ている請求項第１項記載の高さ調整装置。[Claims for Utility Model Registration] 1. An arm whose one end side is pivotally supported by a first shaft, whose other end side is pivotable in the vertical direction, and at which a receiving member for a placed object is pivotally supported at the other end side; a lifting means that urges the arm to rotate upward; a friction lock means that expands and contracts the rod following the vertical movement of the arm and locks the expansion and contraction of the rod by the frictional force of a spring; and this friction lock. A release means for releasing the frictional force of the means, and an inclination adjustment means for controlling the tilting of the receiving member with respect to the arm by the frictional force of a spring, which is provided on a second shaft that pivotally supports the receiving member on the arm. A height adjustment device characterized by: 2. The height adjusting device according to claim 1, further comprising a parallel moving means comprising a parallelogram link formed by two arms and a link arm provided parallel to the arms. 3 Parallel movement consisting of a fixed pulley fixed to the pivot point of the arm, a rotating pulley fixed to the second shaft, and an endless belt stretched between the fixed pulley and the rotating pulley. A height adjusting device according to claim 1, further comprising means.
