Abstract

See full text

An angle wrench has a simple structure and is capable of accurately measuring rotation angle. The angle wrench is used for tightening an object to be tightened by means of the rotation angle method, and includes a handle having a grip; a head section having a tightening head for tightening the object to be tightened, and a tail section that extends from the tightening head pivotally supported with respect to the handle via a head pin; torque-detecting mechanisms for detecting when the torque for tightening the object being tightened reaches the specified torque; and a rotation angle-measuring section for measuring the rotation angle of the angle wrench in a tightening action, on the basis of the angular velocity of the angle wrench around the axis of the object being tightened, after the torque-detecting mechanism has detected that the specified torque has been reached.
