As shown in FIGS. 2 and 3, the sliding member (14) is made of an elastic synthetic resin having a small friction coefficient and having a large number of ridges (14a) on its surface along the length direction. It is preferably used. As described above, in the case of using the material having elasticity, the other supporting leg plate (4) is forcibly fitted against the elastic force of the sliding members (14) and (14) so that there is no backlash. The reason is that the one having a large number of ridges (14a) along the length direction on the surface and having a small friction coefficient is used.
This is to enable smooth lifting operation even in the above-mentioned forced fitting state. Further, in the illustrated embodiment, as shown in FIG. 2, a sliding member (14) similar to the above is fixed to the surface other than the facing surface of the guide portion (12a), and the supporting leg plate (4) is attached.
It prevents backlash in the left and right directions. However, in this invention, the number, material, shape, etc. of the sliding members (14) are not particularly limited as long as the sliding members (14) are fixed along the height direction to the inner surfaces of the guide portion (12a) facing each other. Not something.

In the above embodiment, the top plate (2) has the slide hole (1c).
Is attached to the upper end of one supporting leg plate (1) (1) formed with the supporting leg plate (1) (1) and the other supporting leg plate (4)
Although the thing which goes up and down with respect to (4) was shown, this invention is not limited to this, conversely, the top plate is attached to the supporting leg plate inserted into the slide hole portion, and the supporting leg plate is the other one. It can also be applied to a learning desk that is designed to move up and down with respect to the supporting leg plate.

Moreover, both of the supporting leg plates (1), (1), (4), and (4) are made of wood that is difficult to obtain dimensional accuracy, and the guide portion having a U-shaped cross section is provided in the slide hole portion (1c). (12
Since the slide guide plate (12) having a) is attached, the size of the hole (1c) can be made substantially accurate, and the guide (12a) faces each other. A strip-shaped sliding material (14) (14) made of a synthetic resin having elasticity along the height direction is fixed to the inner surface of the sliding surface.
Between the two supporting leg plates (1) and (4), the other supporting leg plate (4) is forcedly fitted between the two supporting leg plates (1) and (14) against the elastic force of the sliding members (14) and (14). It is possible to eliminate the gap that occurs in the above, and thus it is possible to make it a wooden learning desk that is in line with the consumer's orientation but is free from rattling.

Moreover, both supporting leg plates (1) constituting the telescopic legs (5)
(4) As a member for finely adjusting the fitting of the thrust, a strip-shaped sliding member (14) ( 14) is used, so even if the desk is subjected to excessive stress, the other supporting leg plate (4) has a recessed portion corresponding to the protruding member as in the conventional product. It is possible not only to avoid the inconvenience of being formed, but also to reduce the frictional resistance and realize a smooth lifting operation for a long period of time, the configuration is also extremely simple, suitable for mass production, and easy to assemble. It is possible to reduce the cost of the product.
