A second image producer produces, using at least one of the left-eye and right-eye original images, a second display image corresponding to an image of an area including the above partial area and being wider than that partial area.

Abstract: A flow control valve includes a resin housing body, a valve member, a retainer plate, a drive unit, and a protective wall. The resin housing body is substantially cylindrical. The valve member axially moves back and forth in the housing body to regulate a flow rate of a liquid.
