にスパッタが侵入しないようにしている。In FIG. 1, ■ is a compressor main body, 2 is a bottom chamber, and 3 is a lid chamber, and the compressor main body 1 is attached to the bottom chamber by electric welding. bottom chamber 2
There is refrigerating machine oil 7 at the bottom of the bottom chamber 2, and the magnet holding device 6 of the present invention is attached to the bottom chamber 2 so as to be immersed in the refrigerating machine oil 7. A magnet 5 is attached to this magnet holding device 6. The lower part of the compressor body near the magnet 5 is equipped with an oil supply device 4, and when refrigerating machine oil is sucked from there, the lid, bottom chambers 3, 2, and
Spatter generated during electric welding between the compressor main body 1 and the bottom chamber 2 is attracted to the magnet 5 to prevent the spatter from entering the moving parts of the compressor.
本発明は、この磁石５を保持する磁石保持装置６に関す
るもので、以下第２図、第３図、第４図により説明する
。The present invention relates to a magnet holding device 6 that holds this magnet 5, and will be explained below with reference to FIGS. 2, 3, and 4.
第２図は、本発明の磁石保持装置６の平面図を示す。第
２図に示すように、上側両側には、内側に伸びた爪６ａ

。FIG. 2 shows a plan view of the magnet holding device 6 of the present invention. As shown in FIG. 2, there are claws 6a extending inward on both upper sides.
At one end in the direction perpendicular to this, there is a claw 6b that stands up vertically, and an arm 6c that extends in the opposite direction.
A claw 6d raised upward is provided on the inside of the tip.
また、第３図は、第２図の縦断面図で、中央部に凹部６
ｅを有していることを示す。FIG. 3 is a vertical cross-sectional view of FIG. 2, with a recess 6 in the center.
It shows that it has e.
一方、この四部６ｅは、この部分が、底チャンバ２との
