Description of the Related Art Conventionally, in office spaces such as offices, hospitals, and public facilities, for example, an electronic device or the like is used, and a mobile fixture that can travel on a floor surface is used (see, for example, Patent Document 1). Since the mobile fixture can be moved together with the office worker in the office space, it is possible to improve the efficiency and convenience of the office.
Since the moving fixture has a possibility that an article placed on the top plate may fall when moving, a fall prevention member for preventing the article placed on the top plate from falling is an edge of the top plate. It may be provided in the vicinity of the part so as to protrude upward.

特許文献１に開示された移動式什器は、第１天板と、第１天板の上方に間隔をあけて配置される第２天板と、第１天板に対して第２天板を前後方向にスライド可能に支持する支持部材と、を有している。支持部材は、第１天板の両側縁部から上側に突出し、上端部に第２天板が連結されているとともに、第１天板に対して前後方向にスライド可能に構成されている。このような支持部材は、第１天板の両側縁部から上側に突出しているため、第１天板に載置された物品が側方に落下することを防止できる。   The movable fixture disclosed in Patent Document 1 includes a first top plate, a second top plate disposed above the first top plate with a space therebetween, and a second top plate with respect to the first top plate. And a support member that is slidably supported in the front-rear direction. The support member protrudes upward from both side edge portions of the first top plate, the second top plate is connected to the upper end portion, and is configured to be slidable in the front-rear direction with respect to the first top plate. Since such a support member protrudes upward from both side edge portions of the first top plate, it is possible to prevent the article placed on the first top plate from falling sideways.
