Abstract
A multi-joint finger unit () has first and second joint sections () constructed by using bevel gears. In each joint section (), the section where a driving bevel gear () and a driven bevel gear () mesh with each other and also a bearing section of a joint shaft () are assembled in a tubular housing () whose forward end is closed. Rear end openings (A,) of the tubular housings () are closed by a tubular housing () at a finger root and a tubular housing () at a finger body section. The section where the gears of the joint sections () mesh and the bearing section are substantially sealed, so that a foreign matter is prevented from entering from the outside to these sections and lubricant does not leaks from these sections. The multi-joint finger unit is suitable for use in place where thick powder dust is present and in a clean room.
