Document Type and Number:

WIPO Patent Application WO/2007/077698

Kind Code:

A1

Abstract:

A sealed worm gear type finger joint unit (1) for a robot hand has a circular opening (82) in a gear box case (4) of the unit, and the opening is closed by a rubber bush (13). When the rubber bush (13) is removed, a shaft end face (11a) of a worm shaft section (11A) is exposed from the circular opening (82), and this makes a tool engagement section (11b) formed on the shaft end face is accessible from the outside. A tool for turning the worm shaft section (11A) is fitted in the tool engagement section (11b), and the worm shaft section (11A) can be easily turned by the tool. Turning the worm shaft section (11A) turns a worm (2), turning a worm wheel (3) meshing with the worm (2), and this turns the joint shaft (12). As a result, a swing arm connected to shaft end sections (12a, 12b) of the joint shaft (12) can be moved to a predetermined position. In the finger joint unit, the joint shaft can be easily manually turned.
