IMPACT FASTENING TOOL AND TORQUE TESTER

摘要

Provided are: an impact fastening tool (1) which prevents a torque detecting means (3) from missing a signal and extends service life by adopting a fixed connector (5) that prevents the trouble of being instantaneously separated (bounced) from a rotating electrode (4) by intermittent impacts and has a shape allowing the progression of friction to be delayed structurally; and a torque tester (6). Both end portions (50, 51) of the fixed connector (5) are fixed, and at least two protrusion portions (52, 53) are formed between the both end portions (50, 51). The rotating electrode (4) is disposed between one protrusion portion (52) and the other protrusion portion (53) such that the rotating electrode contacts the fixed connector (5) at two or more points or in a line form. A signal required for the torque detecting means (3) is transmitted through the contact between the rotating electrode (4) and the fixed connector (5).
