Claims

[Scope of utility model registration request]

An antenna body for ultra-high frequency waves, and a flexible insulated antenna in the shape of a cylinder with a bottom, which is molded separately from the antenna body for ultra-high frequency waves and is fitted and fixed to the antenna body for ultra-high waves by an integral means by screwing. The antenna main body for ultra-high frequency waves includes an antenna element for ultra-high frequency waves, a connector for connecting a transmitting/receiving set attached to an end face of a skirt section provided at the base end of the antenna element, and the skirt section. a male threaded portion provided on the outer peripheral surface of the antenna cover; and a male threaded portion provided on the inner peripheral surface of the antenna cover so as to be able to apply a rotational force to the ultra-high frequency antenna element in order to screw the male threaded portion into a female threaded portion provided on the inner peripheral surface of the antenna cover. The flexible insulated antenna cover includes a rotation operation section and a locking step provided at the base end of the antenna element, and the flexible insulated antenna cover is capable of being screwed into the male threaded section on an inner circumferential surface near the open end. When the coupling end surface of the connector comes to a position where the coupling end surface of the connector enters a predetermined distance inward from the open end surface of the cover due to the screw engagement between the female thread section and the male thread section, the locking step section 1. A very high frequency antenna device comprising: a stopper for inhibiting screw engagement, which is provided so as to abut against the screw portion and inhibit the screwing operation between the male threaded portion and the female threaded portion.
