Patent ID: 7950557

Claim:
A pneumatic tool with an air duster comprising: an upstream side duct which communicates with an air supply source of compressed air; a downstream side duct which communicates with the pneumatic tool; an air duster branch duct; and a valve mechanism which switches a flow path from the upstream side duct between the branch duct and the downstream side duct, wherein the valve mechanism comprises: a selector valve which is capable of shifting to a first position where the selector valve opens the upstream side duct to the downstream side duct and shuts the upstream side duct relative to the branch duct and a second position where the selector valve opens the upstream side duct to the branch duct and shuts the upstream side duct relative to the downstream side duct; an operating member which operates the selector valve from the outside; and a valve housing which communicates with the upstream side duct, the downstream side duct and the branch duct, wherein the selector valve comprises a cylindrical valve which is disposed slidably in an interior of the valve housing, and wherein the operating member comprises a valve stem which is fitted slidably in an interior of the selector valve, in which an operating portion at one end thereof penetrates the valve housing to project to the outside, which selectively opens a space formed on one end side of the selector valve to the upstream side duct or the atmosphere, and which causes the selector valve to shift to the first position or the second position.
