Abstract

The invention relates to a expansion joint (7) for a household appliance (1), comprising a first rail (8) and a separate second rail (9) which is connected to the first rail (8). The rails (8, 9) can be displaced in a displacement direction in the direction of the longitudinal axis (L) relative to each other by means of a rolling body device (12). Said rolling body device (12) comprises a rolling cage (11) in which at least one rolling body (14, 23) is rotationally mounted, said rolling body (14, 23) comprises an axle bearing (15, 39) which is arranged on the rolling body cage (11) and the rolling bodies (14, 23) comprise a running element (16, 35) which is arranged so as to rotate about the axle bearing (15, 39), the running element (16, 35) is arranged in a recess (17) of the rolling body cage (11) and at a distance to the defining walls (19, 20, 21, 22) of the recess (17). The invention relates to a household appliance (1) having at least one expansion joint (7).
