Claims

[Scope of utility model registration request]

Lifting parts installed vertically on the lower surface of both ends of the top plate are fitted in vertically movable parts into legs installed below the lifting parts, and a rotation introduction shaft with a rotating handle extends to the depth of the bottom surface of the top plate. A rotation transmission shaft is provided in the direction, intersects with the rotation introduction axis and can transmit rotation toward both ends of the top plate, and is connected to both ends of the rotation transmission shaft on the side plate side of the desk, and A height adjusting screw shaft set in the vertical direction within the lifting section is rotatably supported at its upper end on the lower surface of the top plate, and its lower end is attached to the leg section via a special nut, The special nut has a threaded part divided into a plurality of parts in the axial direction cut plane, and is internally installed in the main body.
1. A height adjusting device for a top plate of a desk, etc., characterized in that a joint surface between a main body and a threaded portion is formed into a tapered conical surface with a smaller diameter on the downward side.
