An antenna device attached to a vehicle includes a base to which an antenna is fixed, a cover that is attached to the base, and a flexible pad that covers and supports an edge of the base, contacts an edge of the cover, and is located between the vehicle and the cover. A protrusion is provided on a surface of the pad on the cover side, and includes a body portion formed along the edge of the base, and a plurality of rib-like portions extending from the body portion to an edge of the pad.

Antenna device attached to vehicle

A vehicle pole antenna fixed to an antenna support base includes: a rod, a helical antenna element, a joint, and a mast cover. The rodhas flexibility and insulation property and has a concave portionat its base end surface. The helical antenna elementhas a coated wire wound around the rod. A winding density of the helical antenna elementadjacent to a bending start point of the rod is lower than that at the other portions. The jointhas a convex portionto be fitted to the concave portionformed at the base end surface of the rod. The jointis electrically connected with the helical antenna elementand connected to the antenna support base.

Vehicle pole antenna

The vehicle roof mount antenna to be detachably mounted on a vehicle roof is mainly constituted by an antenna cover, an antenna base, a boss, a pad, an annular rib, and an annular groove portion. The padhas a boss holethrough which the bosspenetrates and is disposed between the antenna baseand the vehicle roof R. The annular rib, which is made of an elastic material, is provided on the vehicle roof R side surface of the pad. When the vehicle roof mount antenna is fixed to the vehicle roof R, the annular ribis inclined from the boss holetoward a periphery of the pad. The annular groove portionis provided at a position where the pressing force of the annular ribagainst the vehicle roof R can be reduced.

Vehicle roof mount antenna

Disclosed is a type of antenna for vehicles that is protected by having a cap fitted-onto an antenna cover that covers an antenna element thereof, wherein coming-off of the cap is prevented from happening. The antenna for vehicles, which is comprised by having an antenna rod mounted onto an antenna base, is provided with: a conductive rod element that is formed within the antenna rod, and connected to the antenna base; a joint section that covers at least the side face of the rod element in the axis direction thereof, and that comprises an inner-side cylinder that is formed in the vicinity of an end section at the opposite side of the antenna base and further comprises a joint engaging section, and an outer-side cylinder that is formed at the outer side of the inner-side cylinder; and a rod cap that comprises a cop engaging section for engaging with the joint engaging section.

Antenna for vehicles

The vehicle roof antenna mounting assembly comprises a convex portion (), a bolt () and a leg washer (). The convex portion is inserted into a mounting hole (RH) of a vehicle roof panel (R) and has a edge portion () and a inner threaded hole (). The bolt has a screw screwed to the threaded hole and is tightened to the convex portion. The leg washer has a plate washer ring (), a leg portion () and a taper portion (). The leg portion is extendedly provided from the washer ring toward the mounting hole. The taper portion is provided on the leg portion as opposed to the edge portion and abutted on the edge portion to expand the tip portion toward an outside of the mounting hole.
