DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/056253
Kind Code:
A1
Abstract:
The drive device according to an embodiment is provided with gear sets (40, 50, 60, 70), a shaft (20), a first elastic body (23) and a second elastic body (72). The gear sets (40, 50, 60, 70) rotate due to the output of a driving source. The shaft (20) rotates by torque transmitted via the gear sets (40, 50, 60, 70). The first elastic body (23) biases the shaft (20) in the rotation direction. The second elastic body (72) assists the rotation of the shaft (20) in the rotation direction by biasing a gear, of the gears included in the gear sets (40, 50, 60, 70), that rotates on a different rotation axis from the shaft (20).
