摘要： A bolt-tightening tool for tightening two bolts at the same time. The bolt-tightening tool includes a first rotating shaft coupled with a motor shaft and a second rotating shaft coupled with a motor case. A first bolt is tightened with the first rotating shaft, while a second bolt is tightened with the second rotating shaft, whereby the first and the second bolts are tightened with a same amount of torque.

摘要： A tappet clearance automatic adjusting device comprising an adjusting unit for advancing/retracting an adjust screw from the forward end of a rocker arm and adjusting the projection amount, a torque detecting section for detecting the torque by rotating the adjust screw, and a control mechanism section for controlling the adjusting unit based on a torque value measured at the torque detecting section. The control mechanism section starts retracting the adjust screw when a valve is opened and continuously measures the torque value obtained when the valve is closed. A position, corresponding to time when variation in the filtering value obtained by smoothing the torque value through moving average is a threshold value or smaller, is detected as a reference point and the adjust screw is retracted from the reference point by a set amount.

The control mechanism section measures the torque value continuously when a valve is closed by retracting the adjust screw from the open state of the valve. A rotation reference position corresponding to the intersection of a first approximation line and a second approximation line approximating the sections immediately before and after the inflection point of differential value of the torque value is detected as a reference point, and the adjust screw is retracted by a set amount from the reference point.
