Abstract
A motor-type damper unit includes a motor for driving in a single direction, an opened/closed member for reciprocating in an opening direction and a closing direction with a fulcrum shaft serving as a center by a drive force of said motor, an intermittent drive gear formed with a tooth part in a predetermined part in a circumferential direction and rotation blocking parts at both ends of the tooth part, said intermittent drive gear for rotating by the drive force of said motor, a first transmission gear placed on the fulcrum shaft for engaging the tooth part of said intermittent drive gear, thereby rotating said opened/closed member in a predetermined direction and a second transmission gear for engaging the tooth part of said intermittent drive gear at a different position from said first transmission gear, for transmitting a rotation force of said intermittent drive gear to said first transmission gear and for rotating said first transmission gear in an opposite direction to the predetermined direction.
