After the rib 120 is elastically deformed by the second protrusion 57, the stopper 111 is caught by the second locking portion 53 and the drawer 100 may be stopped. That is, just before the stopper 111 is caught by the second locking portion 53 and the drawer 100 is stopped, the rib 120 is elastically deformed by the second protrusion 57 so that the user can perceive it. there is.

When the drawer 100 is retracted from the drawn-out state, the rib 120 may be elastically deformed by the second protrusion 57 and then elastically deformed by the first protrusion 55. After the rib 120 is elastically deformed by the first protrusion 55, the stopper 111 may be caught by the first locking portion 51 and the drawer 100 may be stopped. That is, just before the stopper 111 is caught by the first locking portion 51 and the drawer 100 is stopped, the rib 120 is elastically deformed by the first protrusion 55 so that the user can perceive it. there is.

Since the rib 120 is damped by contacting the plurality of protrusions 55 and 57 before the stopper 111 is caught by the catching portions 51 and 53 and the drawer 100 stops, the user cannot recognize this. there is. In other words, before the drawer 100 stops, the user can recognize that the drawer 100 will soon stop, so emotional quality can be improved. In addition, because the user can recognize this before the drawer 100 is maximally retracted and withdrawn, the user can ensure that the drawer 100 is seated in the correct position when maximally retracted and withdrawn without using excessive force. You can. In addition, in the drawer 100, in addition to the two parts where the stopper 111 is caught and restrained by the catching portions 51 and 53 during retraction and withdrawal, the rib 120 is damped by a plurality of protrusions 55 and 57. Two parts can be added that are constrained. Through this, the drawer 100 can be prevented from being distorted during retraction and withdrawal. Accordingly, there may be no need for a separate member to prevent the drawer 100 from being distorted.
