To suppress reduction in cleaning performance over a long period in a stuck article removal device for a vehicle, which increases the pressure of a cleaning liquid by pump means operated by the self-weight of the vehicle and injects the cleaning liquid toward the vehicle.SOLUTION: Pump means P includes an operation chamber A that stores a cleaning liquid W. A movable upper wall 5 of the operation chamber A has a base end 5A and a free end 5B. The base end is supported on a horizontal support shaft J. The free end 5B vertically oscillates following passage of a tire T of the vehicle. A seal body S is provided between a fixed wall C and the movable upper wall 5 forming the operation chamber A. The seal body S is supported by a support E provided in the movable upper wall 5 and can move forward and backward toward and from the fixed wall C. The seal body S advances, by the pressurizing force of the cleaning liquid W in the operation chamber A when the movable upper wall 5 oscillates downward to reduce the capacity of the operation chamber A, toward the fixed wall C, and slides on the wall surface D of the fixed wall C.SELECTED DRAWING: Figure 7

    【課題】車両の自重により作動するポンプ手段により洗浄液の圧力を高め、洗浄液を車両へ向けて噴射する車両用付着物除去装置において、長期間にわたって洗浄能力の低下を抑制する。【解決手段】ポンプ手段Pは、洗浄液Wを収容する作動室Aを有する。作動室Aの可動上壁部5は、基端部5A及び遊端部5Bを有し、基端部は、左右方向の支軸Jにより支持され、遊端部5Bは、車両のタイヤTの通過に伴って上下方向へ揺動する。作動室Aを形成する固定壁部Cと可動上壁部5との間にシール体Sを有する。シール体Sは、可動上壁部5に設けた支持部Eにより支持されて固定壁部Cへ向かって進退可能である。シール体Sは、可動上壁部5が下方へ揺動して作動室Aの容積が減少する際における作動室A内の洗浄液Wの加圧力で、固定壁部Cへ向かって進出して固定壁部Cの壁面Dを摺動する。【選択図】図7
