A display apparatus is provided to control the high and low as supporting a TV or monitor. A spring unit(200) supports a display body(100) by using a spring device as adjusting the high and low thereof. The spring unit comprises a gas spring(210). The gas spring comprises a tube(211) and a rod(212). In the tube, predetermined gas is filled. The rod makes a round trip straight inside the tube. A friction member(300) generates the predetermined frictional force for the elastic force control. The friction member comprises a frictional guide(310) and a supporting member(320). In a hole, the frictional guide controls the elastic force of the gas spring as generating the frictional force together with the tube. The supporting member fixes the frictional guide, and supplements the supporting force of the spring unit for supporting the display body. |
