(Indicated by the arrow in FIG. 10). As a result, the falling motion of the leg 6 can be easily performed with one touch by pushing the operating body 26, and the operability can be improved. Also, when the tabletop 2 is transported or stored, the leg 6 may be lifted while the tabletop 2 is lifted while the leg 6 is lying below the face plate 4 in a lying state.
Since the device does not stand up, it can be handled easily. Further, when the standing leg 6 is to be erected, when the leg 6 is gripped and turned in the erecting direction (indicated by the dashed line in FIG. 10), the falling slope 30 and the falling slope 30 are rotated. When the locked state with the locking edge portion 38 is released, and the leg 6 is further erected to be in a substantially upright state (indicated by a one-dot chain line in FIG. 9), the erected side locking slope portion 32 and the erected side engaging member are engaged. The retaining edge 40 is locked, that is, locked, and the upright state is maintained. As a result, the standing state of the leg 6 can be firmly held, and the entire tabletop 2 can be made firm during use (see FIG. 8). In addition, the locking of the falling-side locking slope 30 and the rising-side locking slope 32 to the locking fixed body 36 can be performed even if the effect of slope tightening is reduced. The fixing holes 42-1a, 42-1b and 42-2a, 42-2b are formed in the fixing portions 42-1 and 42-2 on the back surface 4a of the 4 in parallel to the moving direction of the operating body 26, and the mounting screws are formed. 43-1a and 43-1b and 43-2a and 42-2b, the fixing fixture 36 is removed, moved to the crosspiece 10 side, and attached to the back surface 4a of the face plate 4 again (the 7 (indicated by an arrow in FIG. 7), the tightening of the leg 6 can be secured almost permanently, which is practically advantageous. Further, by using the locking fixing body 36 having a U-shaped cross section, the assembling workability can be greatly improved, and the handling can be facilitated and the manufacturing can be performed at low cost.
