LAUNCHER SUPPORTING DEVICE

PROBLEM TO BE SOLVED: To provide a launcher supporting device that can be operated lightly to a large elevation angle. SOLUTION: A launcher holder 2 is fixed on a car body and a revolving structure 5 is attached to the holder 2 in a state where the structure 5 can revolve around the center axis of the holder 2. A revolving mechanism 7 is installed to the revolving structure 5 so that a launcher 36 may be revolved in the horizontal direction. Then links 16 and 17 which are made longer on their front sides than their rear sides are rotatably attached to the left and right side sections of the structure 5 with spaces on their front sides and rear sides. In addition, quadric link mechanisms 14 and 15 are constituted of the links 16 and 17, a base 20 by rotatably attaching the base 2 to the links 16 and 17 astride the front and rear sides of the links 16 and 17, and a driving mechanism 22 which moves the base 20 upward, downward, forward, and backward by deformably driving a link shape formed of the link mechanisms 14 and 15 is provided so as to adjust the upward and downward angles of the launcher 36.
