PROBLEM TO BE SOLVED: To eliminate necessity of sealing property between a plurality of parts of a nozzle for washing a private part even when the nozzle for washing the private part is divided into the plurality of parts and its whole length is shortened and to reduce size of an operation part including a hose as much as possible. SOLUTION: This nozzle unit of the hot water washing toilet seat is provided with a rack 9 meshing with a pinion 6 rotated by rotation of a motor 7, reciprocating, and made of a bendable material having large elasticity, the nozzle 13 for washing the private part to which one end of the rack 9 reducing the whole length by achievement of many steps and allowing free expansion and contraction in the direction of length is attached, the hose 10 for supplying washing water whose one end part is attached to the nozzle 13 for washing the private part and which is made of a bendable material, and a storage part 70 holding the other end part of the rack 9 and the other end part of the hose 10, allowing reciprocating movement of the rack 9 and the hose 10 to move freely along a curved face, and storing a part of the hose 10. Consequently, a space in substantially a central part of a toilet seat main body occupied by a conventional nozzle for washing a private part is greatly contracted by the nozzle 13 for washing the private part shortening the whole length by achievement of many steps.
