Abstract:
PURPOSE:To prevent one side contact by making at least one of two keys provided on an Oldham's link contact with the side wall of a key groove in the direction where a rotary shaft rotates with its side surface. CONSTITUTION:A first key 301 is fit in a groove 311 on the upper surface of a casing 6 free to slide in it and a second key 302 is fit in a groove provided on the back surface of a revolving scroll free to slide in it respectively. One side wall 311a of the groove 311 is in the rotary direction of a rotary shaft and it is arranged on the straight line passing the center of the casing 6. A side surface 301a of the first key 301 provided on the surface of an Oldham's link 3 facing against the casing 6 is made to match the side wall 311a. By getting rid of a space between the keys and the groove, torsion of the Oldham's link is prevented and one side contact with the groove is prevented.
