  • Patent number: 11097899
    Abstract: An objective is to develop a conveyor device capable of conveying a conveyance object in a plurality of directions. The conveyor device includes a roller portion (rotating body) 30 and a driving body 50. The rotating body 30 is rotatable around at least a first rotation axis 60, and the rotating body is rotatable around a second rotation axis 61 in a direction intersecting with the first rotation axis 60, and changes an attitude by rotating to change a direction of the first rotation axis 60. The driving body 50 is rotated by power around a third rotation axis 62, and the third rotation axis 62 extends in a direction intersecting with the first rotation axis 60. The driving body 50 is in contact with the rotating body at a position eccentric to one end in the direction of the first rotation axis 60 relative to the second rotation axis 61 regardless of attitude-changing of the rotating body.
