Abstract
A door mirror device includes an antenna and a metal frame for attaching parts. The antenna is capable of at least one of receiving radio transmissions from the outside of a vehicle cabin or transmitting radio transmissions to the outside of the vehicle cabin. The antenna includes a plate and a case that are electrically continuous with a matching-use base plate. The plate and the case of the antenna are fixed to the frame by a tapping screw. The antenna is grounded to the frame as a result of the plate becoming electrically continuous with the frame via the tapping screw.
Claims18
A vehicular door mirror device comprising:
- an antenna that is disposed inside a mirror enclosure disposed such that the mirror enclosure protrudes outward from a door of a vehicle, with the antenna being capable of at least one of receiving radio transmissions from the outside of a vehicle cabin or transmitting radio transmissions to the outside of the vehicle cabin;
- and
- a metal frame for attaching parts disposed inside the mirror enclosure, supporting the antenna with a fixing member, and serving as the ground of the antenna.
A vehicular door mirror device comprising:
- an antenna that includes
- a case that is electrically insulated and houses a matching-use base plate that adjusts at least one of the receiving efficiency or the transmitting efficiency of radio transmissions and
- a metal plate that is electrically continuous with the matching-use base plate and is exposed to the outside of the case,
- with the antenna being disposed inside a mirror enclosure that is disposed such that the mirror enclosure protrudes outward from a door of a vehicle and being capable of at least one of receiving radio transmissions from the outside of a vehicle cabin or transmitting radio transmissions to the outside of the vehicle cabin;
- a metal frame for attaching parts that is disposed inside the mirror enclosure and is electrically insulated as a result of an antirust treatment being administered to its surface;
- and
- a fixing member that fixes the antenna to the frame as a result of the fixing member being inserted into the plate and the case and is electrically continuous with the antenna and the frame, with the frame serving as the ground of the antenna.
