SCREW TIGHTENING DEVICE AND TORQUE SENSOR
Document Type and Number:
WIPO Patent Application WO/2010/016185
Kind Code:
A1
Abstract:
A screw tightening device having a small-sized clutch, reduced in size and weight, and easily operable.
A clutch (5) is directly connected to the output side of a DC motor (3), and as result, the output of the DC motor (3) is less than the output of conventionally used motors. This reduces the size of the DC motor (3) and the clutch (5). Accordingly, the size and weight of a device body (1) are less than those of conventional products.
