Abstract
A joint assembly provided to an end portion of antenna rod is placed between supporting portions of an antenna base. A click cylinder is then introduced into a hole of the supporting portion to engage recess and convex portions formed on a plate as an end surface of the click cylinder and an inner sursurface of the joint assembly, thereby generate click resistance. A coil spring is inserted into the click cylinder thereafter, then a bolt is introduced into the click cylinder through a washer. The bolt is screwed with a nut via a wave washer, a washer, and a spring washer.
Claims4
A pivottable connection configuration of a retractable roof mounted antenna having an antenna rod and an antenna base for rotatably supporting the antenna rod, comprising:
- a joint portion provided to one end portion of the antenna rod, said joint portion having a cylindrical member with a bottom and a rotation axis orthogonal to an axis of the antenna rod, said cylindrical member having a first and second surfaces perpendicular to the rotation axis, the first surface having one of recess and convex portions for generating click resistance, the second surface having a terminal surface electrically connected to the antenna rod;
- a pair of supporting portions comprising a first and second supporting portions formed in an upper portion of the antenna base so as to surface each other, the first supporting portion having a through hole, the second supporting portion having a terminal portion electrically connected to the terminal surface of the joint portion on an inner surface facing to the through hole;
- and
- a click cylinder having one of convex and recess portions to be engaged with said one of the recess and convex portions of the first surface of the cylindrical member.
