1. A vehicle antenna attachment to be installed and fixed with a vehicle roof panel nipped from vehicle compartment side by inserting part thereof into a mounting hole formed in the vehicle roof panel from external side of the vehicle, comprising:
- an antenna base disposed on external side of the vehicle with respect to the vehicle roof panel;
a protruding portion which is formed on the face on the side of the vehicle roof panel of the antenna base and to be inserted into the mounting hole while tapered faces expanded from the tip end side thereof to the proximal end side and a first threaded portion are formed on at least part of an outer peripheral portion thereof;
a tightening member having a second threaded portion which fastens to the first threaded portion and to be tightened to the protruding portion; and
a legged washer comprised of a sheet-like washer ring through which the tightening member passes, a first leg portion which is extended from this washer ring toward the mounting hole and whose tip ends are formed to be larger than the internal diameter of the mounting hole and has an elasticity, and a second leg portion which is extended from the washer ring toward the mounting hole and whose part of the inside face makes contact with the tapered face as the washer ring approaches the mounting hole when the tightening member is tightened so that the tip ends are expanded outward of the mounting hole.

Abstract
Comprised of an antenna base in which a protruding portion is formed on a bottom face and tapered faces are formed on shoulder portions of the protruding portion, a legged washer in which leg portions whose tip ends have an external diameter larger than the internal diameter of a mounting hole and which has an elasticity and leg portions, which are bent into a crank-like section so that the diameter of the tip ends is increased and in which the inside face of the crank portion makes contact with the tapered faces when the axial length of the bolt is decreased with respect to the antenna base by tightening the bolt so that the tip ends are expanded, are formed integrally with the ring portion, and a bolt which is fastened to the protruding portion of the antenna base through the legged washer.
