Traditionally, when assembling parts, bolts and nuts are
It is very common to join products together, but usually bolts and
When tightening with a nut, torque was applied to the bolt to tighten it. However, in this case,
Since the torque of the bolt is transmitted to the nut, a reaction force against the torque is required to hold the nut. Conventional robot hands that hold and transport nuts have held nuts with a force that exceeds this reaction force, but this requires a drive unit with a large force, which has the disadvantage of making the robot hand complex and heavy. .

The present invention has been made to eliminate the drawbacks of the conventional method, and includes a retainer 114 formed with a U groove in a rigid plate of the nut retaining pawl to match the width across flats of the nut. By a robot hand having a leaf spring for guiding the width of the nut at the tip 4 of the nut holding claw,
The nut is held by allowing the bolt's torque to be received by a rigid plate. There is no need for a drive unit to hold the nut, and because the leaf spring guides the two widths of the nut, there is no need to align the two sides of the nut one distance apart on the nut supply side. This allows the nut to be set in the

As described above, according to the present invention, when tightening bolts and nuts, by using a holding pawl made of a rigid plate in the nut holding part that receives the reaction force of the torque of the bolt, the nut holding part can be tightened. There is no need for a drive unit to set the nut on the rigid plate, and the guide leaf spring for setting the nut on the rigid plate eliminates the need to position the width across flats of the nut on the nut supply side, making the robot hand and the nut supply side very easy to use. It has immediate effects such as a simple structure.
