Claims (4)

A water supply unit for supplying water;
A throttle part for reducing the flow passage cross-sectional area than the water supply part, accelerating the water supplied from the water supply part and injecting it downstream,
An air mixing part in which an opening for introducing air for mixing air into water jetted from the throttle part to form bubble mixed water is formed;
A water spray unit provided on the downstream side of the air mixing unit and formed with a plurality of water spray holes for discharging bubble mixed water, and a shower device comprising:
The jet water imaginary straight line obtained by extending the water jetted from the throttle portion in the jet direction excludes the tip inner wall that functions as a channel end among the channel inner walls forming the channel downstream of the throttle portion. It is configured not to interfere with the inner wall,

The shower device according to claim 1, wherein the adjacent projecting portions are connected so as to form a curved portion that is concavely curved toward the downstream in a plan view . The shower apparatus according to claim 2, wherein the most downstream sprinkling hole is disposed at a downstream end of the curved portion . In plan view, the width of the protrusion, the shower device according to any one of claims 1 to 3, characterized in that smaller toward the upstream side.
