In the illustrated example, the locked surface of the hooking projection 36 is configured to be approximately parallel to the step wall surface of the locking step 16 when the hooking projection 36 is locked to the locking step 16. It shows. In other words, the locked surface of the hook projection 36 is an inclined surface that faces diagonally downward when the hook projection 36 is locked to the lock step 16. With this configuration, the locking strength of each of the hooking protrusion 36 and the step wall surface of the locking stepped portion 16 can be improved compared to a case where the locking surface of the hook projection 36 and the step wall surface of the locking stepped portion 16 are vertical surfaces facing in the depth direction of the shelf board. I can do it.

The hook protrusion 36 also has an inclined guide surface that displaces the hook protrusion 36 side of the hook member 33 toward the lower side, which is the other side in the shelf thickness direction, when the hook comes into contact with the opening edge of the holding groove 13. 36a is provided. With this configuration, when inserting the above-mentioned clamped piece 38 into the holding groove 13 from the distal end side, the hooking member 33 can resist the biasing force of the biasing member 32 due to the guiding action of the inclined guide surface 36a. The shelf board 20 can be rotated with ease, and the ease of attaching the shelf board 20 can be improved. Further, the inclined guide surface 15 provided on the opening edge side of the holding groove 13 described above is an inclined guide surface that displaces the hooking protrusion 36 side of the hooking member 33 downward when the hooking protrusion 36 comes into contact with it. Configure. With such a configuration, the hook member 33 can be more smoothly displaced by the guiding action of the mutually provided inclined guide surfaces 15 and 36a. Note that instead of the embodiment in which the inclined guide surfaces 15, 36a are provided on both the opening edge of the holding groove 13 and the hook projection 36, it may be provided on either one of them, and furthermore, such an inclined guide surface 15, 36a may be provided on either one. A configuration may be adopted in which guide surfaces are not provided on both sides.

Further, as shown in FIG. 3(a), when the hook protrusion 36 and the hook main body part 35 are recessed, the hook protrusion 36 and the hook main body part 35 are connected to the shelf board thickness of the hook holding part 31. It is provided so as not to protrude from both sides in the thickness direction of the shelf board.
In the present embodiment, the shelf board 20 is provided with an operating section 37 on the hook member 33 that rotates the hook member 33 around the hook shaft 34 so as to displace the hook protrusion 36 side of the hook member 33 downward. The structure is such that it is exposed on the back (lower) side. With such a configuration, by operating the operating portion 37, the hooking member 33 can be rotated against the biasing force of the biasing member 32, thereby preventing the hooking protrusion 36 from locking with the locking step portion 16. It can be canceled. Thereby, the shelf board 20 can be easily detached from the support member 10.

The operating portion 37 includes an extending portion provided to extend downward from the front side portion of the hooking shaft 34 in the hooking member 33, and an operating portion protruding forward from the lower end of this extending portion.

In this embodiment, the operating portion 37 is configured to be operated within the recess 23 so as not to protrude from the lower surface of the shelf body 21.
When the operation piece of the operation part 37 is operated against the bias of the bias member 32 so as to be pushed upward, the hook protrusion 36 is retracted as shown in FIG. 3(a). A hook member 33 rotates around a hook shaft 34 on the side. As a result, the locking of the hook protrusion 36 with respect to the locking step portion 16 is released, and the shelf board 20 can be detached from the support member 10. Furthermore, when the external force pushing up the operating portion 37 upward is removed, the biasing member 32 rotates the hooking member 33 around the hooking shaft 34 to the side where the hooking protrusion 36 projects. Note that the operation section 37 is not limited to the configuration described above, and various other modifications are possible.
