A lifting and lowering device () for a toilet seat or a toilet cover has a swing shaft () provided on a swing center line (C) of a toilet seat () or a toilet cover () that swings around base end portions (), respectively, and rises. The device includes a lifting and lowering control unit () indirectly fixed to a toilet bowl main body (); an output shaft () that is provided on the swing center line (C), one end portion of which shaft being removably connected to the swing shaft () of the lifting and lowering control unit () and the other end portion being detacheably connected to the base end portion () of the toilet seat (); and a toilet seat transmission unit () containing a tortion spring () that urges the output shaft () in a lifting direction of the toilet seat (). The lifting and lowering device () 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.
