PURPOSE:To simplify the machining and assembling and improve the accuracy of a unit by providing each set of keys respectively on the end plate of a stationary scroll and at the back of an end plate of a revolving scroll in the directions they intersect perpendicularly with each other and providing key ways on one end surface of an Oldham's ring. CONSTITUTION:A set of keys 5C for an Oldham's ring are provided radially on the end plate 1A of a stationary scroll 1, and a set of keys 5B for the Oldham's ring are also provided radially at the back of the end plate 2A of a turning frame 2 in such a direction as to intersect perpendicularly with the direction of the keys 5C. Notches 2C, into which the keys 5C on the stationary scroll 1 are freely fitted, are provided at the back of said end plate 2A. Two sets of key ways 3B and 3C corresponding respectively to said keys 5B and 5C are provided on the one end surface of an Oldham's ring 3, thereby eliminating the need for using jigs as in conventional practice, making the machining and assembling of the unit easier and reducing the manhour. |
