PROBLEM TO BE SOLVED: To provide a gear structure in which a gear member and a support member are connected by a method in which there are few projection parts to be rotational resistance and increase in weight can be suppressed.SOLUTION: In a gear structure, a support member includes a cylindrical support side fitting surface, a gear member includes: a cylindrical gear side fitting surface; a contact part projecting to the support member side in a first direction side of a shaft; and a caulking part deformed so as to project to the support member side in a second direction side of the shaft, and the hardness of the caulking part is harder than that of the support member. |
