Abstract:
An air brush constructed such that a needle for opening and closing a nozzle is inserted in an axial direction along a shaft core portion of an air brush main body having the nozzle at its tip and approximately formed in a long sleeve shape so as to be advanced and retreated, and a compressed air supplied to an interior of said air brush main body through an air valve is blown out of said nozzle, and an operating rod is fitted into said air brush main body from a notch port formed on an upper face of the air brush main body, and a pushing rod is connected to a lower end of the operating rod through a pivotal portion so as to be freely bent and is fitted into the air brush main body and is supported together with said operating rod so as to be freely vertically pushed and moved, and a lower end of this pushing rod and an upper end of a valve rod for opening and closing said air valve are opposed to each other, and the air valve is opened by pushing and moving the valve rod by a pushing operation of said operating rod, and the needle is retreated in the axial direction in cooperation with an engaging body mounted into said notch port by tilting the operating rod backward, and paint supplied to the nozzle is sprayed by blowing-out the compressed air;wherein said operating rod forms a slanting face therein projected on a front face while the slanting face is inclined from below to above, and this slanting face abuts on a front side edge portion of the notch port of said air brush main body, and the air valve is opened every small amount and the needle is simultaneously retreated every small amount in a range in which the slanting face of the operating rod and a contact portion of the front side edge of the notch port come in contact with each other and are slid at an initial stage of an operation for pushing and moving said operating rod.
