PROBLEM TO BE SOLVED: To easily cope with cylindrical parts having various sizes by a method wherein when the circular parts different in an outside diameter are grasped, the central position of the circular part is always substantially grasped in the same position without varying and regulating the part of an automatic assembling device. SOLUTION: This assembling device is formed such that a pair of grasping arms 9 and 10 are rotatably fitted in support shafts 16 and 18 disposed separately from each other. The shapes of V-shaped grasping parts 9d and 10d are formed such that the opening angleαof the tip sides of the V-shaped grasping parts 9d and 10d with a perpendicular V from the bottom parts 9e and 10e of a line segment L to intercouple support shafts 16 and 18 and the bottoms 9e and 10e of the V-shaped grasping parts 9d and 10d is decreased to a value lower than the opening angleβof the support shafts 16 and 18 sides of the V-shaped grasping parts 9d and 10d therewith. Even when the outside diameter of the circular part 6 is varied when the circular part 6 is grasped by the V-shaped grasping parts 9d and 10d through rotation of a pair of the grasping arms 9 and 10, the central position of the circular part 6 is grasped in a specified position.
