<p>Disclosed is a buffering member which is capable of easily linking an output shaft and a passive shaft so as not to cause misalignment or looseness of the shaft centers, and which is capable of suppressing outside forces working directly from one of the shafts towards the other of the shafts and of suppressing the effects caused by thermal conductivity and thermal expansion; also disclosed is a uniaxial eccentric screw pump provided with said buffering member. By being interposed between an output shaft (70a) and a drive shaft (56), a buffering member (82) is capable of linking both shafts. The buffering member (82) is made from a resin, and has a tubular buffering member main body (84) and a coupling means (90). By being inserted into a buffering member insertion area (56a) disposed on the end of the drive shaft (56), the buffering member main body (84) assumes a state in which said buffering member main body (84) is fitted in and coupled with the drive shaft. Further, by inserting an output shaft (70a) into an insertion area (88) disposed on the buffering member main body (84) and engaging with a key seat (70b) a key (92) which forms a coupling means, the output shaft (70a) and the buffering member main body (84) assume a linked state.</p> |
