Abstract: This pressure-reducing valve includes: a casing in which a valve passage is formed; a valve body that is movably housed in the casing and changes a position thereof according to a secondary pressure to adjust an opening degree of the valve passage; and a biasing member that biases the valve body against the secondary pressure in an opening direction in which the valve passage opens. The biasing member is a spring in the form of a plate and extends laterally from the valve body.
