<P>PROBLEM TO BE SOLVED: To reduce the thickness and size of each arm of a horizontal articulated robot while enhancing the positioning accuracy by improving the operability of each arm. <P>SOLUTION: A first arm 3 includes, on an upper surface of the front end portion of the first arm 3, a first arm protruding portion 43 having a surface positioned higher than an upper surface on the base end side of the first arm 3. A second arm 27 includes, on a lower surface of the front end portion of the second arm 27, a second arm protruding portion 44 having a surface positioned lower than a lower surface on the base end side of the second arm 27. The first arm protruding portion 43 and the second arm protruding portion 44 are positioned so as to be overlapped with each other at least partially in a vertical positioning height range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
