<P>PROBLEM TO BE SOLVED: To provide a cold storage refrigerator capable of reducing an amount of lubricant flowing out of an inner space of a bearing member, reducing an amount of foreign objects mixed into the inner space of the bearing member, and preventing deformation of a sealing member of the bearing member. <P>SOLUTION: The cold storage refrigerator includes: a cylinder; a cold accumulator; a rotary drive unit generating driving force for reciprocating the cold accumulator; a rotary member 31a being driven and rotated by the rotary drive unit; an inner wheel member 61 and an outer wheel member 62 provided to relatively rotate around the same rotary shaft RA; and the bearing member 60 including two sealing members 63-1, 63-2 respectively provided to both front/back sides of the inner wheel member 61 and the outer wheel member 62 along the rotary shaft RA for rotatably supporting the rotary member 31a. The sealing members 63-1, 63-2 are fixed to one of the inner wheel member 61 and the outer wheel member 62, and a gap G is formed between the wheel member fixed with the sealing members and the other wheel member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
