Abstract
Provided is a flow rate adjusting device in which a body portion having a valve hole includes: an annular wall portion that partitions a downstream-side fluid chamber into an inside flow channel annularly formed around a valve body portion and an outside flow channel annularly formed at an outside of the inside flow channel; an outflow hole that guides the fluid circulating in the outside flow channel to an outflow-side flow channel; and a blocking wall that blocks the fluid having reached the outflow hole from flowing around the outside flow channel. The annular wall portion includes a communication flow channel that guides the fluid from the inside flow channel to the outside flow channel. The communication flow channel guides the fluid to a location that is adjacent to the blocking wall and is isolated from the outflow hole by the blocking wall.
