<p>PURPOSE: To install a loop antenna at a proper position by providing a notch a metallic plate along a straight line passing through a center of a loop antenna in the length in excess of an outer diameter of the loop antenna so as to fix the loop antenna. CONSTITUTION: A transmission reception antenna 21 is mounted to a metallic plate 7 at a loop antenna mount position with an anchor bolt 8. A notch 9 is provided to the metallic plate 7 in a length in excess of an outer shape of the antenna 21 along a diameter of a loop of the transmission reception antenna 21. Then the outside of the loop antenna is solidified by a synthetic resin block 21a of a rectangular shape and four holes 21b to which the anchor bolt 8 is inserted are provided to a resin block 21a at the inside of the loop antenna main body 21c. The four holes 7a are made to the metallic plate 7 according to them. In order to cover the notches 9, the insulation coating tape 10 made of a synthetic resin in the same color of that of the surface of the metallic plate 7 is coated with a width larger than the width of the notch 9.</p> |
