<P>PROBLEM TO BE SOLVED: To provide a friction mechanism, a geared motor having this friction mechanism and a manufacturing method of the friction mechanism, capable of coping with high friction, and capable of forming a fitting hole having high circularity. Ž<P>SOLUTION: This friction mechanism 9 push-expands an elastic deformation part 915 of a first rotary member 91 to the outside by an inside ring-shaped energizing member 93, to be allowed to abut on an inner peripheral side surface 921a of the fitting hole 921 of a second rotary member 92. The first rotary member 91 is made of resin, and the second rotary member 92 is a metallic sintered body. Thus, there is an advantage capable of forming the fitting hole 921 having high circularity. The second rotary member 92 is superior in slidability since a resin coating layer 927 is formed on a surface of the sintered body. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
