The present invention provides an antenna device capable of retaining by a simple structure an antenna base end portion 12 pivotably and, moreover, in a predetermined posture on an antenna base member 10. The antenna base member 10 is provided therein coaxially with a cylindrical member 10d a part of a circumferential wall of which is cut off. The cylindrical member 10d is provided therein with a substantially annular elastic member 16, which has an engagement projection 16a extending outward from the cutoff portion in the radial direction and capable of being elastically displaced in the radial direction, in such a manner that the elastic member is not relatively turned. The antenna base end portion 12 is provided with an engagement recess 12a engaged with an outer circumference of the cylindrical member 10d, and the engagement projection 16a is elastically engaged with an inner circumferential surface of the engagement recess 12a. The engagement recess 12a is provided in an inner circumferential surface thereof with retaining recesses 12b, 12c with which the engagement projection 16a is elastically engaged with an antenna in predetermined postures substantially horizontal and of a predetermined angle of inclination. The engagement recess 12a is fitted around an outer circumference of the cylindrical member 10d, and the antenna base end portion 12 is provided pivotably on the antenna base member 10.
An antenna device in which an antenna base end portion is provided pivotably with respect to an antenna base member with an antenna retained in a predetermined posture, characterized in that one of the antenna base member and antenna base end portion is provided with an elastic member having an engagement portion capable of being elastically displaced in the radial direction with respect to an axis of a pivotal movement thereof so that the elastic member is not relatively turned, the other of the antenna base member and antenna base end portion being provided with a slide engagement section with which the elastic member elastically deformed by a turning movement of the antenna is slidingly engaged, the slide engagement section being provided with a retaining part with which the mentioned engagement section is engaged by the elastic force of the elastic member with the antenna in a predetermined posture.
An antenna device in which an antenna base end portion is provided pivotably with respect to an antenna base member with an antenna retained in a predetermined posture, characterized in that the antenna base member is provided with an elastic member having an engagement projection which extends radially with respect to an axis of a pivotal movement of the antenna, and which can be elastically deformed in the radial direction, in such a manner that the elastic member is not turned relatively, the antenna base end portion being provided with a slide engagement section with which the engagement projection elastically deformed by a turning movement of the antenna is slidingly engaged, the slide engagement section being allowable to be provided with a retaining recess with which the engagement projection is engaged by an elastic force thereof with the antenna in a predetermined posture.
