An external thread portion of an antenna holder (12), mounted on an antenna body (11), is connected to an internal thread portion of an antenna holder-receiving member (15) provided on an antenna guide (18), and in this connected condition, an antenna is passed through an antenna body passage hole (17) formed in a casing (13). Then, a fastening member (19) is mounted in a fitting portion (20), which is formed in the casing (13) so as to fix the antenna, and is disposed in the vicinity of the antenna body passage hole (17), thereby fixing the antenna. Therefore, the antenna can be mounted and fixed without using much labor and time.
