Abstract

The vehicle roof mount antenna to be detachably mounted on a vehicle roof is mainly constituted by an antenna cover 1, an antenna base 2, a boss 3, a pad 4, an annular rib 5, and an annular groove portion 6. The pad 4 has a boss hole 7 through which the boss 3 penetrates and is disposed between the antenna base 2 and the vehicle roof R. The annular rib 5, which is made of an elastic material, is provided on the vehicle roof R side surface of the pad 4. When the vehicle roof mount antenna is fixed to the vehicle roof R, the annular rib 5 is inclined from the boss hole 7 toward a periphery of the pad 4. The annular groove portion 6 is provided at a position where the pressing force of the annular rib 5 against the vehicle roof R can be reduced. Thus, even when the vehicle roof on which the roof mount antenna device is mounted has a small thickness, it is possible to prevent the vehicle roof from being deformed while ensuring waterproofness and dustproofness.

Description

[0001] related application [0001] This application is related to Japanese Patent Application No. 2008-178412 filed on July 8, 2008, and claims the priority of the Japanese Patent Application. technical field [0002] The present invention relates to a roof mount antenna detachably mounted on a roof of a vehicle, and more particularly to a roof mount antenna with improved water resistance and dust resistance. Background technique [0003] Roof mount antennas typically have pads on the surface that contacts the roof of the vehicle. The gasket has an annular rib (flange) made of elastic material to improve water and dust resistance. The raised mounting pressure brings the annular rib of the pad into press contact with the roof, thereby ensuring the waterproof and dust-proof properties of the roof-mounted antenna. [0004] For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-102031) discloses an antenna for automobiles. The antenna has a pad in whi...
