The invention relates to a device for sealing a space (10) which contains a lubricant (12) and which is located on a structural part (14) that is driven in such a way that it rotates; in relation to a second space (16), especially on a pin of a manually operated machine tool, with at least one seal (20) which slides on a contact surface (18). According to the invention, at least one stationary structural part (28) is situated in the space (10) that is filled with lubricant (20), in front of the contact surface (18). Said stationary structural part encloses the structural part that is driven to rotate in at least one area of its periphery and at least substantially prevents swirls in the lubricant (20) in the area of the contact surface (18).
