た。In the conventional elevator door apparatus as shown in FIG. 6, when the sliding door 4 is fully closed, a door opening force is generated by the weight of the link mechanism 12. Therefore, when the power of the elevator is cut off, there is a danger that the sliding door 4 is opened by itself from the fully closed state due to the opening force of the link mechanism 12 due to its own weight. And the inclination of the cam 12d is used to obtain the door-closing holding force for performing the fully-closed holding. However, in order to smoothly open and close the door, it is necessary to avoid a sudden change in the urging force applied to the sliding door 4, and the inclination of the cam 12d is naturally limited, so that the spring elasticity of the urging body 11 is sufficiently increased. Needed. As a result, it is necessary to improve the strength of the door device, which causes a problem that the manufacturing cost of the device is increased.

The rail 5e presses the right inclined portion of the chevron 19a. When the sliding door 4 starts to open, the roller 5e moves to the biasing body 1
4 and moves over the upper end of the chevron 19a while pressing against the right inclined portion of the chevron 19a against the pulling force of No. 4. The parallel link 5c rotates counterclockwise around the contact portion with the engagement device 5, and the movable member 5b simultaneously rotates the parallel link 5c.
It rotates counterclockwise around a contact portion between the c and the engagement device 5. Further, when the sliding door 4 is opened, the roller 5e is moved to the angled section 1.
It moves while pressing the left inclined portion of 9a. Roller
When 5e has gone down the left inclined portion of the chevron 19a, the movable member 5b and the fixed plate 5a are in a state of gripping the engagement element 10. Thereafter, the roller 5e moves along the chevron cam 19 with the movable member 5b and the fixed plate 5a gripping the engaging element 10. (B) in all open front of the sliding door 4 - La -5e Yamagata portion 19b
At this time, it separates from both the movable member 5b and the fixed plate 5a, and the engaging element 10 is in a non-grip state. Thereafter, the roller 5e moves at the upper end of the chevron 19b.
And sometimes the entire opening of the sliding door 4, is pulled by the biasing member 14 b - La -5e is located in a state of pressing the left inclined portion of the mountain-shaped portions 19b. Therefore, with the simple configuration as described above, when the sliding door 4 is fully closed, it is urged in the door closing direction,
When fully opened, the door is urged in the door opening direction, and a smooth opening / closing drive action of the sliding door can be obtained.
