摘要： A gear transmission device includes a frame, a sun gear, a driven gear, a planetary gear, a contact member, and a guide. The guide guides the contact member as described below. When the planetary gear is at a meshing position, a first tooth portion and a first contact portion of the contact member are away from the planetary gear. When the planetary gear is at a farthest position, the first contact portion is in contact with the planetary gear and the first tooth portion is away from the planetary gear. When the planetary gear is between the meshing position and the farthest position, the first tooth portion moves in mesh with the planetary gear in a direction opposite to a moving direction of the planetary gear around the sun gear, and the first contact portion is switched between a state in contact with the planetary gear and a state away from the planetary gear.
