Abstract:
1. A robot hand having an attachment portion that is held when incorporated into a robot, the robot hand comprising: first and second carbon-fiber-reinforced plastic layers laminated to each other; and a vibration-damping elastic layer disposed between the first carbon-fiber-reinforced plastic layer and the second carbon-fiber-reinforced plastic layer, wherein the first and second carbon-fiber-reinforced plastic layers are plate-like and integrally formed with each other, the vibration-damping elastic layer includes a viscoelastic resin region including a viscoelastic resin and a high-rigidity resin region including a high-rigidity resin that has higher rigidity than that of the viscoelastic resin, and the viscoelastic resin region and the high-rigidity resin region are alternately arranged in the attachment portion, a number of viscoelastic resin regions is two or more in the attachment portion, and a number of high-rigidity resin regions is one more than the number of the viscoelastic resin regions in the attachment portion.
