<P>PROBLEM TO BE SOLVED: To cut off a fluid channel and a transmission path when a leading part is not attached, with a simple structure by a robot hand. <P>SOLUTION: The robot hand allows free attachment and detachment of a hand body part 3 and a hand end part 4 having a holding part. The hand body part 3 has a second hole part 352, a sliding part 38 and an urging part 39 set in the second hole part 352, a second fluid channel 342 wherein a driving fluid for the holding part flows, and a transmission path 37 transmitting a signal from the holding part. Some parts of these flow channels and paths are formed in the sliding part 38. When the hand end part 4 is not attached, the sliding part 38 is located on a cut-off position by being urged by the urging part 39 and these flow channels and paths are cut off. When the hand end part 4 is attached, the sliding part 38 is located on a connection position by being pushed by the hand end part 4, and these flow channels and paths are connected to each other via the sliding part 38. Thus, the second flow channel 342 and the transmission path 37 are cut off when the hand end part 4 is not attached with a simple structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
