とするものである。[Detailed Description of the Invention] (Purpose of the Invention) The present invention relates to the structure of a case of a micromotor. A conventional structure will be explained with reference to FIG. 1 is the motor case and 2 is the tap.
This tap 2 is made by drilling a hole in the motor case 1 and processing a tap on the side of the hole.
Since it passes through the motor case 1, a packing 3 made of resin is provided to prevent dirt from entering the motor case and to prevent noise from leaking. Note that 4 is a stator magnet, and 5 is a bearing metal. The object of the present invention is to improve the productivity and economy of the conventional structure by creating a structure that does not require the packing 3.

且つ精密にできる。 In FIG. 2, reference numeral 1 denotes a motor case, which consists of a cylindrical portion 1a and a bottom portion 1b. At the center of the bottom portion 1b, there are provided a center hole 1c into which a bearing metal 5 that supports the rotating shaft of the motor is fitted and supported, and recesses 6 (generally a plurality of recesses) for mounting the motor on a fixed portion. The recess 6 has a cylindrical shape with a bottom, and the bottom 1d
is made to protrude inward of the motor case 1 during drawing processing (including press processing). Further, on the inner surface of the cylindrical portion of the recess 6, a tap screw 7 is cut into which a mounting screw (not shown) is screwed when the motor is mounted. The stator magnet of the motor is fitted and supported in the cylindrical part of the motor case 1, and since the concave part 6 is closed by the bottom part 1d, dust does not enter inside the motor, and the tip of the bottom part 1d is closed. Since the stator magnet 4 is positioned by , the assembly and adjustment of the motor can be made extremely simple and precise.
（考案の効果）
以上の通りであるから、本考案は次のような優
れた効果を奏するものである
(イ) 凹部６の底部が閉塞されているから、埃りが
内部に侵入することがない。(Effects of the invention) As described above, the present invention has the following excellent effects (a) Since the bottom of the recess 6 is closed, dust cannot enter inside. do not have.
(ロ) 凹部６の底部先端で固定子マグネツト４が位
置決めされているから、モータの組立て調整作
業が著しく簡単且つ精密にできる。(b) Since the stator magnet 4 is positioned at the bottom tip of the recess 6, the motor assembly and adjustment work can be done extremely easily and precisely.
(ハ) 凹部の形成を絞り加工（プレス加工を含む）
の際にその加工工程と同時にできるから、作業
能率が著しく向上する。(c) Drawing process (including press process) to form the concave part
This can be done at the same time as the machining process, significantly improving work efficiency.
