초록 ▼

Disclosed is a foldable baby playyard having improved bottom foldable hub member and foldable rail joint connecting members. The improved structure of the foldable hub member and the foldable rail joint connecting members enable the playyard to be conveniently and quickly collapsed and folded to occupy a room as small as possible. On the other hand, the playyard can also be quickly extended again from the folded state to be safely used by a baby without the risk of becoming unexpectedly collapsed or unstably swayed due to any force applied to the foldable hub member and/or the foldable joint connecting members by the baby in the playyard.
