Abstract

The invention relates to a rolling element (3) for supporting a rolling element (1) for guiding and / or supporting a front-side or rear-side section of a laundry drum of a laundry treatment appliance designed as a front loader. The rolling body has at least one tyre part (4) which can be brought into contact with the laundry drum and at least one rim (5) which is arranged radially inward relative to the tyre part (4). In order to provide a cost-effective, reliable and space-saving support roller (1), at least one positively locking structure acting in the circumferential direction is formed between the tyre part (4) and the rim (5).

Description
