Abstract
A supply port receives supply of washing liquid. An oscillation chamber oscillates the washing liquid supplied through the supply port. A jetting section jets the washing liquid oscillated in the oscillation chamber to the outside. The jetting section includes a passage connecting the oscillation chamber and the outside. The washing liquid enters the passage from the oscillation chamber through an entrance, passing through the passage, and emitted through an exit to the outside. A jet port is provided between the entrance and the exit, having a narrower width than those of the entrance and the exit. An outer guide connects the jet port and the exit. An inner guide connects the entrance and the jet port, and configured to conduct the liquid oscillated in the oscillation chamber to the outer guide.
