The tray 2 has a pair of second side walls 21 disposed opposite to each other in the lateral direction, and the first roller 3 is connected to the outside of the second side walls 21 in the lateral direction.

As shown in fig. 7, each of the first rollers 3 includes a wheel body 31, a fixing member 32 for fixing the wheel body 31 to the wheel body, and a damper ring 34 mounted on the wheel body 31, and a groove 312 for accommodating the damper ring 34 is concavely formed on an outer circumferential surface of the wheel body 31.

As shown in fig. 5 and 7, the tray 2 further comprises a pair of supporting walls 212 protruding on the outer surface of the corresponding second side wall 21, and a plurality of reinforcing ribs 213 connected to the supporting walls 212, wherein each supporting wall 212 extends along the front-rear direction, the plurality of reinforcing ribs 213 are arranged along the front-rear direction, and each reinforcing rib 213 is perpendicular to the supporting wall 212.

In addition, each of the second side walls 21 further has a first mounting portion 214 protruding from an outer wall surface thereof, and the first mounting portion 214 has a mounting hole 2141 extending in a lateral direction for mounting the first roller 3. In this embodiment, the fixing member 32 is a threaded fastener, and extends into the mounting hole 2141 after passing through the through hole on the wheel body 31, so as to fixedly connect the first roller 3 to the outer side of the tray 2.

A pair of second rollers 4 are connected to the inner side of the first side wall 12 of the drawer 1, and the pair of support walls 212 rest on the second rollers 4 and enable the second rollers 4 to slide back and forth along the corresponding support walls 212.

Each first side wall 12 is provided with a yielding zone 121 formed by outwards sinking from the inner surface of the first side wall, a step surface 122 for limiting the yielding zone 121, and a limiting wall 123 positioned on the upper side of the step surface 122, wherein the limiting wall 123 is positioned in the yielding zone 121 and forms the slideway 120 with the step surface 122 along the height direction at intervals.

In the present invention, the second roller 4 is positioned at the rear side of the stopper wall 123 and above the stepped surface 122.

Each first side wall 12 is further provided with a stop wall 124 located at the front side of the stop wall 123 and connecting the stop wall 123 with the step surface 122, the stop wall 124 is an arc wall that arches forward, when the drawer 1 is in a closed state, the first roller 3 is stopped by the stop wall 124 at the same side, so as to prevent the first roller 3 and the tray 2 fixedly connected by the first roller 3 from sliding forward.
