PROBLEM TO BE SOLVED: To provide a bidet capable of injecting wash water only into a private part without wetting an unnecessary part with a simple structure. SOLUTION: A disk-like restraining valve 26 is incorporated into a rear end opening part of a slider 8. An almost S-shaped cutout 40 is arranged in the restraining valve 26, and the cutout 40 opens by hydraulic pressure after the slider 8 reaches an advance-retreat limit to inject the wash water into the private part from tip attachments 15a and 15b. Since the cutout 40 does not open in the middle of advancing and retreating the slider 8, injection of the wash water can be restrained.
