Malfunction due to expansion of a fluid is eliminated to ensure a normal operating state. A vehicular washing device includes: a nozzle 4 that sprays a fluid toward an object to be washed; a flow passage forming body 2 of which an internal space is a flow passage of the fluid; and a valve 21 that has a pressing tube part 22 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 2a and a second flow passage 2b are formed as the flow passage on opposite sides of the pressing tube part. A shaft 9 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.
