PROBLEM TO BE SOLVED: To provide a bearing mechanism capable of suppressing rigidity degradation while reducing loss torque than conventional tapered roller bearings.SOLUTION: A representative configuration of the invention is a bearing mechanism to pivotally support a gear shaft having a gear at one end thereof. The bearing mechanism includes a first bearing 200 disposed in the vicinity of the gear, and a second bearing 300 disposed opposite the gear of the gear shaft. The first bearing 200 is a multirow angular ball bearing. One of the multirow is of multipoint contact. |
