PURPOSE: To prevent abnormal wear from being generated and to improve the inner wheel pressure of a roller clutch by fitting a push spring and a roller in a still state on an outer wheel side so as not to be rotated integrally with a dehydrating shaft.
CONSTITUTION: An outer wheel 50 of a downstream side bearing supporting a dehydrating shaft 49 is pressed into a lower metal case 51 and constituted integrally with an inner wheel 52 of this bearing. In the upper part of the bearing outer wheel 50, an outer wheel 53 of the roller clutch is arranged, pressed and held into the lower metal case 51. The roller clutch inner wheel 52 is abutted to a step part 54 in a thrust direction provided in the dehydrating shaft 49 and equipped with structure wholly receiving a thrust. The load of this thrust is received by the bearing through the inner wheel of a ball bearing integral with the roller clutch inner wheel 52 so as to prevent the thrust load to the roller clutch or vibration in the thrust direction. In the roller clutch outer wheel 53, a ratchet groove 55 and a push spring 56 are provided and a roller 57 is set on the inside of this ratchet groove 55. For the roller 67, fitting boards 58 and 59 are vertically arranged so that the roller 57 can not vertically run away.
