EGR VALVE AND EGR VALVE DEVICE PROVIDED WITH SAME

A poppet-type EGR valve includes: a housing that includes a flow passage; a valve seat; a valve body allowed to be seated on the valve seat; a valve shaft on which the valve body is provided at one end section thereof; and a drive unit reciprocally driving the valve shaft. The flow passage has an inlet and an outlet and includes a bent passage portion that is bent downstream from the valve seat in a direction perpendicular to the direction toward the inlet. The bent passage portion includes at least one of a section in which the passage area is constant and a section in which the passage area increases toward the downstream direction, and does not include a section in which the passage area decreases toward the downstream direction. In the section in which the passage area increases toward the downstream direction, the passage area changes gradually.
