The present invention relates to a delivery mechanism for freely moving the angle of the delivery and can lean forward and can lean back in the back position to more easily distribute the weight of the left leg. Swing delivery chairs are not mechanical and can be fatigued because they are not laid back. The swinger comes out, but it does not become a prone position, so it does not become a squatting posture. You can adjust the angle of the delivery chair, but it is very power consuming and not free to adjust the angle of the chair. The upper and lower support structures are fixedly connected to each other, and the lower support structure has a delivery hole so that this part can swing and move the delivery person's angle freely and lean forward. It can also be a good way to distribute weight so you can have more comfort. This can be moved along the rail to rotate the rollers to move the upper and lower body support parts so that the angle can be changed smoothly or manually. If you do this, you can lean forward naturally and smoothly like a rocking chair.
