It is composed of a bolt 33 having a head and a nut 34.

Explaining the relationship between the guide groove 16 and the pin 20, the guide groove 16 may be linear along the step edge 13, but in the case of the counter mode, the counter plate 3 is rotated. In order to optimize the position by moving the table plate 2 along the depth direction of the table plate 2 while being supported by the tip end edge 9 of the plate 4, the guide groove 16 extends from the tip end 17 to the tip end edge 9. It is also possible to use an L-shaped groove in which an auxiliary groove 35 that extends slightly along is formed. When the pin 20 is located in the auxiliary groove 35, the counter plate 3 does not rotate about the pin 20, and the counter plate 3 can be prevented from rotating unexpectedly. Further, as shown in FIG. 6, the guide groove 16 is formed by embedding a guide metal fitting 36 having a substantially C-shaped cross section in the rotary plate 4, and the shape of the pin 20 projecting on the projecting piece 19 is changed to the guide metal fitting. It is preferable to have a head so that the groove 36 can be fitted in the groove having a substantially C-shaped cross section in a state where it is prevented from coming out laterally. Further, in the present embodiment, the projecting piece 19 is composed of the L-shaped metal fitting, but it goes without saying that a wooden member may be used.

Next, a structure for stably maintaining the counter mode and the table mode will be described. First, as described above, in the counter mode, the one side edge 10 of the base end portion of the rotating plate 4 is abutted against the rising edge 11 of the notch recess 8, as described above. Pivoting the part 5 into the recess 8 is very unstable. Therefore, the pivotal position of the bearing 31 is closer to the base end other side edge 14 side than the center of gravity line in a state where the rotating plate 4 stands up and the counter plate 3 is mounted on the tip end edge 9 thereof. It is eccentric to stabilize. However, with this alone, the counter plate 3 suddenly
Since there is a risk of rotation when a lateral force is applied to the stopper, the stopper device 37 is provided in this embodiment so that the state can be reliably fixed.

The position of the engaging hole 42 is provided at a position corresponding to the engaging portion 40 on the inner surface of the rotating plate 4 in the upright state.

In the table state, the rotating plate 4
It is as described above that the other side edge 14 of the base end portion of the base plate abuts against the horizontal edge 15 of the cutout recess 8 and maintains that state. Since the side edge 14 and the horizontal edge 15 collide with each other, a large noise may be generated due to the impact, and a rotating portion or the like may be damaged. Therefore, a shock absorber 43 is provided at the end of the horizontal edge 15 so as to project. There is. However, in the state in which the other edge 14 of the base end portion is in contact with the cushioning tool 43, that is, in the state of the table mode, when the unexpected lifting force acts on the counter plate 3 or the rotating plate 4, the rotating plate 4 Since there is a possibility that the counter plate 3 may rattle when it is rotated upwards, in order to maintain this state securely, the counter plate 3 should be positioned at the position corresponding to the engaging portion 40 on the inner surface of the tilted rotating plate 4.
