When the door 30 is completely closed, the latching jaw 12 is retained in the latching portion 52 of the damper 50.

4B through 4C and 5 illustrate the door 30 in a closed state and when the door 30 reaches a certain point where the door 30 is closed the speed adjusting damper 50 The engagement protrusion 57 of the engagement protrusion 57 touches the engagement protrusion 12 completely and the engagement protrusion 58 inserted in the engagement protrusion 53 is released , The door 30 is automatically closed by the elastic force of the spring 55 which has been maximally extended, and the damper rod 54 is gradually inserted into the cylinder.

When the damper rod 54 enters the cylinder, it functions as a buffer to reduce the closing speed of the folding door 30 due to the damping liquid pressure contained in the cylinder. Therefore, even if the door 30 is strongly closed, the door frame is automatically closed by the elastic force at a certain point at which the door frame is completely closed, so that an uncomfortable feeling such as shock or noise is not generated.

For this purpose, the speed control damper 50 fixed to the slider passage 11 of the upper chassis 10

And a damping rod 54 which is horizontally connected to the locking part 52 and reciprocates in a cylinder is attached to the locking part 52. An elastic spring 55 is vertically spaced from the locking part 52, So that the elastic force is activated when the portion 52 reciprocates,

The elastic force of the elastic spring 55 is increased to apply an elastic force to the damper 50 and to prevent the door 30 from being opened rapidly when the folding door 30 starts to be opened in a completely closed state, In addition,

When the door 30 is closed, the elastic force is restored and automatically closed so that the closing speed of the door 30 is buffered by the damping function of the damping rod 54 due to the damping liquid pressure in the cylinder. .
