ABSTRACT:
A multi-joint finger unit (1) has first and second joint sections (3, 5) constructed by using bevel gears. In each joint section (3, 5), the section where a driving bevel gear (10, 44) and a driven bevel gear (14, 56) mesh with each other and also a bearing section of a joint shaft (15, 57) are assembled in a tubular housing (13, 51) whose forward end is closed. Rear end openings (13A,52) of the tubular housings (13, 51) are closed by a tubular housing (7) at a finger root and a tubular housing (41) at a finger body section. The section where the gears of the joint sections (3, 5) 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.
