Abstract

A downstream-side passage of an expansion valve includes a small-diameter part to which a valve hole and an insertion hole are open, and a large-diameter part to which a pipe leading to an evaporator is connected. A plate has a shield part partially covering a downstream end of the small-diameter part. The shield part has a height of 2 mm or larger in a radial direction of the small-diameter part from a projected position of an opening of the insertion hole at the downstream end of the small-diameter part, and a width equal to or larger than a radius of the shaft within a range of the height. The plate is provided so that the shield part does not cover at least a range of projection of an opening of the valve hole at the downstream end of the small-diameter part.
