A scroll type compressor comprising: a fixed scroll; a movable scroll engaged with the fixed scroll; and a hermetically sealed container in which the fixed scroll and the movable scroll are mounted, wherein one scroll of the fixed scroll and the movable scroll includes: an intercommunication path that is opened to the outside of the one scroll at one end thereof, extends substantially in a radial direction of the one scroll, has a high-pressure opening intercommunicating with a high-pressure portion of the hermetically sealed container and a low-pressure opening intercommunicating with a low-pressure portion in the one scroll, and has a lower hole opened to the outside of the one scroll and an insertion hole formed by subjecting the lower hole to reaming processing from the one end to a position of a predetermined depth of the lower hole, oil being supplied from the high-pressure opening through the inside of the intercommunication path to the low-pressure opening; a pin member that is configured to be slightly smaller in diameter than the intercommunication path and movably inserted in the intercommunication path; and characterised by a screw member that is provided at one end of the intercommunication path to close the one end of the intercommunication path so as to press the pin member against the end of the back side of the intercommunication path. a fixed scroll; a movable scroll engaged with the fixed scroll; and a hermetically sealed container in which the fixed scroll and the movable scroll are mounted, wherein one scroll of the fixed scroll and the movable scroll includes: an intercommunication path that is opened to the outside of the one scroll at one end thereof, extends substantially in a radial direction of the one scroll, has a high-pressure opening intercommunicating with a high-pressure portion of the hermetically sealed container and a low-pressure opening intercommunicating with a low-pressure portion in the one scroll, and has a lower hole opened to the outside of the one scroll and an insertion hole formed by subjecting the lower hole to reaming processing from the one end to a position of a predetermined depth of the lower hole, oil being supplied from the high-pressure opening through the inside of the intercommunication path to the low-pressure opening; a pin member that is configured to be slightly smaller in diameter than the intercommunication path and movably inserted in the intercommunication path; and characterised by a screw member that is provided at one end of the intercommunication path to close the one end of the intercommunication path so as to press the pin member against the end of the back side of the intercommunication path. an intercommunication path that is opened to the outside of the one scroll at one end thereof, extends substantially in a radial direction of the one scroll, has a high-pressure opening intercommunicating with a high-pressure portion of the hermetically sealed container and a low-pressure opening intercommunicating with a low-pressure portion in the one scroll, and has a lower hole opened to the outside of the one scroll and an insertion hole formed by subjecting the lower hole to reaming processing from the one end to a position of a predetermined depth of the lower hole, oil being supplied from the high-pressure opening through the inside of the intercommunication path to the low-pressure opening; a pin member that is configured to be slightly smaller in diameter than the intercommunication path and movably inserted in the intercommunication path; and characterised by a screw member that is provided at one end of the intercommunication path to close the one end of the intercommunication path so as to press the pin member against the end of the back side of the intercommunication path.
