Claims

[Scope of utility model registration request]

Lifting parts installed vertically on the lower surface of both ends of the top plate are vertically movably fitted into legs installed below the lifting parts, and are formed of two strip-shaped plates, with the center of the lengthwise center A link whose parts are pivotally connected to each other is provided between the top plate and the leg, and the two upper ends of the link are attached to the bottom surface of the top plate in the depth direction of one or both of the ends. is slidably attached, and the two lower ends are slidably attached to the legs in the same way as the upper ends,
The opposing upper ends of both the left and right links are connected to each other by connecting rods, one of the connecting rods is inserted in the orthogonal direction, and a rotation introduction shaft rotatably fixed is provided in the depth direction of the top plate. The rotation introduction shaft has a handle for rotation at one end, and the other end is attached to the shaft by inserting a special nut fixed to a connecting rod on the other side different from the connecting rod through which the rotation introduction shaft is inserted. The special nut has a threaded part divided into a plurality of parts in the axial cut plane, which is housed in the main body, and the joint surface between the main body and the threaded part has a small diameter in the direction toward the handle of the rotation introduction shaft. 1. A height adjusting device for a top plate of a desk, etc., characterized in that the device is formed into a tapered conical surface, and has a threaded portion biased toward the tapered small diameter side by a spring.
