To shorten the overall length of a vehicular washing device.SOLUTION: A vehicular washing device 1 includes: a cylinder 8 including a cylinder cylindrical portion 10 and a coupling portion 18 coupled to an outer periphery of the cylinder cylindrical portion 10, disposed in communication with the cylinder cylindrical portion 10 through an inflow port 10g formed in the outer periphery, and coupled, via a tube, to a washing fluid storage tank provided in a vehicle body; a piston 12 including a piston cylindrical portion 20 that is movably inserted into the cylinder cylindrical portion 10 and whose both end are open; and an injection nozzle portion 14 attached to a leading end 12a, in an extending direction, of the piston cylindrical portion 20 projecting from the cylinder cylindrical portion 10, and configured to inject a washing fluid F, supplied through the piston cylindrical portion 20, toward a to-be-washed object. The coupling portion 18 is coupled to an outer periphery, on an opposite injection nozzle portion side, of the cylinder cylindrical portion 10. The piston cylindrical portion 20 and a channel 18a for a washing fluid in the coupling portion 18 overlap when the piston 12 is in a storage position and the coupling portion 18 is viewed in a direction orthogonal to the extending direction.SELECTED DRAWING: Figure 2

    【課題】車両用洗浄装置の全長を短くする。【解決手段】車両用洗浄装置1は、シリンダ筒部10と、シリンダ筒部10の外周に結合され、当該外周に形成された流入口10gを通じてシリンダ筒部10に連通され、車体内部に設けられる洗浄流体貯留タンクとチューブを介して連結される連結部18と、を含むシリンダ8と、シリンダ筒部10内に移動可能に挿入される両端が開口したピストン筒部20を含むピストン12と、シリンダ筒部10から突出するピストン筒部20の延在方向の先端12aに取り付けられ、ピストン筒部20内を通って供給される洗浄流体Fを被洗浄物へ向けて噴射する噴射ノズル部14と、を備える。連結部18は、シリンダ筒部10の反噴射ノズル部側の外周に結合される。ピストン12が収納位置にあり、かつ、延在方向に直交する方向に連結部18を見たとき、ピストン筒部20と連結部18内の洗浄流体の流路18aとが重なる。【選択図】図2
