<P>PROBLEM TO BE SOLVED: To shorten axial dimensions, and to restrain reduction in lubricity of a crankshaft bearing, in an eccentric reduction gear in which a crank transmission gear is fixed to a crankshaft. Ž<P>SOLUTION: The crank transmission gear 49 meshing with an input gear 15 is fixed to the other end side of the crankshaft 23. The crank transmission gear 49 is provided with a gear through-hole 56 penetratingly formed so as to be opposed to a second crankshaft bearing 35 for rotatably holding the other end side of the crankshaft 23 to an end part carrier 26.
