Claims

[Claims for Utility Model Registration] 1. A bottom parallel link mechanism consisting of upper and lower parallel links whose base ends are pivotally attached to the fixing brackets in the legal example, and whose base ends are pivoted to the fixing brackets on the lower surface of the object to be lifted and lowered. a top parallel link mechanism consisting of upper and lower parallel links, a common vertical intermediate link pivotally connected to the tips of the parallel links of the bottom parallel link mechanism and the tips of the parallel links of the top parallel link mechanism, and the top parallel link mechanism. is rotated in the vertical direction, and the angular displacement of the top parallel link mechanism with respect to the intermediate link caused by the rotational displacement of the top parallel link mechanism by this drive device is detected, and the angular displacement and quantitative and an angular displacement transmission mechanism that applies a displacement to the bottom parallel link mechanism that is equal and opposite to the angular displacement for the intermediate link. 2. The angular displacement transmission mechanism includes a pair of gears supported by the intermediate link in a mutually meshing state, a gear fixed to the tip of the bottom parallel link mechanism so as to mesh with one of these gears, and the pair of gears The elevating device according to claim 1, which is registered as a utility model and is constituted by a gear fixed to the tip of the top parallel link mechanism so as to mesh with the other gear.
