1. A vehicular washing device comprising:
a nozzle that sprays a fluid toward an object to be washed;
a flow passage forming body of which an internal space is a flow passage of the 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 a diameter of the pressing tube part changes, and opens and closes the flow passage according to a state of deformation, wherein:
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; and
the valve deforms elastically according to a magnitude of a pressure of the first flow passage or a pressure of the second flow passage relative to an atmospheric pressure.
