A lifting and lowering device ( 31 ) for a toilet seat or a toilet cover has a swing shaft ( 17 ) provided on a swing center line (C) of a toilet seat ( 3 ) or a toilet cover ( 4 ) that swings around base end portions ( 3 l, 4 l), respectively, and rises. The device includes a lifting and lowering control unit ( 5 ) indirectly fixed to a toilet bowl main body ( 30 ); an output shaft ( 12 ) that is provided on the swing center line (C), one end portion of which shaft being removably connected to the swing shaft ( 17 ) of the lifting and lowering control unit ( 5 ) and the other end portion being detacheably connected to the base end portion ( 3 l) of the toilet seat ( 3 ); and a toilet seat transmission unit ( 9 ) containing a tortion spring ( 13 ) that urges the output shaft ( 12 ) in a lifting direction of the toilet seat ( 3 ). The lifting and lowering device ( 31 ) for the toilet seat of toilet cover is relatively small in size and able to stabely hold the toilet seat or toilet cover in a raised position. Commonality of structural parts can be achieved depending on the magunitude of torque caused by the self weight of the toilet seat or toilet cover.
