With the object of obtaining a reliable grounding of the antenna, even if the panel of the vehicle is deformed or the elasticity of the base pad or O-ring weakens, a washer portion 21 is integrally secured to a nut portion 20 via a wave washer 22. This securing is performed by mounting a joint portion 23 in washer portion 21, and by mating protuberances 23e of second protruding pieces 23d of joint portion 23 with a ring-shaped groove portion 20b that is formed inside a first through-hole 20a of nut portion 20. Even if the vehicle panel the antenna is mounted, and so forth, is deformed, or the stress on the antenna-mounting nut 6 weakens, this change is absorbed by wave washer 22, and thus a marked reduction in the press-contacting force of the antenna-mounting nut 6 does not occur, and the grounding of same is made reliable. <IMAGE> |
