Abstract

To enable an antenna device to be easily mounted to a roof or the like, and to realize a highly reliable state or the antenna device after mounted. The invention relates to an antenna device comprising an antenna element, and a bottom cover and a top cover which cover the antenna element. The bottom cover includes a base projection to be inserted into an opening formed in a mounting part, a washer having an elastic force being fitted over this base projection, and the washer comes into contact with an inner face of the mounting part thereby enabling the antenna device to be mounted and fixed. The washer is inserted into the opening in the mounting part in a state fitted over the base projection, and recovered to its original shape by the elastic force after the insertion, thereby to be brought into contact with the inner face of the mounting part.

Dependent claims

An antenna device attached on an outer face of a plate member having a through hole connecting the outer face and an inner face of the plate member, the electric device comprising:

an antenna element;
a cover, defining a space for covering the antenna element;
a tubular projection, extended from the cover member so as to communicate with the space, the projection inserted into the through hole from the outside to the inside of the plate member in a first direction;
and
a washer, comprising:
a semiannular body, elastically fitted on an outer periphery of the projection;
and
an elastic piece, elastically deformable in a second direction which is perpendicular to the first direction to allow the washer to pass through the through hole from the outside to the inside of the plate member together with projection, the elastic piece being brought into contact with the inner face when the washer is placed at the inside of the plate member.
