An adjustment mechanism of nursery equipment includes a string connecting a fixed portion and a movable portion, a reel 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, a one-way clutch mechanism that allows rotation of the reel in a winding direction of the string and prohibits rotation of the reel in a feeding direction of the string, and an unlock member that unlocks the reel from a rotation prohibited state caused by the one-way clutch mechanism and thus allows the reel to rotate freely

Nursery equipment includes: a body (car seat body); an extended portion (ISOFIX) extended from the car seat body; and an adjustment mechanism for adjusting the position or shape of the ISOFIX. The adjustment mechanism includes a string having one end connected to the car seat body and the other end held by the ISOFIX, a reel that is rotatable in both forward and reverse directions and that changes the position or shape of the ISOFIX by winding up and feeding out the string, and a rotation lock mechanism that prohibits rotation of the reel.

An adjustment mechanism of nursery equipment includes a string connecting a fixed portion and a movable portion, a reel 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, a biasing member that biases the reel in such a way that the reel rotates in a winding direction of the string, and a lock member that prohibits rotation of the reel. A biasing force of the biasing member is selected to be smaller than a biasing force with which the movable portion tends to move downward in the vertical direction.

An adjustment mechanism of nursery equipment includes a string connecting a fixed portion and a movable portion, a reel 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, a rotation operation member that controls rotation of the reel, a motion transmission portion that transmits a rotational motion of the rotation operation member to the reel, and a motion separation portion that does not transmit the rotational motion of the rotation operation member to the reel.

The present invention provides a metal strip coil that can suppress a shape failure at an end portion of the coil. A metal strip coil including a metal strip wound around a winding core, wherein the metal strip is wound from one end side toward the other end side of the winding core, turns back at the other end portion, is wound from the other end side toward the one end side of the winding core, turns back at the one end portion, and is repeatedly wound in such a manner, wherein in the turnback, the metal strip has a turnback portion at which the metal strip is wound in a direction perpendicular to the axial direction of the winding core, in a side view of the metal strip coil, the turnback portion is arcuate, and the turnback portions are formed in a multistage manner from the inner circumference toward the outer circumference, and a line connecting a midpoint of the arcuate arc with the center of the arc is formed so as to rotate stepwise in one direction, in an order of the arcuate turnback portions which are formed in a multistage manner from the inner circumference to the outer circumference.
