ABSTRACT:
A processing tool for mixing or comminuting food materials includes a working shaft having an input end and an output end, a shaft housing which carries the input end and is adapted for coupling to a drive motor of a kitchen appliance, a flared bell-shaped housing attached to the shaft housing and positioned near the output end of the working shaft, and a bearing sleeve which carries the output end of the working shaft. A cover plate separates an inner space defined by the bell-shaped housing from an inner space defined by the shaft housing. The cover plate has a bore through which the output end of the shaft extends outwardly. A work performing element is secured to the output end of the shaft. A seal structure includes an elastic sealing part supported by the shaft housing and a circumferential sealing ring formed integrally with the elastic sealing part. The bearing sleeve is inserted into the elastic sealing part, and the elastic sealing part is arranged between an outer circumferential area of the cover plate and the bell-shaped housing. The elastic sealing part and the sealing ring operate to center the bearing sleeve elastically.
