PURPOSE: To attain the storage in which the limit of the width and height of a car are kept and a space for an antenna driving section and a mount section is ensured, by providing a hinge turned toward two directions orthogonal to the center of a part of a car mount parabola antenna in excess of the car width.

CONSTITUTION: A part 2 of a parabola antenna in excess of the limit of car width is supported with a hinge 3 having orthogonal rotating shafts and a rotating center shaft 4. In case of the storage, the part 2 in stretched state is opened to the outer side by taking the hinge as a center. Then, the part 2 is rotated for 180° by taking the shaft 4 as a center. Further, the part 2 is stored by rotating it to the inside with the hinge 3 as the center. Thus, the part in excess of the car width can be stored suitably without increasing the height of car while ensuring a space for the antenna driving section and the mount section.
