Since these coupling parts are configured to rotate and are provided with a fitting part for forming the support arm and a latching part for folding angle regulating fitting, the member is not fixed to the proximal arm or the movable arm when forming the support arm. The member and the arm on the side to which it is not fixed are fitted together and fixed. Further, after loosening or removing the tightening nut and pivoting the movable arm, the movable arm or the proximal arm is fitted into the latching portion and tightened to maintain the folded state at the set angle.

全に保管、移動がなし得る効果がある。"Effect of the invention" The support arm structure of the parabolic antenna of the present invention having the above-mentioned structure and operation has a proximal arm that fixes the support antenna forming member to the reflecting mirror, and a movable arm that pivots and is movable. The two are connected at the center of rotation of the arm, and a locking device having a fitting part during assembly and a latching part at a predetermined angle when folded is fixed to one of the supporting arm forming members at the connecting part. During both assembly and folding, the perfect fit ensures that the primary radiator remains fixed without wobbling in the rotating direction, and the primary radiator does not become misaligned with respect to the focal point of the reflector. It does not hit the reflecting mirror surface or rattle even when the mirror is used, and it can be packed very compactly, making it economical and safe to store and move.
