FIG. 1 shows a conventional anode structure. A plurality of vanes 2 are provided radially from the inner wall of the anode cylinder 1 in the direction of the central axis, forming an anode body 3. The anode body 3 is known to have a structure in which the anode cylinder 1 and the vane 2 are integrally molded by press working, and a structure in which each part is formed separately and these are integrated by brazing or the like. There is. Vane grooves 2a are formed concentrically on the top and bottom of the vane 2.
An inner strap 4 and an outer strap 5 are fixed to the vane groove 2a so as to connect every other vane 2 to the vane groove 2a. Further, an antenna 6 is fixed to any one vane 2.
ところで、アンテナ６はベイン２に次のように

Grooves 2b and 6a are formed in the antenna 6 and the antenna 6, respectively, and as shown in FIG.
Insert the antenna insertion portion 6b in the upper part of the groove 6a into the vane 2.
The antenna 6 is attached to the vane 2 by inserting it into the groove 2b of the vane 2 and combining the grooves 2b and 6a with each other.

る。 To prevent this, conventionally, the antenna 6 of the vane 2
The antenna 6 is caulked and fixed by pressing the vicinity portion 2c (see FIG. 1) into a wedge shape. However, this method is extremely delicate because it causes problems in that the vane 2 is deformed in an attempt to obtain sufficient fixing strength, resulting in a decrease in oscillation efficiency and deterioration of oscillation stability. It has the disadvantage of requiring crimping adjustment.

An embodiment of the present invention will be described below with reference to FIGS. 4, 5, and 6. FIG. 4 is a perspective view of essential parts of the vane and antenna, FIG. 5 is a vertical sectional view of the antenna, and FIG. 6 is a sectional view taken along line A--A in FIG. 5.
A groove 12a is formed in the vane 12 as in the conventional case. The antenna 16 is formed with a groove 16a that is inserted into and combined with the groove 12a of the vane 12, and an insertion portion 16b that is inserted and fitted into the groove 12a is formed above the groove 16a. Step portions 16c, 16c that abut against the side surfaces of the vane 12 are formed on both sides of the vane 16b.

ン１２に挿入し易くなると共に、挿入するほどに
隙間が小さくなつて自ら固定されてしまう。 Therefore, the antenna 16 is placed in the groove 12a of the vane 12.
When the grooves 16a are inserted and assembled together, the insertion portion 16b is inserted and fitted into the groove 12a, and the stepped portions 16c,
16c comes into contact with the side surface of the vane 12, so the stepped portions 16c, 16c act as a stopper for the vane 12, and the antenna 16 is restrained from being independent and tilting in the width direction. Here, the groove 16a of the antenna 16
By making the lower end width H 1 of the antenna 16 slightly larger than the thickness of the vane 12 and the upper end width H 2 between the stepped portions 16c and 16c approximately the thickness of the vane 12, the antenna 16 becomes easier to insert into the vane 12, and the more it is inserted, the more the antenna 16 is inserted. The gap becomes smaller and becomes fixed by itself.

得られる。 In this way, the stepped portions 16c, 16 of the antenna 16
c acts as a stopper and clamps the vane 12 by the stepped portions 16c, 16c, so that the antenna 16 becomes independent. Therefore, although there is no need to caulk the vane 12 or the antenna 16, it is necessary to further increase the self-supporting accuracy of the antenna 16, or to prevent vibrations caused by transportation after the antenna is installed and before brazing, or to prevent the antenna 16 from coming off due to handling. Therefore, the vane 12 or the antenna 16 may be slightly caulked near the fitting portion thereof. In this case as well, sufficient self-supporting accuracy can be obtained with a slight caulking.

同様の効果が得られる。 FIG. 7 shows a second embodiment of the invention. In the embodiment described above, the insertion portion 16b was formed by forming a recess on both sides of the antenna 16, but in this embodiment, only one side of the antenna 16 is formed into a recess. Even if formed in this way, the same effects as in the embodiment described above can be obtained.

According to the present invention, the stepped portion of the antenna acts as a stopper and the vane is held between the stepped portions, so that the following effects can be obtained. The antenna position accuracy is high and the characteristics are stable. Furthermore, since strong caulking of the vane is not required, there is no deterioration of characteristics and the workability of assembly is extremely good. In addition, since the antenna can stand on its own, there is no need for a jig to hold the antenna, which eliminates the need for maintenance of the jig, and the brazing work is easy.Moreover, the heat capacity is small, and the energy cost of brazing is also low. .
