Since the direction of the line connecting the second engaging portion 17 and the first engaging portion 17 substantially coincides with the forward / backward movement direction of the drawer 5, even if the drawer 5 is to be pulled out in this locked state, the pulling force of each drawer 5 causes the drawer 5 to engage. The stop piece 13 does not come off the first engagement portion 17 or the drawer 5 does not twist. In addition, if the engagement hole 55 between the bell crank lever 40 and the second interlocking rod 37 is formed as a long hole, and the urging force of the third spring 47 is made larger than the urging force of the second spring 33, Even if the push-in lock 7 is locked while any drawer 5 is pulled out, a so-called kicking lock that can be locked at the same time as the drawn-out drawer 5 is pushed in is possible.

Even in the locked state, the second interlocking rod 37 can move rightward against the force of the third spring 47 by pressing the first interlocking rod 36 rightward. In FIG. 3, when the drawer 5 is pushed in after being locked with the optional drawer 5 pulled out, the drawer 5 is locked by the first engagement portion 17 with the pushing motion (the direction of the arrow (a)). The front of the piece 13 is moved to the first
By pressing against the force of the spring 32, the locking piece 13 is rotated in the counterclockwise direction, and at the same time, the vertical axis 12 is rotated in the clockwise direction by the urging force of the first spring 32. The locking hooks 14 of the locking pieces 13 are fitted and locked in the first engaging portions 17, and all the drawers are locked.

となり、組立作業を迅速且つ簡単に行える。As described above, in the configuration of the present invention, the first interlocking rod is connected to the swing lever that rotates integrally with the longitudinal axis that is common to the all-lock operation and the double pullout prevention operation. Then, the first pressing portion of the first interlocking rod and the second pressing portion of the second interlocking rod are arranged facing each other,
At the time of the locking operation of the push-in lock, the first interlocking rod is forcibly moved forward by the second interlocking rod via the two pressing portions, and the longitudinal axis rotates in the locking direction. There is no imperfections such as engagement and disengagement with the swing lever by the technical cam and roller, and fine adjustment is not required for the mounting operation, so that the assembly operation can be performed quickly and easily.

きるという効果を奏する。Further, when the push-in lock is unlocked, the first pressing portion and the second pressing portion are separated from each other, and the engaging hook portion of the elastic body of the second interlocking rod is in the first interlocking member. Since the engagement with the locking portion is released, the first interlocking rod can freely move left and right, so that the first interlocking rod moves with the left and right rotation of the swing lever independently of the second interlocking rod in a stationary state. Therefore, there is an effect that the double drawer preventing operation can be reliably performed.
