Background
Since the body development of infants is not complete from birth to the infant, a variety of devices are required to assist life. For example, a baby carriage which helps a parent to move and reduce the burden of holding a baby for a long time is an important tool for a baby or a child during a period when the baby is out of the way, who is not walking yet or is in a learning stage.
One of the functions most appreciated by the guardian is whether the stroller is collapsible. When unfolded, the stroller is very bulky, and therefore, if it cannot be folded and downsized, it not only occupies a large space when stored at home, but also is difficult to put into a car trunk or use public transportation when going out or carrying.
The conventional stroller has a folding function, but the folding operation is clumsy and requires many steps to achieve the folding operation, so that there are disadvantages that the folding operation is complicated and the folding is not smooth.
