  • Patent number: 11156275
    Abstract: The drive device drives a drive member and is provided with a power-side gear and a drive-side gear. The power-side gear is driven by a force output from a power source so as to drive the drive member in a range between a first stop position and a second stop position. In addition, the drive-side gear meshes with the power-side gear and transmits the force obtained from the power-side gear to the drive member. Also, the drive-side gear and the power-side gear are configured so as to disengage from each other when the drive member has reached the first stop position and/or the second stop position.
