Abstract: PURPOSE:To facilitate and make an antenna adjustment job safe by providing a stopper supporting an antenna mount outer cylinder and an operation jig able to operate a pressing fixture through an external operation to the adjustment device. CONSTITUTION:An antenna is mounted by using a stopper 3, and the direction of the antenna is adjusted so as to obtain an optimum video image while an outer cylinder 2 is turned around a shaft with a rod member or the like in the releasing state that a pressing jig 9 is loosened, that is, an operation section 15b projected to the outside of the outer cylinder of an operation lever 15 almost in the horizontal state (state shown in chain lines). Since the pressing jig 9 does not depress the support in this state, the outer cylinder 2 is turned around the shaft on the stopper. When the optimum direction is decided, the outer cylinder 2 is fixed to the support 5 in the direction. The fixing is implemented by pushing down an engagement ring 2 provided to a lower end of an operation rod 20. Then the pressing jig 9 is pressed to the support 5 and the support 5 is fixed between the pressing jig 9 and the inner circumferential face of the outer cylinder 2.
