実例によりその内容について説明する。[Detailed description of the invention] This invention attempts to eliminate the use of adhesive for magnets, eliminate phase adjustment, and reduce the number of parts by fitting and fixing magnets into a synthetic resin case.0 Conventional In the past, motors were assembled by gluing the metal case and magnets together using adhesives, or by using parts for fixation. Therefore, it took a lot of man-hours for gluing and caused problems with the basic functionality of the motor. The present invention has been devised in view of these points, and its contents will be explained below with reference to illustrated examples.

１は合成樹脂製のケース体でＣ型の磁石２を嵌合固定す
べく嵌合固定機構３を形成しである。Reference numeral 1 denotes a case body made of synthetic resin, on which a fitting and fixing mechanism 3 is formed to fit and fix a C-shaped magnet 2.

この嵌合固定機構３は合成樹脂の弾力性を一部利用して
あり、構造的には外側壁面部４と磁石載置台部５より垂
直方向に突設せしめた押え柱部６と紋押え柱部６の頭部
に設けた傾斜面を有する爪部７とから形成しである。This fitting and fixing mechanism 3 partially utilizes the elasticity of synthetic resin, and is structurally comprised of a presser post 6 and a presser post that protrude perpendicularly from the outer wall surface 4 and the magnet mounting base 5. It is formed from a claw part 7 having an inclined surface provided on the head of the part 6.

而してＣ型の磁石２を第１図の如く嵌合固定機構３内に
嵌合することにより該磁石２は矢標Ａ方向、矢標Ｂ方向
、矢標Ｃ方向即ち半径方向、上方向、円周方向へずれ動
くことはない。By fitting the C-shaped magnet 2 into the fitting and fixing mechanism 3 as shown in FIG. , it does not shift in the circumferential direction.

８は刷子でケース体１上に取り付けてあり、その位置付
けは磁石２，２との相対関係により適宜勘案採択しであ
る。8 is attached to the case body 1 with a brush, and its position is determined as appropriate depending on the relative relationship with the magnets 2, 2.

９は磁石２の磁路を作るもので筒状の金属ケースより形
成してあり、切欠部１０を設けこの切欠部１０が外側壁
面部４をガイドとしてケース体１と金属ケース９とを嵌
合せしめることができる。Reference numeral 9 creates a magnetic path for the magnet 2, and is formed from a cylindrical metal case, and is provided with a notch 10, which allows the case body 1 and the metal case 9 to fit together using the outer wall surface 4 as a guide. You can force it.

又第３図の如き金属ケース９Ａを採用すればより一層安
価となる。Further, if a metal case 9A as shown in FIG. 3 is used, the cost will be even lower.

次に叙上の構成より成る本考案品の組立順序について説
明する。Next, an explanation will be given of the assembly order of the product of the present invention having the above configuration.

ケース体１の嵌合固定機構３に於ける押え柱部６を拡開
しＣ型の磁石２を滑り込ませることにより磁石２は押え
柱部材６の弾性力により嵌合固定機構３内に嵌合固定せ
しめられる。By expanding the presser post part 6 of the fitting and fixing mechanism 3 of the case body 1 and sliding the C-shaped magnet 2 in, the magnet 2 is fitted into the fitting and fixing mechanism 3 by the elastic force of the presser post member 6. Fixed.

然る時刷子８との関連において適性位置に位置付けされ
たこととなる。At that time, it has been positioned at an appropriate position in relation to the brush 8.

然る後、回転子（図示せず）を装備し、金属ケース９を
被ぶせればよい。After that, a rotor (not shown) may be installed and the metal case 9 may be covered.

叙上の如く本考案では刷子８を予めケース体１の適宜位
置に配設しておいて、Ｃ型磁石を嵌合固定機構３に嵌合
せしめるだけでよいので磁石と刷子との相関位置を正し
く最初から決めることが出来、モーターの最適特性を得
ることが出来る。As mentioned above, in the present invention, it is only necessary to arrange the brush 8 at an appropriate position on the case body 1 in advance and to fit the C-shaped magnet into the fitting and fixing mechanism 3. It can be determined correctly from the beginning and the optimum characteristics of the motor can be obtained.

又材質的弾力性を附与した嵌合固定機構３を、外側壁面
部４と押え柱部６と爪部７とにより構成しであるので、
Ｃ型磁石を半径方向、上方向、円周方向等の各方向へず
れ動くのを防止できる。In addition, since the fitting and fixing mechanism 3, which is endowed with material elasticity, is constituted by the outer wall surface portion 4, the holding column portion 6, and the claw portion 7,
It is possible to prevent the C-shaped magnet from shifting in various directions such as the radial direction, upward direction, and circumferential direction.

更に金属ケース９に切欠部１０を設け、ケース体１に外
側壁面４を設けであるのでこれをガイドとして金属ケー
ス９を容易に嵌合できる。Further, since the metal case 9 is provided with a notch 10 and the case body 1 is provided with an outer wall surface 4, the metal case 9 can be easily fitted using these as a guide.

等その実益する処大なるものがある。There are great benefits to this.
