Document Type and Number:
Japanese Patent JP2005220868
Kind Code:
A
Abstract:
To provide a bearing structure of a compressor decreasing rotational resistance of a drive shaft, reducing a part number on a front side and easy to assemble.
A through hole 20 is formed in a front wall of a front housing 5 and a bearing hole 21 increasing in diameter backward is formed behind the through hole 20. A journal portion 24 of an almost conical shape is formed on a front end of a drive rotor 11 integral with the drive shaft 10 and is fitted in the bearing hole 21. The bearing hole 21 and the journal portion 24 are rotated and slid with an inclination of an inner surface of the bearding hole and an inclination of a peripheral surface of the journal portion 24 made the same.
