Claims

[Scope of utility model registration request]

This is an air tool in which a grinding tool or the like is activated by the driving force of air, and the driving part is installed inside a casing that also serves as a handle. It is formed into an integrally molded cylindrical body, and the hollow part of the cylindrical body is provided with an air introduction passage communicating with the air supply passage and an exhaust conduit passage communicating with the exhaust passage, and a valve for starting a grinding cutting tool, etc. The valve housing, which has a substantially circular cross section that allows the assembly to be retrofitted, is airtightly inserted, the valve housing is fixed to the casing with mounting screws, and the starting valve assembly is retrofitted and fixed to the valve housing. tool.
