so that the door body is levitated from the guide support member and moved in the left and right direction without contact. In the magnetic levitation type sliding door device, an electromagnetic repulsion means consisting of a set of a permanent magnet and an electromagnet is installed between both edges of the door body in the opening/closing direction and the corresponding wall surfaces that the two edges abut on each side when the door body is opened/closed. By controlling the electromagnetic repulsion force of the electromagnetic repulsion means, the sliding door is opened and closed by accelerating or decelerating the speed at which the door body moves by itself along the guide support member. Floating sliding door opening/closing device. (3) The magnetic levitation means provided at the top of the door body is electromagnetically linked to the guide support member made of a magnetic material, so that the door body is levitated from the guide support member and moved in the left and right direction without contact. In the magnetically levitated sliding door device, one end of the guide support member is pivoted so as to be rotatable around a horizontal axis, and the other end is also supported so as to be movable up and down with an electric actuator, and the opening/closing direction of the door body is supported. An electromagnetic repulsion means consisting of a set of a permanent magnet and an electromagnet is provided between both side edges of the door body and a corresponding wall surface that the both side edges contact with each other when the door body is opened and closed, and the inclination angle of the guide support member is changed by the electric actuator. and by controlling the electromagnetic repulsion force of the electromagnetic repulsion means, the speed at which the door body moves by itself along the guide support member is accelerated or decelerated, thereby opening and closing the sliding door. Magnetic levitation sliding door opening/closing device.
