To provide nursery equipment whose movable portion can be adjusted in position or shape by a simple structure.SOLUTION: An adjustment mechanism (3H) of nursery equipment includes a string (4) connecting a fixed portion and a movable portion, a reel (80) that is rotatable in both forward and reverse directions and that changes the position or shape of the movable portion by winding up and feeding out the string (4), a biasing member (110H) that biases the reel (80) in such a way that it rotates in a winding direction of the string (4), and a lock member (70c) that prohibits rotation of the reel (80). A biasing force of the biasing member (110H) is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.SELECTED DRAWING: Figure 33
【課題】簡易な構造で可動部の位置または形状を調節することが可能な育児関連器具を提供すること。【解決手段】育児関連器具の調節機構(3H)は、固定部と可動部とを連結する紐(4)と、正逆両方向に回転自在であり、紐(4)の巻き取りおよび送り出しによって、可動部の位置または形状を変化させるリール(4)と、リール(4)を紐(4)の巻取り方向に回転するように付勢する付勢部材(110H)と、リール(4)の回転を禁止する回転ロック部材(70C)とを備える。付勢部材(110H)の付勢力は、可動部が鉛直方向下方に移動しようとする付勢力よりも小さくなるように選ばれている。【選択図】図33
