The purpose of the present invention is to enable a secure attachment of an antenna element and to facilitate adjustment of the antenna element characteristics. Rearward of a spoiler are formed a plurality of lateral grooves extending in a left-right direction of a vehicle, and a plurality of vertical grooves extending in a front-rear direction of the vehicle. The plurality of lateral grooves and the plurality of vertical grooves form latticed grooves as grooves in the shape of a lattice for installing an antenna element. The antenna element is formed by a conductive wire. One end of the antenna element is connected to an amplifier, and the other end is opened. The antenna element extends from the amplifier via a power feeding groove and the right-end one of the vertical grooves to the rear end of the groove, from which the antenna element is fitted in a route along the most rearward one of the lateral grooves to the vicinity of the left-end one of the vertical grooves, thus being securely attached to the spoiler.

Vehicle attached component, and on-board antenna

The antenna device is disposed inside a vehicle exterior accessory such as a spoiler which is mounted on the exterior of the vehicle body. An amplifier substrate is fixed to a bracket, amplifies wave signals received from an antenna element, and outputs the amplified signals. A GND bolt fixes the bracket to the vehicle body and electrically connects between the bracket and the vehicle body. An amplifier cover is fixed to the bracket to cover the amplifier substrate. An elastic member is provided covering the outer periphery of the amplifier cover between the amplifier cover and the vehicle body. The elastic member is compressed as the amplifier cover is pressed against the vehicle body.

Antenna device

Disclosed is a fixture to fix a vehicle component which comprises a metallic bolt to fix the vehicle component having a threaded portion to be threaded into a nut to fasten the vehicle component to the support member; a metallic bracket having a through-hole into which the threaded portion is inserted, the bracket holding the vehicle component between the bracket and the support member; and a metallic washer into which the threaded portion is inserted, the washer comprising a washer portion which contacts a peripheral edge of the fixture hole of the support member on the same side as the vehicle component and a locking portion which is provided integrally with the washer portion to be locked with and thus integrated with the bracket. According to the above constitution, the loosening of the nut can be prevented to stably maintain the earth performance of the vehicle body.
