ABSTRACT:
An automatic lifting and lowering device for a toilet seat or a toilet cover usable for a toilet seat provided with a function of washing a body with hot water, which requires reduced size and weight, includes a rotating shaft (40) rotated together with the toilet seat or the toilet cover, a drive motor (32) rotating the rotating shaft (40) in normal and reverse directions, and a speed reduction gear train (33). The drive force of the drive motor (32) is transmitted to the rotating shaft (40) through the speed reduction gear train (33) to automatically lift and lower the toilet seat or toilet cover, whereby the automatic lifting and lowering device itself can be formed compact by using a planetary gear mechanism for the speed reduction gear train (33).
