PROBLEM TO BE SOLVED: To protect a driving motor and a driving means from an abnormal overload even if a toilet seat and a toilet cover are forcibly turned in the closing direction or the opening direction before the toilet seat and the toilet cover reach the closing position in the case of controlling the toilet seat and toilet cover opening and closing operation with a computer through the driving motor and the driving means. SOLUTION: When the toilet cover driving motor and the toilet seat driving motor are rotated (S32) and a determination that the number of the rotation pulse is counted up is done (S35: Yes), a determination that the toilet seat and the toilet cover exist on just this side of the closing position is done, and the rotation of the toilet cover driving motor and the toilet seat driving motor is braked (S36). When braking, if the toilet seat and the toilet cover are forcibly turned by the external force, a toilet cover limit switch and a toilet seat limit switch are closed (S37: No), and current-carrying to the toilet cover driving motor and the toilet seat driving motor is stopped, and braking to the rotation of the toilet cover driving motor and the toilet seat driving motor is released (S44).
