PROBLEM TO BE SOLVED: To provide an epicyclic gear set capable of preventing excessive wear by ensuring sufficient lubrication without using any additional constituent element. SOLUTION: A laminated frame includes a first end plate, a second end plate and a connecting means joins the two end plates so that a window to locate the position of an epicyclic gearing device is formed between them. At least one of the first and second end plates is made of a material consisting of a number of layers joined so that a non-uniform internal structure is generated.
