The present invention relates to a child-rearing-related device capable of adjusting the position or shape of a movable part with a simple structure. This adjustment mechanism (3H) for a child-rearing-related instrument is provided with: a cord (4) that connects a fixed part and a movable part; a reel (4) that is rotatable in both forward and reverse directions and that changes the position or shape of the movable part by winding and unwinding the cord (4); a biasing member (110H) that biases the spool (4) so as to rotate in the winding direction of the cord (4); and a rotation lock member (70C) that prohibits rotation of the spool (4). The urging force of the urging member (110H) is selected so as to be smaller than the urging force by which the movable part is to move downward in the vertical direction.
本发明涉及育儿相关器具,其能够以简单的结构调节可动部的位置或形状。本发明的育儿相关器具的调节机构(3H)具备:绳(4),其连结固定部和可动部;卷轴(4),其在正反两方向上旋转自如,通过绳(4)的卷绕及送出,使可动部的位置或形状变化;施力部件(110H),其以使卷轴(4)向绳(4)的卷绕方向旋转的方式施力;以及旋转锁定部件(70C),其禁止卷轴(4)的旋转。以比可动部欲向铅垂方向下方移动的作用力小的方式选择施力部件(110H)的作用力。
