PROBLEM TO BE SOLVED: To provide a gear member which does not produce variation of inside diameter and has high torque intensity even if two members are interconnected by press fitting and to provide a gear mechanism with the gear member and a manufacturing method of the gear member. SOLUTION: The gear member 1 has a structure in which the connected part 11c of a small diameter gear 11 is inserted with force to the connected hole 12b of a large diameter gear 12. The inner peripheral surface of the connected hole 12b is flat and a groove portion 11b is formed in the outer peripheral face of the connected part 11c and when the connected part 11c of the small diameter gear 11 is press-fitted to the connected hole 12b of the large diameter gear 12, the inner peripheral face of the connected hole 12b is plastically deformed so as to disposed between the grooves 11b, the small diameter gear 11 and the large diameter gear 12 can be connected with high intensity. Further, when the connected part 11c is press-fitted into the connected hole 12b, a large load is not applied to the connected part 11c side and the inner diameter dimension of the connected part 11c never shrinks.
