The first bearing rotatably supports a shaft extending in the axial direction along the rotation axis. A housing of the drive device has a first bearing holder that holds the first bearing. The second bearing is arranged between the shaft and the housing and rotatably supports the shaft. The second bearing is arranged in a space isolated from the first bearing holder.
