PROBLEM TO BE SOLVED: To create a both ends-support arm member by die-cast casting.SOLUTION: There is provided an articulated robot (1) which includes: a first arm member (A1) having a U-shaped part (10) composed of two protrusions (11, 12) parallel to each other; and a second arm member (A2) rotatably connected to two protrusions of the U-shaped part in a double support manner, wherein the first arm member is formed of two half-mold parts (31, 32) which are divided between two protrusions of the U-shaped part and in a plane vertical to a rotational axis line of the second arm member. Further, the first arm member includes: connection parts (45a and 45b) for connecting two half-mold parts to each other. |
