To perform earth connection of an antenna amplifier to a vehicle body stably, with no impact of discrepancy of thermal expansion coefficient due to vibration or temperature change during travel.SOLUTION: A hollow synthetic resin spoiler 16 is provided with an antenna element 18, a spoiler side mounting plate 38 to be mounted on a body side mounting plate 34 is provided with an opening 42 communicating with the internal space S of the spoiler 16, and then an antenna amplifier 20 is attached to the body side mounting plate 34 on the inside of the opening 42, so as to be electrically connected with the body side mounting plate 34. Earth connection of the antenna amplifier 20 to a vehicle body 12 can be carried out stably, with no impact of discrepancy of thermal expansion coefficient due to vibration or temperature change during travel, reception performance of the antenna amplifier 20 is kept well, and the quality of a radio wave signal, outputted from the antenna amplifier 20, is improved advantageously.SELECTED DRAWING: Figure 2

    【課題】走行中の振動や温度変化による熱膨張率の差異の影響を受けることなくアンテナアンプの車両ボディへの接地を安定して行なう。【解決手段】合成樹脂製の中空状のスポイラー16にアンテナ素子18を設けると共に、ボディ側取り付け板部34に取り付けられるスポイラー側取り付け板部38にスポイラー16の内部空間Sに連通する開口42を設け、アンテナアンプ20を開口42の内側でボディ側取り付け板部34に取着してボディ側取り付け板部34に電気的に接続するようにした。走行中の振動や、温度変化による熱膨張率の差異の影響を受けることなくアンテナアンプ20の車両ボディ12への接地を安定して行なえ、アンテナアンプ20の受信性能を良好に保ち、アンテナアンプ20から出力される電波信号の品質を良好なものとする上で有利となる。【選択図】図2
