つた。(Problems to be Solved by the Invention) By the way, the above-described method of fixing via an adhesive is such that, for example, as shown in FIG. After fitting the parts together and placing the end face of one permanent magnet 2B on the plane of the fixing member 7, apply adhesive 6 to the end face of the other permanent magnet 2A and leave it as it is. As shown in Figure 3, a reed switch 3, permanent magnets 2A and 2B, and a temperature-sensitive magnetic body 1
The adhesive 6 infiltrates into the gap between the reed switch 3 and the permanent magnet 2, and then hardens.
A, 2B and the temperature-sensitive magnetic body 1 were fixed together.

供給しなければならないという手数を要する。 However, in the case of a small temperature-sensitive reed switch, the outer diameters of the permanent magnets 2A, 2B and the temperature-sensitive magnetic body 1 are correspondingly small, so if a relatively large amount of adhesive is supplied onto the end faces of the permanent magnets, However, the adhesive may leak onto the outer circumferential portion of the permanent magnet, resulting in inconveniences such as dimensional deviations or the need for rework. Furthermore, if a small amount of adhesive is supplied onto the end face of the permanent magnet, the adhesive must be supplied multiple times, which is a hassle.

着剤用凹部となる。 FIG. 4 is a perspective view showing an embodiment of the structure of the reed switch of the present invention, and FIG. 5b is a sectional view showing an embodiment of the structure of the present invention. (cylindrical) temperature-sensitive magnetic body 1
It is the same as the conventional structure in that it has a structure in which ring-shaped permanent magnets 12A and 12B are placed on both sides of the magnet 1, and the reed switch 13 is inserted into the hole 14 formed thereby. , a recess 15A is formed on the inner periphery of the outer end surface of one permanent magnet 12A disposed on both sides (the side facing the inserted reed switch 13), and the recess 15A is formed on the inner periphery of the outer end surface of the other permanent magnet 12B. 1
This structure differs from the conventional structure in that a recess 15B is formed symmetrically to 5A. In addition, in the figure, 1
3a and 13b are leads protruding from both sides of the reed switch 13 in the axial direction. Each of the recesses serves as an adhesive recess.

If you pour it in and leave it as it is, the 5th
As shown in FIG. b, the adhesive 16 penetrates into the gaps between the reed switch 13, the permanent magnets 12A, 12B, and the temperature-sensitive magnetic body 11, and then the adhesive 16 hardens and the reed switch 13, the permanent magnets 12A, 12A, 1
The thermosensitive magnetic material 10 as a product is assembled by fixing the thermosensitive magnetic material 2B and the thermosensitive magnetic material 11 and taking it out from the mounting groove 17a.

Ｂに流し込むために充分な量の接着剤の供給がで
きる。 As described above, since the adhesive 16 is poured into the recess 15A or 15B formed in the inner peripheral part of the end face of the permanent magnet 12A, it is possible to prevent the supplied adhesive 16 from leaking to the outer peripheral part of the permanent magnet etc. The adhesive 16 can penetrate into the gaps between the reed switch 13, the permanent magnets 12A, 12B, and the temperature-sensitive magnetic body 11 without waste. Also, the recess 15A or 15
A sufficient amount of adhesive can be supplied to pour into B.

う手間がなくなる。 In addition, if the recesses for adhesive are provided symmetrically in a pair of permanent magnets as in the above example, either recess can be used as a receiver for adhesive, so make sure to check the vertical direction each time when assembling. There is no need to perform positioning when pouring the agent.
更に、２つの永久磁石に同一形状の凹部を設け
るから永久磁石の断面積を同一とすることがで
き、凹部を設けることによつて特性に悪影響をも
たらすという不都合がない。 Furthermore, since the two permanent magnets are provided with recesses of the same shape, the cross-sectional areas of the permanent magnets can be made the same, and there is no problem that the provision of the recesses would adversely affect the characteristics.
そして、第５図ａに示したように固定部１７に

ので固定部１７に迄接着剤が洩れてしまうという
ような不都合がなくなる。 When the temperature-sensitive reed switch is set up on the fixed part 17 as shown in FIG. 5a and the adhesive is poured in, even if the adhesive flows downward as shown in FIG. Due to the presence of the recessed portion 15B located at the recessed portion 15B, the adhesive stops at the end of the recessed portion 15B, thereby eliminating the inconvenience of the adhesive leaking to the fixing portion 17.

容易にできる。 It goes without saying that the present invention is not limited to the above-described embodiments, and can be implemented with appropriate modifications within the scope of the gist of the present invention. For example, the 6th
As shown in the figure, recesses 15A, 15a, 15B, and 15b may be provided in the inner circumferential surfaces of the permanent magnets 12A and 12B at the end portions and adjacent portions of the temperature-sensitive magnetic body 11, respectively. According to this, the recesses 15A, 1 at both ends
5B can of course be used as a receiving part when pouring adhesive in the same way as described above, and since the adhesive that permeates into the recesses 15a and 15b formed adjacent to the temperature-sensitive magnetic body 11 accumulates, it is possible to use the reed switch 13 and the permanent magnet 1.
2A, 12B and the temperature-sensitive magnetic body 11 can be easily adhesively fixed.
尚、上記実施例はリング状の永久磁石を対象に
したが、角形であつてもよいし、楕円状等であつ
てもよい。 Although the above embodiment deals with a ring-shaped permanent magnet, it may be rectangular, elliptical, or the like.
