たものである。 As shown in FIG. 1, the conventional flat motor 1 attracts a bracket 4 by the magnetic force of a permanent magnet 3 that is in close contact with a cover 2, and has a flat disk-shaped armature in a housing 5 constituted by the cover 2 and the bracket 4. The armature 6 is rotatably provided, and the armature 6 is rotated by passing current through a brush 7 that contacts the armature 6.

る。 The housing 5 of this motor 1, especially the cover 2, is equipped with a permanent magnet 3 and a brush holding part 8 on its inner peripheral surface. A sheet of plate is pressed or die cast molded. In other words, this cover 2 is made up of a single piece in any case, and when this motor is installed in a car cooler or the like, vibrations caused by internal vibrations generated in the brush 7, etc. or friction between the armature and the brushes are significant, and the cover 2 is made up of a single piece. 2
It is transmitted from the motor to various places.
Particularly in this flat motor, the gap between the armature and the permanent magnet is extremely important, and if the gap is too wide, the performance of the motor will be reduced. Therefore, it is necessary to prevent the above-mentioned vibrations as much as possible, so recently, when the brush holding part 8 is attached to the cover 2 as shown in FIG. 2, it is done through an elastic body 9.
しかしこの弾性体9を設けても単にブラシ保持
部8とカバー2との間の振動伝達を阻止するのみ
であり、前述した広範囲に伝幡する振動を阻止す

待できなかつた。 However, even if this elastic body 9 is provided, it only prevents the transmission of vibration between the brush holding part 8 and the cover 2, and cannot prevent the vibration that spreads over a wide range as described above. I could only expect such an effect.
そこで、本考案は、上述の欠陥に鑑みてなされ

徴とするものである。 In order to achieve the above-mentioned object, the present invention has a housing consisting of a cover having a permanent magnet on its inner circumferential surface and a bracket that is attracted to the cover by the magnetic force of the permanent magnet. In a flat motor, a flat motor is provided with rotatable flat disc-shaped armatures arranged opposite to each other with a gap, and a brush holder is attached to the cover, the tip of which contacts the armature and holds a brush that supplies power. The cover is composed of a circular dish-shaped bottom part that does not have a center part and to which the brush holding part is attached, and a donut-shaped outer edge part provided separately from the bottom part at the outer peripheral end of the bottom part. , the outer peripheral end of the bottom part and the inner peripheral end of the outer edge part are connected via an elastic member, and the outer peripheral end of the bottom part and the inner peripheral end of the outer edge part extend to a position where they overlap. It is characterized by the fact that it has been forced.
以下、本考案に係るハウジング構造の一実施例
を図面について説明する。 Hereinafter, an embodiment of the housing structure according to the present invention will be described with reference to the drawings.
第3図は、本考案に係るフラツトモータのハウ

ある。 FIG. 3 is a vertical sectional view showing the main parts of the housing structure of the flat motor according to the present invention, and is a vertical sectional view showing the main parts of the housing structure of the flat motor according to the present invention.
Components that are the same as those shown in FIG. 2 are designated by the same reference numerals.

者を弾性部材15により連結したものである。 The housing 11 of this flat motor, particularly the cover 12, has a generally circular dish-shaped bottom part 13 and a donut-shaped outer edge part 14, which are separately constructed and connected by an elastic member 15.

ー12を構成したものである。 That is, the bottom surface 13 of this cover 12 has a hole 16 for attaching a brush and is formed so that its outer peripheral edge rises at an angle, while the outer edge 14 forms a donut-shaped disk. A recess is formed inward in the radial direction, into which the permanent magnet 3 is fitted.
The cover 12 is constructed by fitting it into a groove pre-drilled in the groove.

4aにビスを挿通せしめてもよい。 However, if the elastic member 15 is simply inserted, there is a risk that the cover will lack rigidity, so the elastic member 15 is attached with the ends 13a and 14a slightly protruding so that they overlap. By forming the cover in this way, the rigidity of the cover is ensured, the brush held by the cover is also pressed against the armature with a constant pressure, the rotation of the armature becomes smooth, and the armature The gap with the magnet also becomes constant, which is convenient for the efficiency of the motor. Moreover, this elastic member 15 and both end portions 13a, 1
A screw may be inserted through 4a.

A brush locker 17 fitted into the elastic body 9, a spring 18 inserted into the locker 17, and a conductor 1 for preventing the spring 18 from popping out.
It is 9th mag.

Unlike the above, the shape of the groove formed in the elastic member 20 is changed so that both ends 13a, 14a are parallel to each other, and the protrusion length of these both ends 13a, 14a is increased. This made the connection stronger and more reliable.

なる。 In the cover configured as described above, vibrations within the flat motor, such as vibrations of the brush 7, are blocked by the elastic body 9 even if transmitted through the brush rocker 17, and are not transmitted to the cover 2. Therefore,
In this motor, the noise of the brush 7, which produces the loudest noise, is also attenuated in two wide stages (by the elastic member 15 and the elastic body 9), so it is effective not only in terms of vibration but also in terms of noise. Become something.

することになる。 In addition, before connecting the outer edge 14 and the bottom surface 13 of the cover with the elastic member 15, the work of attaching the brush 7 etc. to the bottom surface 13 and the outer edge 14 are performed in advance.
The work of attaching permanent magnets to the sides can be performed independently, improving the workability of assembling this motor.

る。 As is clear from the above description, according to the present invention, the bottom part and the outer edge part of the cover are configured separately,
Since these two ends are overlapped and connected via an elastic member, vibrations transmitted from inside and outside the motor are blocked by the elastic member, which is particularly caused by friction between the brush and the armature. The generated noise does not escape to the outside, making it possible to create a quiet motor, and the rigidity of the cover is also ensured, and the brushes held by the cover are also pressed against the armature with a constant pressure. Since the gap between the armature and the magnet is constant, it is convenient for the efficiency of the motor, and the bottom part and the outer edge part can be manufactured independently, improving work efficiency. Since the shapes of each component are simple, the manufacturing work becomes easy, and the flat motor itself can be provided at a low cost, which is an extremely excellent effect.
