する必要があり、工数がかかるという問題がある。However, with the conventional device described above, when adhesive is injected into the hole, the adhesive flows down the slope of the magnet protection cover and accumulates in the space for the adhesive reservoir, but because this space is small, the inner circumferential surface of the magnet protection cover Because the adhesive flows into the adhesive, it is necessary to wipe it off, resulting in poor workability.Also, it is necessary to cut the iron fence to create a space for the adhesive reservoir, which increases man-hours. There is a problem that it takes.

ことを目的とする。In order to solve the above problems, the present invention forms an adhesive reservoir space between the bottom surface of the iron fence, the magnet attached to the inner circumference of the iron fence, and the magnet protection cover, and connects the inner circumference of the iron fence and the magnet protection cover. By providing an adhesive injection hole on the bottom of the iron fence between the two, the adhesive can be stored in the adhesive storage space, and the adhesive will not leak out of the adhesive injection hole. Since there is no need to wipe off the adhesive,
The purpose is to improve workability and to be able to manufacture with a simple structure.
以下本発明を図に示す実施例について説明する。 The present invention will be described below with reference to embodiments shown in the drawings.

内周面に環状の磁石保護カバー３が装着しである。In the first embodiment shown in FIG. 1, ``■'' is an iron fence made by drawing a magnetic plate such as an iron plate into a bowl shape. And this iron fence
A hole 1d and a positioning protrusion 1a are formed in the center of the bottom surface for mounting the shaft 4 that transmits engine rotation. Further, an inductor IC for generating an ignition signal is protruded from the outer periphery of the iron fence 1. A plurality of arc-shaped magnets 1 are arranged in a ring shape on the inner periphery of the iron fence 1, and an annular magnet protection cover 3 is attached to the inner periphery of the magnets 1.

One end of this magnet protection cover 3 (the open end side of the iron fence 1) is bent in the radial direction to match the end surface of the magnet 2, and then a first
A second flange portion 3b is formed at the other end, and the second flange portion 3a is shaped to follow the inner peripheral surface of the iron fence 1 for reinforcing the magnet protection cover 3 and ensuring a contact surface. Then, on the iron fence 11+111 of the magnet protection cover 3, place a punched out part (0.2 to 0.5 (ml)) at a position corresponding to the axial length of the magnet 2.

することができる。In addition, an adhesive reservoir space 5 is formed between the magnet 2, the bottom surface of the iron fence l, and the magnet protective cover 3, and one or several adhesive reservoirs are arranged at equal intervals on the bottom surface of the iron fence l corresponding to this space 5. A hole 1b for injecting the adhesive is formed. The hole 1b for injecting the adhesive can be formed at the same time when the iron fence 1 is drawn.
次に、上記構成において製造工程を説明する。Next, the manufacturing process for the above configuration will be explained.
磁石保護カバー３の外周面に、着磁されていない磁石２
を打ち出し部３Ｃで位置決め、配置した後に、鉄柵１に
磁石保護カバー３が挿入しである。A non-magnetized magnet 2 is placed on the outer peripheral surface of the magnet protection cover 3.
After positioning and arranging the magnets using the protruding parts 3C, the magnet protection cover 3 is inserted into the iron fence 1.

て接着剤を硬化させ、何ｉ石２を鉄柵１に固定する。Then, the first flange part 3b of the magnet protection cover 3 is fitted, and the second flange part 3a is driven in until it hits the bottom surface of the iron fence 1, so that the magnet protection cover 3 is press-fitted and fixed to the iron fence 1. At this time, the magnet 2 comes into contact with the outer peripheral surface of the magnet protection cover 3 due to friction when the magnet protection cover 3 is driven. Further, in order to check whether the magnet 2 is securely in contact with the outer peripheral surface of the magnet protection cover 3, a jig can be inserted through the hole 1b to check. Then, several glue bends 1f are provided at the open end of the iron fence 1, and the magnet protection cover 3 is attached to the iron fence 1.
It is possible to prevent the magnet from coming out or to prevent the magnet protection cover 3 from rotating. Thereafter, the adhesive is stored in the adhesive reservoir space 5 through the adhesive injection hole 1b, and heated to a certain temperature to lower the viscosity of the adhesive. Then, the adhesive passes between the magnet 2 and the iron fence 1, and between the magnet 2 and the magnet protection cover 3, and after penetrating the entire area, it is further heated to harden the adhesive, and the stone 2 is removed. Fix it to iron fence 1.

する。Here, when the adhesive is passed through the entire surface, the first flange portion 3b of the magnet protection cover 3 fits into the iron fence 1,
Since it is press-fitted and the contact surface with the inner circumferential surface of the iron fence 1 is made large, the adhesive will not leak from between the flange portion 3b and the iron fence 1. After fixing the magnet 2, the magnet 2 is magnetized using a magnetizer. After that, install the iron fence 1 using the hole 1.

Further, the iron fence 1 may be provided with a recess 1e and the play 1-7 with a projection 7a, and these recesses 1e and projections 7a may be engaged to fix the shaft 4 to the iron fence 1 with the pole I-10. Teeth for positioning the iron fence l relative to the shaft 4 are formed on the outer periphery of the shaft 4 and in the slot 4a of the plate 7, respectively. From the above, the shaft 4 can be fixed more reliably than in the first embodiment, sufficient strength can be obtained even if the iron fence l is made thinner, and the plate 7 can be attached easily even when changing the ignition timing etc. The position of the iron fence 1 relative to the shaft 4 can be changed simply by changing the position of the teeth formed on the shaft 4a for each plate and replacing the plate.

It is not necessary to form the protruding portion 3C for positioning the magnet 2.

、あまり問題はない。In FIGS. 1 to 3, the magnet protection cover 3
The magnet protection cover 3 was fixed by fitting and press-fitting one end of the open end of the iron fence l, but as shown in the fourth embodiment shown in FIG. Press-fit one end of the magnet protection cover 3 into the second flange portion 3a.
The magnet protection cover 3 may be fixed by tightening the protrusion 1e integrally provided on the bottom surface of the iron fence 1. Further, instead of the protrusion 1e, the magnet protection cover 3 may be fixed by repositioning, welding, or the like. Since one end of the magnet protection cover 3 is press-fitted, when the adhesive is infiltrated, it will not leak from between the iron fence 1 and one end of the magnet protection cover 3. Also, if one end of the magnet protection cover 3 and the iron fence 1 are not press-fitted and there is a slight gap, the adhesive will drip downward from this gap.
There is no adhesive on the inner circumferential surface of the magnet protection cover 3.
, not much of a problem.

工数もかからないという優れた効果がある。As described above, in the present invention, the iron fence, the magnet attached to the inner circumference of the iron fence, the magnet protection cover placed on the inner circumference of the magnet, and the bottom surface of the iron fence, the magnet, and the magnet protection cover. Since it is equipped with an adhesive reservoir space and an adhesive injection hole provided on the bottom of the iron fence between the inner peripheral surface of the iron fence and the magnet protection cover, adhesive can be stored in the adhesive reservoir space. Adhesive does not leak out of the adhesive injection hole, and there is no need to wipe off the adhesive, improving work efficiency and making it easier to process adhesive injection holes and iron fences. Since it can be formed simultaneously at the same time, it has an excellent effect of having a simple structure and requiring no man-hours.
