BIDET

PROBLEM TO BE SOLVED: To provide a bidet with which the flushing of the backside and the parts can be conducted by one flushing nozzle while a feeling of proper use can be imparted for every use site. SOLUTION: Since a cylinder 21, in which a flushing-water inflow port 21k is formed at one end and an opening section 21p at the other end, a hydraulic type nozzle 23, in which a flushing-water introducing port 23k is formed at one end and a nozzle at the other end, which is positioned in superposition relation with the cylinder 21 and is elongated to the cylinder 21 at the water pressure of water flowing in from the flushing-water inflow port 21k and ejects flushing water and to which a plurality of nozzles 23c, 23d are formed, and a selective means 25 selecting either one of a plurality of the nozzles by the elongation length of the hydraulic type nozzle 23 are installed, nozzle themselves can be selected by altering the nozzle elongation length by the changeover of the backside/the bidet by the single cylinder. Thus, flushing can be conducted in flushing form (a flow rate, the range of ejection and the angle of ejection) optimum for the backside/the bidet.
