The thread 114 is formed in the opposing contact surface of the fastener 110, so that the vertical height of the opening 111 can be adjusted as needed.

A c-shaped rotating member 120 is installed on the protrusion 113 so that it can rotate in place, and a pair of first horizontal members 130 are connected in parallel to each other. The second horizontal member 150 is horizontally connected to the end of the first horizontal member 130 through the auxiliary tool 140. The second horizontal member 150 is supported by the assisting tool 140 to rotate in place. At the end of the second horizontal member 150, a support plate 160 is bent in a predetermined shape to allow the arm of the computer user to be placed thereon. One side of the first horizontal member 130 is provided with a fastening means 170 for fixing the two first horizontal members 130 to each other to adjust the height of the support plate 160.

That is, in the state where the arm support 100 shown in FIG. 1 is fixed to the desk using the fixture 110, a worker using a mouse or the like may work with the arm on the support plate 160. When the worker moves the arm for the mouse operation while the arm is placed on the support plate 160, the first horizontal member 130 and the second horizontal member 150 are rotated according to the position of the arm 120, respectively. The position is adjusted while being rotated about the assisting tool 140. That is, since the support plate 160 supports the arm of the worker, the worker can work comfortably.

However, the conventional arm support as shown in Figure 1 has a problem that the work is hindered if you want to do other work in addition to computer work because it can not be folded downward in the state installed on the desk. Accordingly, in some cases, the arm supports should be dismantled and reassembled when necessary.

The purpose of the present invention is to support the operator's arm when working on a computer, so that the worker can work for a long time in a comfortable posture, and when not in use, it can be folded downward so as not to disturb other work. To provide an arm support that can be.
