Title:
ONBOARD ANTENNA
Document Type and Number:
Japanese Patent JP3892288
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an onboard antenna in which a retractable antenna part 12, which is erected as a prescribed attitude from a base member 10 fixed to a vehicle, is tipped over under an external force, and when the force is released, it auto-restores to a prescribed attitude.
SOLUTION: A rod-like retractable antenna part 12, with a built-in antenna element 12b, where an oscillating shaft 14 penetrates its base end, is disposed on a base member 10 which is fixed to a vehicle, for free oscillation. The oscillating shaft 14 is loosely fitted with a coil spring 24. One end of the coil spring 24 is disposed to the retractable antenna part 12 while the other end is disposed to the base member 10. The elastic force around the oscillating shaft 14 of the coil spring 24 holds the retractable antenna part 12 in a prescribed attitude against the base member 10. Further, a click mechanism is provided which holds the retractable antenna part 12 in the prescribed attitude against the base member 10 by utilizing the elastic force around the oscillating 14 of the coil spring 24.
