PROBLEM TO BE SOLVED: To provide a gear having a structure that can be made lightweight and can obtain wear resistance of a gear wheel part and a sufficient inertial force.SOLUTION: A gear 100 comprises a metallic rotating shaft part (such as a shaft 10), a metallic gear wheel part 20, and a resin connecting body 30 bonded to the rotating shaft part and the gear wheel part 20 respectively to connect the rotating shaft part and the gear wheel part 20 to each other. For example, the connecting body 30 covers both sides of a gear wheel body part 21 in the axial direction of the gear wheel body part 21 and is bonded to both sides respectively. |
