載のエア工具におけるトルク制御機構。[Scope of Claim for Utility Model Registration] (1) In an air tool that opens and closes the air circuit of an air motor using a main valve, a flow rate regulating valve that communicates with the air cylinder is connected to the static pressure section on the inlet side of the main valve of the air circuit. In an air tool, the shaft of the main valve is connected and interlocked with the piston of the air cylinder, and has an automatic adjustment function so that the set torque is automatically achieved in response to pressure fluctuations in the air source. Torque control mechanism. (2) A torque control mechanism for an air tool according to claim 1 of the utility model registration claim, in which an air tank is interposed between a flow rate regulating valve and an air cylinder.
