Title:
ROBOT HAND AND ROBOT
Document Type and Number:
Japanese Patent JP2013255958
Kind Code:
A
Abstract:

To provide a robot hand transmitting driving force of a piezoelectric motor to a movable part by a transmitting shaft and operating, avoiding the generation of force inclining the transmitting shaft.

A robot hand is moved by transmitting the driving force of a piezoelectric motor to a movable part via a transmitting shaft. A supporting part pushing and pressing the transmitting shaft in a direction opposite to a direction in which the piezoelectric motor pushes the transmitting shaft is arranged in an opposite side of the piezoelectric motor to the transmitting shaft because the piezoelectric motor is used while being pushed to the transmitting shaft. Thus, force inclining the transmitting shaft is not generated because force by which the piezoelectric motor pushes and presses the transmitting shaft can be received by the supporting part. As a result, various kinds of problems are prevented from being generated by the transmitting shaft unevenly abutting on a member supporting the transmitting shaft.
