CLOSED TYPE ELECTRIC COMPRESSOR

PROBLEM TO BE SOLVED: To provide a compressor which can reliably lock a rotor at the locking surface of a main shaft part and is high in reliability and low in height. SOLUTION: The compressor contains an electric element consisting of a stator and a rotor 10; and a compression element driven by the electric element. The compression element is provided with a crank shaft 150 having a main shaft part 151 and an eccentric part 152; and a cylinder block 155 fixing the stator and forming a bearing part 157 pivoting the main shaft part 151. The rotor 104 forms approximately a cylindrical shape and has an element part 160 containing a permanent magnet 165, a female screw 174 situated at a cylinder bore, and a boss part 161 supporting the base of the element part 160. A screw part 153 is situated at the main shaft part of the crank shaft 150. A fixing force is improved by threadedly mounting the boss part 161, and reliable fixing can be executed even if the length of a threadedly mounting part is short. COPYRIGHT: (C)2006,JPO&NCIPI
