Abstract
A bearing device includes a gear portion and a gear housing that houses the gear portion and stores a lubricant therein. The gear housing includes a side plate extending in a direction intersecting the axial direction, a recess recessed from the side plate toward the other side in the axial direction, a saucer opened upward, and a groove including a shaft opening opposing the gear housing and a peripheral opening opened to the recess. The gear portion includes an output shaft rotatably supported by the gear housing via a bearing, and a first gear connected to the output shaft. The saucer includes an opposing surface opposing an outer peripheral surface of the first gear. The groove is inclined downward toward the peripheral opening and reaches the bearing, and the shaft opening of the groove reaches the saucer.
