A base plate (50) on the toilet bowl has a forward bearing (56), rearward bearing (58) and a central bearing (60). An input shaft (64) on the rearward bearing has a first gear (66), a second gear (68) and an intermediate slip clutch (70). An output shaft (72) on the forward bearing extends through the bore. A third gear (74) and a lifting arm (76) are coupled to the toilet seat. An intermediate shaft (78) on the central bearing has a fourth gear (80) in contact with the second and third gears. A motor (86) with a pinion (88) is coupled to the first gear. A switch (90) actuates the motor.
