ABSTRACT:
A variable capacity rotary compressor including upper and lower compression chambers in which compressing operations are carried out. A slot is provided at a predetermined position between upper and lower eccentric bushes. A locking pin makes either of the upper and lower eccentric bushes be disposed at a maximum eccentric position. Since the locking pin has a diameter which is larger than a locking hole in a shaft by about 0.02 mm to 0.06 mm, the locking pin is fitted into the locking hole in a press-fit method. Further, the locking hole has a threaded part and a non-threaded part, and the locking pin has a threaded part to correspond to the threaded part of the locking hole and a non-threaded part to correspond to the non-threaded part of the locking hole.
