It addition, as it has been described above, in the present embodiment, by eccentric bush 83 relative to crank-pin Loosening between rotation and restriction projection 83b and limiting holes 28d of 82, it is possible to convolution whirlpool dish 52 Radius of turn and driven crank mechanism 81 in radius of turn between deviation absorb, but also can adopt With the driven crank mechanism of slidingtype, in the driven crank mechanism of this slidingtype, make crank-pin 82 and be located at The crank pin hole 83a of eccentric bush 83 is rectangle, and by making eccentric bush 83 relative to crank Pin 82 can radially be slidably inserted into, and thereby, the deviation of radius of gyration is absorbed (such as, ginseng Fig. 6 according to Japanese Patent Laid-Open 2006-342793).

It addition, in said pump one-piece type expansion apparatus 29A, due to B > C and A > B, therefore, When making pump unit 60 integrated with expansion cell 50, at eccentric bush 83 relative to driving bearing 56 After starting to be fitted together to, O 94 starts chimeric with little inside diameter 54b.

Therefore, Qian He by O 94 with little inside diameter 54b, come in pump unit 60 and Before relative motion between expansion cell 50 limits, it is possible to by eccentric bush 83 and drive shaft Hold the aligned in position of 56, thus can easily carry out position adjustments.

In contrast, when eccentric bush 83 start with driving bearing 56 chimeric before, O shape Ring 94 begin to chimeric with little inside diameter 54b in the case of, i.e. at B > in the case of A, being difficult to will Pump unit 60 moves relative to expansion cell 50, thus is difficult to carry out eccentric bush 83 and driving bearing Position adjustments between 56.

So, meeting A > in the said pump one-piece type expansion apparatus 29A of B > C, make pump unit 60 Time integrated with expansion cell 50, it is possible to eccentric bush 83 is easily chimeric with driving bearing 56, Therefore, it is possible to improve the operability of integration.
