When the table 2 is raised to the use position as shown in FIG. 2, the large-diameter shaft portion 6a of the lock shaft 6 supported by the movable support plate 3 engages with the lock hole 10 of the fixed base plate 4. This engagement state is maintained by the urging movement of the spring 8. Therefore, the movable support plate 3 cannot be rotated downward about the horizontal pivot 5, and the table 2 is stably secured at the horizontal position. When the lock shaft 6 is pushed in the axial direction after the use of the table 2 against the bias of the spring 8, the large diameter shaft portion 6a escapes from the lock hole 10 and the small diameter shaft portion 6b enters the lock hole 10. As a result, the lock of the movable support plate 3 with respect to the fixed base plate 4 is released. Therefore, when the lock shaft 6 is kept pressed, the table 2 rotates downward by its own weight. With this rotation, the small-diameter shaft portion 6b of the lock shaft 6 apparently moves in the escape hole 11 of the fixed base plate 4, and when the small-diameter shaft portion 6b rotates to the folding position as shown in FIG. It has reached the upper end of the escape hole 11. When the lock shaft 6 is released from being pressed at this position, the lock shaft 6 is slightly moved by the bias of the spring 8, and the shoulder between the large-diameter shaft portion 6a and the small-diameter shaft portion 6b forms a side wall plate portion of the fixed base plate 4.
