続した、 ことを特徴とする鉄道車両用空気式ワイパ装置。[Claims for Utility Model Registration] A drive cylinder that reciprocates a wiper arm between a stop position and a reverse position by supplying and discharging pressurized air; A switching valve that automatically switches supply and exhaust, a lock cylinder that holds the wiper arm at a stop position when pressurized air is supplied, and an operation valve that supplies pressurized air to the lock cylinder and the switching valve. In the pneumatic wiper device for a railway vehicle, a solenoid valve is interposed between the operation valve and the lock cylinder, the solenoid valve supplies air to the lock cylinder when the coil is demagnetized, and supplies air to the lock cylinder when the coil is energized. a solenoid valve for exhausting the wiper arm, a first series circuit consisting of a detection switch that detects the reverse position of the wiper arm and turns it off, and an on-delay type timer relay, and the delay time of the timer relay is used as the return movement of the wiper arm. A second series circuit consisting of the normally open timer contact of the timer relay and the coil of the solenoid valve is connected in parallel to the first series circuit, and this parallel circuit is connected to the power supply via an intermittent switch. A pneumatic wiper device for a railway vehicle, characterized in that the wiper device is connected to a pneumatic wiper device.
