PROBLEM TO BE SOLVED: To provide an insulation wave guide tube that is inexpensive, is able to improve workability, and is able to obtain stable fastening force for a long time.SOLUTION: An insulation wave guide tube is composed of a plurality of wave guide tubes and adjacent wave guide tubes are fastened via an insulating member. The insulation wave guide tube has a substantially cylindrical support member inserted in a hole and formed from an insulation material, the hole being formed from a first through-hole provided in a first flange of one of adjacent wave guide tubes, a hole part provided in the insulating member, and a second through-hole provided in the second flange of the other of the adjacent wave guide tubes, these holes communicating with one another. The support member has: a projection part abutting on the first flange and projecting from the first through-hole; and a flange part abutting on the periphery of the opening part of the second through-hole in the second flange. A metal screw is inserted such that the screw head is located at the projection part of the support member, and the screw is fixed by a metal nut member so as to abut on the flange part. |
