Summary: | PROBLEM TO BE SOLVED: To provide a structure of a portion for fixing an antenna element certainly fixed to provide high reliability by breaking, a pointed portion in each of right and left two ribs inside an arm, into a peripheral wall of the antenna element corresponding to each of the pointed portions. SOLUTION: In each of inner surfaces of right and left walls on a tube wall of the boom, the two ribs elongated in an axis-line direction of the boom are juxtaposed in such a manner as to vertically form a gap therebetween. Each of cross-sectional forms of the two ribs is formed in a chevron-shape. A diameter of a hole of the tube wall is formed larger than a gap between ridge lines of the right and left two ribs. Besides, the ridge line of the rib is cut out at a position where the hole of each tube wall is provided. Eight pointed portions in the right and left two ribs are allowed to be broken into the peripheral wall of an antenna element corresponding to each of the pointed portions. The antenna element is fixed to the boom with antenna's turning and axial motions blocked by the eight pointed portions. COPYRIGHT: (C)2010,JPO&INPIT |
