Abstract

PURPOSE: To prevent both an oscillation bearing and a slider sleeve from being damaged due to the deflection of an eccentric shaft section by engaging the slider sleeve with the eccentric shaft section of a main shaft in such a way as to be monolithically rotated so as to be fitted, and thereby providing a cut-off section for the lower half section of the outer circumference of the eccentric shaft section at the side which is subjected to force from the oscillation scroll side.
CONSTITUTION: The outer circumference of an eccentric shaft section 9a is provided with a cut-out section 9d for its lower half section at the side which is subjected to force from the side of an oscillation scroll 2. The points of application of force from the oscillation scroll 2 and the reaction of the eccentric shaft section 9a are made to coincide with the points of application of an oscillation bearing 11, a slider sleeve 27 and the eccentric shaft section 9a in respective contact surfaces. By this constitution, the condition between the oscillation bearing 11 and the slider sleeve 27 is a surface contact, both of them can thereby be prevented from being damaged.
