本発明はフラツトモーターの磁石固定装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnet fixing device for a flat motor.
従来、一般にフラツトモーターの磁石は、第１
図に示すように、ヨーク(イ)の上に磁石(ロ)を乗せて
接着剤を塗布するものであるが、接着剤が硬化す
るまでの間、軸と直角な方向の位置決めがなく、
磁石が硬化するまでの間移動してしまうという欠
点があつた。 Conventionally, the magnet of a flat motor is generally
As shown in the figure, the adhesive is applied by placing a magnet (B) on top of the yoke (A), but until the adhesive hardens, there is no positioning in the direction perpendicular to the axis.
The drawback was that the magnet would move until it hardened.
磁石が移動した場合、磁石がヨーク(イ)の外周か
らはみ出してケース(ハ)とヨーク(イ)との嵌合ができ
ないことがある。 If the magnet moves, the magnet may protrude from the outer periphery of the yoke (A), making it impossible to fit the case (C) and the yoke (A) together.

るようにしたものである。 In addition, in the embodiment shown in Fig. 2, adhesive (d) is applied to the contact surface between the yoke (a) and the magnet mounting piece (b), and the adhesive (d) is applied between the yoke (a) and the magnet (b). However, the disadvantage is that a hardened adhesive layer is formed, which increases the air gap and causes a decrease in motor characteristics (torque). The present invention improves these drawbacks and makes it possible to accurately fix the rotor formed by simultaneous molding.
