• the case cover including
• an extending portion, a height of the extending portion becoming low toward forward, and
• a toilet seat pivot support portion provided backward the extending portion, and pivotally supporting the toilet seat,
• the toilet seat including
• a first portion positioned forward the case cover in the closed state, and
• a second portion rising backward from the first portion in the closed state, overlapping the extending portion, and being pivotally supported to the toilet seat pivot support portion,
• an upper end surface of the toilet seat pivot support portion changing to lower a height toward forward, and forming a generally continuous surface to an upper end surface of the second portion,
• a first angle between a virtual line and a first tangent line being not more than 5°, the virtual line being a virtual line connecting the rear end of the upper end surface of the second portion to the front end of the upper end surface of the toilet seat pivot support portion, the first tangent line being a tangent line to the rear end portion of the upper end surface of the second portion, and
• a second angle between the virtual line and a second tangent line being not more than 5°, the second tangent line being a tangent line to the front end portion of the upper end surface of the toilet seat pivot support portion.
