Abstract
A vehicular washing device includes: a nozzle (); a flow passage forming body () of which an internal space is a flow passage of a fluid; and a valve () that has a pressing tube part () with an axial direction coinciding with a flow direction of the fluid, is elastically deformable in a direction in which the diameter of the pressing tube part changes, and opens and closes the flow passage according to the state of deformation. A first flow passage () and a second flow passage () are formed as the flow passage on opposite sides of the pressing tube part. A shaft () with which the pressing tube part is capable of coming into close contact is located inside the valve. The valve deforms elastically according to the magnitude of the pressure of the first flow passage or the pressure of the second flow passage relative to an atmospheric pressure.
