A damping structure is formed of a base including at least one projecting portion having a shaft or a hole, and a first engaging portion; a rotating member including a first wall portion having the other of the hole or the shaft engaging the shaft or hole, a second wall portion facing the first wall portion to receive the projection therebetween so that when the first wall portion is supported by the projecting portion, a space is formed between the projecting portion and the second wall portion, and a second engaging portion; and a damper disposed in the space. The damper includes an inner shaft having a third engaging portion engaging the first or second engaging portion, and an outer shaft rotatably situated around the inner shaft to generate a damping force against a rotation of the inner shaft. The outer shaft has a fourth engaging portion engaging the first or second engaging portion to thereby provide a damping force to the rotating member.
