Antenna mounting device for attaching a rod-shaped antenna to a vehicle

摘要

An apparatus for attaching a rod-shaped antenna to a vehicle comprises supporting plates and a hollow holding member (19) which is formed in a hollow truncated-conical shape, and which includes an opening portion and an elongated-hole formation portion having an elongated hole formed in the upper wall of the hollow holding member. The supporting plates (16, 17) have contact portions and center portions supported to allow supporting plates to rotate at journal support points. The journal support point of each of the supporting plates (16, 17) may be placed within the range of the thickness of the wall when the contact portions of each supporting plate are put into contact with the inner surface of the wall. The elongated-hole formation portion has inner and outer surfaces each of which is arcuated along a circle having a center at the journal support point when the opening portion of the hollow holding member is attached to the wall. <IMAGE>
