The lock lever falls down and engages with the operation lever when the operation lever is pulled forward; Is intended to be manually disengageable.

[0008]

When the valve mounted so as to be located in the lid is switched to the communication position with the door closing solenoid valve by manual switching means, pressurized air enters the door closing solenoid valve through the internal passage from the air supply hole of the lid. By switching the door closing solenoid valve, pressurized air is supplied to the rod side chamber or the opposite rod side chamber of the drive cylinder, and the door opens and closes. When the valve body is switched to the open position for the door-closing solenoid valve by the manual switching means, the pressure air to the door-closing solenoid valve is shut off and communicates with the atmosphere, and both the rod side chamber and the non-rod side chamber of the drive cylinder communicate with the atmosphere. , The door can be opened and closed manually. Therefore, there is no need for actual piping for the valve element, and the valve is made compact.

When the valve body is switched to the open position by the manual switching means, the door is manually opened, but the hand touches the manual switching means when the passenger gets off, or the passenger pushes back the inspection lid covering the manual switching means. However, the position of the manual switching means is fixed by the locking means, and the door is not closed due to inadvertent switching to the communication position.
