Abstract: A roof-mount antenna mounting structure includes a first threaded part, a second threaded part, a legged washer, a leg opening preventing part and a receiving part. The legged washer has a washer ring having a size smaller than the diameter of a mounting hole of a vehicle roof and a leg part extending from the washer ring and having a plurality of claws that can abut against the vehicle roof. The leg part has such elasticity that it closes once when the legged washer is inserted into the mounting hole of the vehicle roof from the washer ring side and recovers to substantially the original opening state after insertion. The leg opening preventing part has a horizontal part and a vertical part and prevents the leg part from opening at a predetermined angle or more when the claws abut against the vehicle roof.
