ていた。Conventionally, in this type of device, a spacer made of a non-magnetic material is inserted into one iron arm having a jig hole drilled in advance, and after applying adhesive to the upper surface of this spacer, a magnet is inserted, and this magnet After applying the adhesive and placing the spacer on the end of the iron arm, tighten the protrusion and heat it. A method was used in which the magnet and the iron arm were fixed with adhesive.

、回転子が不良品となってしまうという欠点がある。However, with the above-mentioned conventional method, the adhesive applied to the spacer is pressed from above by the magnet, so this adhesive is pushed out to the inner diameter side of the magnet and the iron arm side, so the adhesive is applied to the iron arm (the opening). If the jig hole is pushed out and adheres to the inside of the jig hole, and if it dries and sticks, the jig pin will not be able to fit into the jig hole, and the rotor will become a defective product. There are drawbacks.

。In order to solve the above-mentioned drawbacks, this invention provides a recess on the outer periphery of the spacer (between the magnet and the iron arm) to prevent the outer periphery of the opposing spacer from coming into direct contact with the inner diameter of the iron arm. (For this reason, even if the adhesive applied to the spacer is pushed out from the magnet in the direction of the gun, it will fall into the recess of the spacer, and the adhesive will not spill out to the jig hole that was made in the iron arm. The object of the present invention is to provide a rotor for a magnetic generator that can prevent clogging due to adhesive cutting.

以下本考案を図１こ示す実施例（こついて説明する。The present invention will be described below as an embodiment shown in FIG.

Each spacer 2, 4 and magnet 3 are fixed within the iron arm 1 by winding them inward.

３ａは磁石３の外周辺と鉄腕１の内周面との間１こ形成
した接着剤塗布用の空間である。3a is a space formed between the outer circumference of the magnet 3 and the inner circumferential surface of the iron arm 1 for applying an adhesive.

触面１ｃを接着固定させる。Then, insert one spacer 2 on the bottom side of the iron arm 1, apply adhesive on the upper surface 2af of this spacer 2, then insert one magnet 3 on the inner circumference side of the gun 1, and apply adhesive around the outside of this magnet 3. After applying adhesive to the space 3af and placing the spacer 4 thereon, the annular protrusion 1b is tightened and fixed, followed by heating.The applied adhesive flows out and makes contact between the magnet 3 and each spacer 2, 4. The surfaces 2a, 4a, and the contact surface 1c between the magnet 3 and the gun 1 are adhesively fixed.

つまることはなくなる。According to the above configuration, even if the adhesive applied to the upper surface 2a of the spacer 2 is pushed out from the magnet 31 toward the iron arm 1, this adhesive falls into the recess 2b of the spacer 2, and the adhesive is applied to the spacer 2 of the iron arm 1 and the magnet 3. The adhesive retainer 5 does not protrude to the outer peripheral portion of the joint with the jig hole 1a (this prevents the jig hole 1a from being clogged with adhesive).

。As described above, in the present invention 1, four parts are provided on the outer periphery of the spacer inserted between the magnet and the iron arm, and the jig hole (
Since the outer peripheries of the opposing spacers were rubbed so that they did not come into direct contact with the inside diameter of the gun, even if the adhesive applied to the spacer was pushed out from the magnet (in the direction of the iron arm), the pushed out adhesive would not flow into the recess of the spacer. This has an excellent effect in that the adhesive does not spill out into the jig hole where one iron arm was provided, and the jig hole is reliably prevented from being clogged by adhesive cutting.
