PROBLEM TO BE SOLVED: To direct an antenna opening to a target with simple constitution and to turn it by providing a mechanism turning an antenna in a state where it is supported almost in an fixed position. SOLUTION: The fixed pin of a sliding piece 15 is removed from a bracket 6 and the sliding piece 15 is removed from a bracket 5. An antenna 11 is freely slid and it is slid in a right direction along a rail 4. The sliding frame 18A of the antenna 11 is supported by the rotor of the bracket 5 on a right side. The fixed pin is inserted into a through hole and a through hole at the center of the rail 4 and the sliding piece 15 is fixed to the rail 4 at the center of the rail 4. The antenna 11 is turned in a left direction by 90 degrees with a turn pin as a center. Thus, a sliding frame 18B is supported by the rotor of the bracket 5 on the left side. Then, the antenna 11 is slid to a place where the sliding piece 15 arrives at the bracket 5 on the right side of the rail 4. Then, the fixed pin is inserted into the two through holes in the sliding piece 15 on the right side of the rail 4 and the sliding piece 15 is fixed to the bracket 5.
