13. A pneumatic tool, comprising:
-
a tool body, a nose part for ejecting a nail, which is provided in a lower part of said tool body, an air chamber for storing compressed air, which is provided in said tool body, an air supply pipe for supplying the compressed air from an air supply source to said air chamber, an air duster, an air duster pipeline connected to an air outlet of said air duster, and an air duster valve for controlling supply of the compressed air to said air duster pipeline, wherein an operating pipeline is branched from said air chamber, one end of said air duster pipeline is branched from said air supply pipe, while the other end of said air duster pipeline is connected to the air outlet of said air duster, said air duster valve includes a selection valve which is provided in a branch part where said air duster pipeline is branched from said air supply pipe, said operating pipeline is connected to said selection valve by way of an opening and closing valve to be operated by an operating button, and said selection valve has a valve element which is movable between a first position where an upstream side pipeline leading to said air supply source is opened to a downstream side pipeline leading to said air chamber for storing the compressed air and shut off with respect to said air duster pipeline, and a second position where said upstream side pipeline leading to said air supply source is shut off with respect to said downstream side pipeline and opened to said air duster pipeline, wherein when said operating pipeline is closed by said operating button, said valve element is moved to the first position, and when said operating pipeline is opened by said operating button, said valve element is moved to the second position, and wherein the air outlet of said air duster is arranged in vicinity of said nose part, and a direction of blowing out the air from said air duster is substantially the same as a direction of ejecting a fastener by said tool body.

14. A pneumatic tool, comprising:
-
a tool body, a nose part for ejecting a nail, which is provided in a lower part of said tool body, an air chamber for storing compressed air, which is provided in said tool body, an air supply pipe for supplying the compressed air from an air supply source to said air chamber, an air duster, an air duster pipeline connected to an air outlet of said air duster, and an air duster valve for controlling supply of the compressed air to said air duster pipeline, wherein an operating pipeline is branched from said air chamber, one end of said air duster pipeline is branched from said air supply pipe, while the other end of said air duster pipeline is connected to the air outlet of said air duster, said air duster valve includes a selection valve which is provided in a branch part where said air duster pipeline is branched from said air supply pipe, said operating pipeline is connected to said selection valve by way of an opening and closing valve to be operated by an operating button, and said selection valve has a valve element which is movable between a first position where an upstream side pipeline leading to said air supply source is opened to a downstream side pipeline leading to said air chamber for storing the compressed air and shut off with respect to said air duster pipeline, and a second position where said upstream side pipeline leading to said air supply source is shut off with respect to said downstream side pipeline and opened to said air duster pipeline, wherein when said operating pipeline is closed by said operating button, said valve element is moved to the first position, and when said operating pipeline is opened by said operating button, said valve element is moved to the second position, and wherein said operating button is disposed on a side face of said tool body, within a reach of a thumb or an index finger of a worker who has gripped said tool body.
