To provide a simple fire truck with easy movement that has improved durability of a positive-displacement pump.
There is provided a simple fire truck with easy movement that easily moves to a narrow fire occurred spot difficult for a car to enter by using a transfer wheel driven by a motor separately from a pump driven by an engine. The simple fire truck includes: a depressurization groove 200-6 that is formed between a chamber 200-1 where a sealing member 200-5 receiving pressure of the pump 200 is provided, and a suction hole 200-1a and that depressurizes a pressure of the chamber 200-1; a lubricating water supply means for improving durability through lubrication action and cooling action by supplying lubricating water to an inlet of the chamber 200-1 according to a vacuum pressure generated during an initial activation of the pump 200; and a rotor means having a first protrusion 220-1 at an end of a side of a rotor 220 provided inside the chamber 200-1, and a second protrusion 220-2 at a periphery of a shaft hole through which a rotation shaft penetrates.
