At the time of wearing, the arm portion has a gap with the head due to the curved shape. For this reason, even if a spectacles user wears HMD, an arm part cannot contact a spectacles frame easily.
  • Patent Document 1 In order to allow the arm portion to reach from the rear side to the front side, in Patent Document 1, it is necessary to form the arm portion relatively long. A large torque is applied to the connecting portion between the arm portion and the wearing tool as the weight increases as the arm portion extends. When the holding torque for holding the arm portion by the connecting portion is increased, the force required to move the arm portion at the time of mounting increases. In Patent Document 1, there is a possibility that the position of the image display device is difficult to finely adjust. Further, the image display device and the arm portion vibrate with the connection portion as a fulcrum by a slight movement of the head when worn. The shaking width of the image display device increases according to the length of the arm portion. Therefore, in Patent Document 1, there is a possibility that an image displayed on the image display device is likely to be blurred.
