To a reciprocating device.

Generally, in order to make the infant's sleep easier or to stop the infant crying with a device such as a baby carriage, a cradle, etc., which can carry a baby (hereinafter referred to as a baby carriage) Or shake it. Moreover, if you do not have enough space to haul your stroller, or if you need to stay in a limited space such as meals, gatherings, etc., you can not drag the stroller, so you must keep the stroller back and forth in place. Therefore, it is very uncomfortable for a person putting on or taking care of a baby in a baby carriage, and it is also difficult to obtain the effect of putting or comforting a baby because the baby carriage can not be shaken sufficiently.

Of course, as shown in the following patent document, an electric motor-driven baby carriage has been developed. However, the electric baby stroller is required to be equipped with a large-capacity battery due to high power consumption when driving on the road, There was a part that did not. In addition, the electric stroller is not widely used because it is very expensive.
