This is because the tray receiving member 3 is used as a left and right common member.

Next, a second embodiment will be described with reference to FIGS. The second embodiment is different from the first embodiment in that the horizontal support protrusions 5 are provided.
The horizontal support ridge 300 which is close to the upper end of the upward ridge 51 of the tray 2 instead of 21 is attached to the mounting portion 30 of the tray receiving member 3.
When the first stopper 53 collides with the rear end of the stopper receiver 311 and the upper end of the rear plate portion 24 of the tray 2 is
The tray is supported in a substantially horizontal posture by abutting on the tray.

Since the present invention is formed as described above,
The state in which the tray 2 is stored on the lower surface of the top plate 14 (as shown in FIG. 1, the lower surface of the second stopper 52 contacts the upper surface of the support ridge 31, and the lower surface of the outward protrusion 51 When the tray 2 is pulled out from the state (contact with the upper surface), the first stopper 53 collides with the rear end of the stopper receiver 311 and temporarily stops. In this state, the outward ridge 51
The bottom surface of the tray 2 comes into contact with the top surface of the stopper receiver 311, the rear portion of the tray 2 rises slightly due to the weight of the front end of the tray 2, and the top surface of the horizontal support protrusion 521 abuts the bottom surface of the mounting portion 30 (in the second embodiment, the tray 2 The upper end of the rear plate portion 24 abuts against the horizontal support ridge 300) to maintain the tray 2 in a substantially horizontal posture (the state shown in FIGS. 4 and 6), and to use the tray 2 stored in the front half of the tray 2. Frequently used items can be used. That is, even if the drawer operation is frequently performed, the movement is temporarily stopped, so that the possibility that the tray 2 is suddenly pulled out and the tray 2 falls can be avoided.

In order to remove the infrequently used articles stored in the rear part of the tray 2 or to check the stored articles, the front plate 2
1 is slightly lifted, and the tray 2 is pulled out forward while maintaining the state where the first stopper 53 is positioned above the stopper receiver 311.
