    a supporting plate unit which has a center portion pivotally and rotatably supported on the antenna holding portion, and a contact portion to be put into contact with an inner surface of the inclined wall of the vehicle;

    a hollow holding member which has a bottom opening portion having an inclined surface corresponding to the inclined wall of the vehicle, and encloses the antenna holding portion projecting outwardly from the antenna holding hole when the contact portion of the supporting plate unit is put into contact with the inner surface of the wall of the vehicle, the hollow holding member having an upper wall in which an elongated hole for insertion of the upper end portion is formed, the elongated hole having a length defining a range for an angle at which the rod-shaped antenna is to be inclined to the wall of the vehicle;

    a fixing nut which is to be engaged with the male screw of the antenna holding portion, which is inserted through the elongated hole, and which is tightened to project the antenna holding portion further outwardly from the wall, and to put the contact portions of the supporting plate unit into pressure-contact with the inner surface of the wall,wherein;

    a journal support point to the supporting plate unit is permitted to be placed within a range of a thickness of the wall, when the contact portion of the supporting plate unit is put into pressure-contact with the inner surface of the wall; and
