Then, the wiring 10 can be flexibly deformed along the surface of the panel member 5 on the top plate 4 side in a restricted space in which the movement of the wiring 10 due to the flexural deformation is restricted. Specifically, the regulation space has a wiring insertion space 62 surrounded by the attachment portion 82 and the bent portion 84 of the regulation member 80 as a locking space, and is defined by a space determined by the degree of flexural deformation of the wiring 10. ing. In this way, the range in which the wiring 10 moves due to the bending deformation is restricted within the restriction space above the top plate 4, so that the wiring 10 is moved above the top plate 4 with the top plate 4 in the lowest position. The wiring 10 extending above the top plate 4 can be maintained close to the panel member 5C at least in the state where the top plate 4 is located at the lowest position. It can be prevented from falling.

Although the preferred embodiments of the present invention have been described above in detail, the present invention is not limited to the above-described embodiments, and various modifications and alterations are possible within the scope of the gist of the present invention described in the claims. It can be changed.

For example, the furniture with the lifting ceiling plate of the present invention is not limited to the ceiling plate lifting type desk such as the writing table, but can be applied to other appliances with the lifting ceiling plate other than the desk.

In addition, the regulation member 12 in the top-panel lifting desk 1A of the first embodiment or the regulation member 80 in the top-panel lifting desk 1B of the second embodiment matches the position and movement of the wiring 10 and the top panel 4 and the panel member. It may be provided on the surface of the panel member 5A or the panel member 5B on the top plate 4 side so as to fit in the gap between the panel member 5A and the panel member 5B.

Further, in the top-lifting desk 1A of the first embodiment or the top-lifting desk 1B of the second embodiment, the locking portions may be provided separately in the lateral direction of the regulating member 12 panel member 5C. .. According to such a configuration, when the wiring 10 is flexibly deformed in response to the elevation of the top plate 4, the wiring 10 is locked by the locking portions at the positions separated in the left-right direction in the restricted space. The range in which 10 is flexibly deformed can be restricted in the left-right direction, and can be flexibly deformed in a stable state. Therefore, it is possible to favorably prevent the wiring from falling to the user side.
However, for example, in the top-and-bottom type desk 1A of the first embodiment, the locking portions 16 and 75 are provided on the right side when viewed from the front side, but the locking portions provided on the protruding portion 47 of the wiring support portion 44B. Since the portion 70 is provided on the left side when viewed from the front side, the wiring 10 can be flexibly deformed in a stable state.

Although not shown in the drawings, in the regulating member 80 of the top-and-bottom-type desk 1B of the second embodiment, for example, at both ends in the left-right direction of the mounting portion 82, from one end to the front (that is, the top plate). The pair of bent portions may be provided so as to be opposed to the mounting portion 82 and protrude toward the other end portion after protruding toward the other side, and the tips of the bent portions may be separated from each other. With such a configuration as well, it is possible to obtain the same operational effects as the operational effects of the top plate elevating desk 1B of the second embodiment.
