PROBLEM TO BE SOLVED: To permit dismantling of an instrument upon disposal of the same without preparing any tool differently by a method wherein the functional unit of a tool, which is capable of achieving the function of a tool necessary for the dismantling of the instrument, is ruptured or removed simply. SOLUTION: Upon disposal of a ventilating device, the initial configuration of a constitutional component or an air cylinder 3 is ruptured to separate the functional unit 1 of a tool. An impeller can be dismantled from a rotary shaft employing the separated functional unit 1 of a tool. In this case, the nut engaging port 12 of the functional unit 1 of a tool is engaged with a nut part and is turned toward the loosing side of the nut by a handle 11 whereby the nut part can be removed from the rotary shaft without preparing any special tool, and the impeller can be removed. The functional unit 1 of a tool is provided with a discriminating function, showing the tool, whereby the tool can be recognized easily and the same is convenient upon disposal of the ventilating device. The functional unit 1 of a tool will not be lost until the time of disposal whereby compatibility upon disposal is good.
