Abstract

PROBLEM TO BE SOLVED: To prevent overkneading at the time of kneading a bread material by fitting a frictive bearing for transmitting driving force by means of fixed force lower than the frictive one between a driving shaft and a kneading blade arranged in a bread container. SOLUTION: When the bread material is set in the kneading container 1 at the time of automatic bread making so as to start it, a motor disposed in a main body is rotated, the kneading blade 2 is rotated with a driving transmission mechanism, a connector 6 and the driving shaft 3 and the bread material is stirred and kneaded. When the viscosity of bread dough reaches the prescribed one, a frictive bearing inner wheel 8 and a frictive bearing outer wheel 9 start sliding by the actuation of the frictive bearing which is held between the driving shaft 3 and the kneading blade 2 so as to transmit driving force by fixed force being lower than the frictive one so that overkneading is prevented. Besides, at this time, a one-way clutch can be arranged in parallel with the frictive bearing between the driving shaft and the kneading blade 2 and the kneading blade 2 is rotated by the rotation of the driving shart 3 together with the one- way clutch so that a degassing operation is surely executed.
