つた。[Prior Art and Problems to be Solved] Conventionally, in the emergency closing device for the bottom valve of this type of tank truck, when a fire occurs when unloading a hazardous liquid loaded in a tank, all In order to close the bottom valves of the tank and stop the discharge, an emergency lever is provided at the rear of the tank, away from the discharge valve on the side of the tank where the discharge hose is connected, to close all the bottom valves at the same time. When a fire breaks out near this emergency lever, the flammable or easily soluble material installed near this lever burns or melts, and the bar, whose biasing force is blocked by this material, is activated and the emergency lever is activated. A lever was actuated to close all bottom valves simultaneously. A structure in which the emergency lever is mechanically operated by a plucked strip whose biasing force is blocked by a flammable or easily soluble material has a complicated structure and cannot be manufactured at a low cost. In order to operate reliably, a strong repellent is required, the structure becomes large, and a large force is required to block the biasing force, making assembly difficult.
