ANTENNA DEVICE FOR VEHICLE

PROBLEM TO BE SOLVED: To provide an antenna device for a vehicle allowing formation of a proper communication area, even when a bar antenna is disposed in a door mirror. SOLUTION: In this antenna device, the bar antenna 13 is disposed in the door mirror 10 rotatably supported by a mirror bracket 9 provided integrally with a body part 7a of a door 7 of a driver's seat to rotate between a using position and a storing position, and a request signal is transmitted to the communication area set around the door 7 of the driver's seat through the bar antenna 13. In this case, when an antenna axis m is made parallel to a horizontal direction and the door mirror 10 is located at the using position and the storing position and between both of the positions, the bar antenna 13 is disposed so that a region held by pillars 2a and 2b may not be located on an axis of the antenna axis m.
