<p>A diffusion restriction portion (38, 40, 56, 58, 74, 88, 98) is provided to a washer nozzle (10) of a washer device (X) to be opened outside along a direction, in which diffusive flow of cleansing liquid causing self-oscillation is jetted as a sector-shaped diffusive flow in its widthwise direction of the vehicle. Besides, the jetted diffusive flow is restricted in diffusion in its vertical direction by the diffusion restriction portion (38, 40, 56, 58, 74, 88, 98) to be regulated. The washer nozzle (10) is arranged on a back surface side of a rear end edge of an engine hood (F) of a vehicle, and wiper arms (W) are arranged lengthwise along the widthwise direction of the vehicle when being in a stopped position. Even in this case, the jetted diffusive flow can be sprinkled over a wide range in the widthwise direction of the vehicle. Besides, the diffusive flow can be sprinkled on a target sprinkle point from a narrow gap between the wiper arms (W) and the rear end edge of the engine hood (F) without interference. <IMAGE></p> |
