Next, the height of the upper fence 3 is adjusted downward so that the upper fence 3 is moved downward from the first lowered position shown in FIG. 15 and positioned in FIG. A second lowered position is shown, at which time the height of the upper crossbar 31 is lower than the height of the bed 11 and the upper fence 3 does not block the bed 11 at all. Thereby, the caregiver can be prevented from being obstructed by the upper fence 3 during the process of caring for the baby or holding or placing the baby, so that the caregiver can perform the aforementioned actions with difficulty and convenience. It should be noted that since the operation process of the locking mechanism 4 is the same as that of the previous paragraph, it will not be described in detail in this paragraph.

As shown in FIG. 5, FIG. 16, FIG. 17, and FIG. 18, when the lower fence 2 and the upper fence 3 are to be detached from the slide rails 122 of the two columns 12, the lower fence 2 needs to be adjusted downward to the position shown in FIG. Position, at this time, the lock pin 42 of the lower fence 2 is locked at the lowest positioning hole 126. Next, the lower crossbar 1 is lifted for a short stroke to move the flange 422 of the lock pin 42 of the lower fence 2 upward to release the buckled state with the base wall 123 of the slide rail 122. Then, the pressing portion 441 of the release button 44 of the lower fence 2 is pressed to move the release button 44 downward in the pushing direction IV, and the release button 44 is pushed through the pushing surface 443 during the movement in the pushing direction IV.
